  *) New 'passwd' tool for crypt(3) and apr1 password hashes.
B
Bodo Möller 已提交
8 9
     [Bodo Moeller]

10 11 12
  *) Add command line password options to the remaining applications.
     [Steve Henson]

13 14 15 16 17 18 19
  *) Bug fix for BN_div_recp() for numerators with an even number of
     bits.
     [Ulf Möller]

  *) More tests in bntest.c, and changed test_bn output.
     [Ulf Möller]

20 21 22
  *) ./config recognizes MacOS X now.
     [Andy Polyakov]

23 24 25 26
  *) Bug fix for BN_div() when the first words of num and divsor are
     equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
     [Ulf Möller]

27 28 29 30
  *) Add support for various broken PKCS#8 formats, and command line
     options to produce them.
     [Steve Henson]

31 32 33 34 35 36 37 38
  *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
     get temporary BIGNUMs from a BN_CTX.
     [Ulf Möller]

  *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
     for p == 0.
     [Ulf Möller]

39 40 41 42 43 44 45 46 47
  *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
     include a #define from the old name to the new. The original intent
     was that statically linked binaries could for example just call
     SSLeay_add_all_ciphers() to just add ciphers to the table and not
     link with digests. This never worked becayse SSLeay_add_all_digests()
     and SSLeay_add_all_ciphers() were in the same source file so calling
     one would link with the other. They are now in separate source files.

48 49 50
  *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
     [Steve Henson]

51 52 53 54 55
  *) Use a less unusual form of the Miller-Rabin primality test (it used
     a binary algorithm for exponentiation integrated into the Miller-Rabin
     loop, our standard modexp algorithms are faster).
     [Bodo Moeller]

59 60 61 62
  *) Source code cleanups: use const where appropriate, eliminate casts,
     use void * instead of char * in lhash.
     [Ulf Möller] 

63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78
  *) Bugfix: ssl3_send_server_key_exchange was not restartable
     (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
     this the server could overwrite ephemeral keys that the client
     has already seen).
     [Bodo Moeller]

  *) Turn DSA_is_prime into a macro that calls BN_is_prime,
     using 50 iterations of the Rabin-Miller test.

     DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
     iterations of the Rabin-Miller test as required by the appendix
     to FIPS PUB 186[-1]) instead of DSA_is_prime.
     As BN_is_prime_fasttest includes trial division, DSA parameter
     generation becomes much faster.

     This implies a change for the callback functions in DSA_is_prime
79 80 81 82 83 84 85 86 87
     and DSA_generate_parameters: The callback function is called once
     for each positive witness in the Rabin-Miller test, not just
     occasionally in the inner loop; and the parameters to the
     callback function now provide an iteration count for the outer
     loop rather than for the current invocation of the inner loop.
     DSA_generate_parameters additionally can call the callback
     function with an 'iteration count' of -1, meaning that a
     candidate has passed the trial division test (when q is generated 
     from an application-provided seed, trial division is skipped).
88 89
     [Bodo Moeller]

90
  *) New function BN_is_prime_fasttest that optionally does trial
91 92 93
     division before starting the Rabin-Miller test and has
     an additional BN_CTX * argument (whereas BN_is_prime always
     has to allocate at least one BN_CTX).
94 95 96
     'callback(1, -1, cb_arg)' is called when a number has passed the
     trial division stage.
     [Bodo Moeller]

     as ASN1_TIME.

Ulf Möller 已提交
108 109 110 111 112 113
  *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
     bignum version of BN_from_montgomery() with the working code from
     SSLeay 0.9.0 (the word based version is faster anyway), and clean up
     the comments.
     [Ulf Möller]

B
Bodo Möller 已提交
114 115 116 117 118
  *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
     made it impossible to use the same SSL_SESSION data structure in
     SSL2 clients in multiple threads.
     [Bodo Moeller]

Bodo Möller 已提交
119 120 121 122
  *) The return value of RAND_load_file() no longer counts bytes obtained
     by stat().  RAND_load_file(..., -1) is new and uses the complete file
     to seed the PRNG (previously an explicit byte count was required).

Dr. Stephen Henson 已提交
124 125 126 127
  *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
     used (char *) instead of (void *) and had casts all over the place.
     [Steve Henson]

128 129 130
  *) Make BN_generate_prime() return NULL on error if ret!=NULL.
     [Ulf Möller]

131 132 133 134
  *) Retain source code compatibility for BN_prime_checks macro:
     BN_is_prime(..., BN_prime_checks, ...) now uses
     BN_prime_checks_for_size to determine the appropriate number of
     Rabin-Miller iterations.
135 136 137 138 139 140 141
     [Ulf Möller]

  *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
     DH_CHECK_P_NOT_SAFE_PRIME.
     (Check if this is true? OpenPGP calls them "strong".)
     [Ulf Möller]

Dr. Stephen Henson 已提交
142 143 144 145 146
  *) Merge the functionality of "dh" and "gendh" programs into a new program
     "dhparam". The old programs are retained for now but will handle DH keys
     (instead of parameters) in future.
     [Steve Henson]

147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167
  *) Make the ciphers, s_server and s_client programs check the return values
     when a new cipher list is set.
     [Steve Henson]

  *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
     ciphers. Before when the 56bit ciphers were enabled the sorting was
     wrong.

     The syntax for the cipher sorting has been extended to support sorting by
     cipher-strength (using the strength_bits hard coded in the tables).
     The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).

     Fix a bug in the cipher-command parser: when supplying a cipher command
     string with an "undefined" symbol (neither command nor alphanumeric
     [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
     an error is flagged.

     Due to the strength-sorting extension, the code of the
     ssl_create_cipher_list() function was completely rearranged. I hope that
     the readability was also increased :-)

169 170 171 172 173 174 175
  *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
     for the first serial number and places 2 in the serial number file. This
     avoids problems when the root CA is created with serial number zero and
     the first user certificate has the same issuer name and serial number
     as the root CA.
     [Steve Henson]

176 177 178 179
  *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
     the new code. Add documentation for this stuff.
     [Steve Henson]

180 181 182 183 184 185 186 187 188 189
  *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
     X509_*() to X509at_*() on the grounds that they don't handle X509
     structures and behave in an analagous way to the X509v3 functions:
     they shouldn't be called directly but wrapper functions should be used
     instead.

     So we also now have some wrapper functions that call the X509at functions
     when passed certificate requests. (TO DO: similar things can be done with
     PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
     things. Some of these need some d2i or i2d and print functionality
190
     because they handle more complex structures.)
191 192
     [Steve Henson]

193 194 195 196 197
  *) Add missing #ifndefs that caused missing symbols when building libssl
     as a shared library without RSA.  Use #ifndef NO_SSL2 instead of
     NO_RSA in ssl/s2*.c. 
     [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]

198
  *) Precautions against using the PRNG uninitialized: RAND_bytes() now
199 200
     has a return value which indicates the quality of the random data
     (1 = ok, 0 = not seeded).  Also an error is recorded on the thread's
201 202
     error queue. New function RAND_pseudo_bytes() generates output that is
     guaranteed to be unique but not unpredictable.
203 204
     [Ulf Möller]

205 206
  *) Do more iterations of Rabin-Miller probable prime test (specifically,
     3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
207
     instead of only 2 for all lengths; see BN_prime_checks_for_size definition
208
     in crypto/bn/bn_prime.c for the complete table).  This guarantees a
209
     false-positive rate of at most 2^-80 for random input.
210 211
     [Bodo Moeller]

212
  *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
213 214
     [Bodo Moeller]

215 216 217 218 219 220 221 222 223 224
  *) New function X509_CTX_rget_chain(), this returns the chain
     from an X509_CTX structure with a dup of the stack and all
     the X509 reference counts upped: so the stack will exist
     after X509_CTX_cleanup() has been called. Modify pkcs12.c
     to use this.

     Also make SSL_SESSION_print() print out the verify return
     code.
     [Steve Henson]

225 226 227 228 229 230
  *) Add manpage for the pkcs12 command. Also change the default
     behaviour so MAC iteration counts are used unless the new
     -nomaciter option is used. This improves file security and
     only older versions of MSIE (4.0 for example) need it.
     [Steve Henson]

231 232 233
  *) Honor the no-xxx Configure options when creating .DEF files.
     [Ulf Möller]

234 235 236 237 238 239 240 241 242 243 244
  *) Add PKCS#10 attributes to field table: challengePassword, 
     unstructuredName and unstructuredAddress. These are taken from
     draft PKCS#9 v2.0 but are compatible with v1.2 provided no 
     international characters are used.

     More changes to X509_ATTRIBUTE code: allow the setting of types
     based on strings. Remove the 'loc' parameter when adding
     attributes because these will be a SET OF encoding which is sorted
     in ASN1 order.
     [Steve Henson]

245 246 247 248 249 250 251 252 253
  *) Initial changes to the 'req' utility to allow request generation
     automation. This will allow an application to just generate a template
     file containing all the field values and have req construct the
     request.

     Initial support for X509_ATTRIBUTE handling. Stacks of these are
     used all over the place including certificate requests and PKCS#7
     structures. They are currently handled manually where necessary with
     some primitive wrappers for PKCS#7. The new functions behave in a
254
     manner analogous to the X509 extension functions: they allow
255 256 257 258 259
     attributes to be looked up by NID and added.

     Later something similar to the X509V3 code would be desirable to
     automatically handle the encoding, decoding and printing of the
     more complex types. The string types like challengePassword can
260
     be handled by the string table functions.
261 262 263 264 265 266 267 268 269

     Also modified the multi byte string table handling. Now there is
     a 'global mask' which masks out certain types. The table itself
     can use the flag STABLE_NO_MASK to ignore the mask setting: this
     is useful when for example there is only one permissible type
     (as in countryName) and using the mask might result in no valid
     types at all.
     [Steve Henson]

270 271 272 273 274 275 276 277 278 279
  *) Clean up 'Finished' handling, and add functions SSL_get_finished and
     SSL_get_peer_finished to allow applications to obtain the latest
     Finished messages sent to the peer or expected from the peer,
     respectively.  (SSL_get_peer_finished is usually the Finished message
     actually received from the peer, otherwise the protocol will be aborted.)

     As the Finished message are message digests of the complete handshake
     (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
     be used for external authentication procedures when the authentication
     provided by SSL/TLS is not desired or is not enough.
280 281
     [Bodo Moeller]

282 283
  *) Enhanced support for Alpha Linux is added. Now ./config checks if
     the host supports BWX extension and if Compaq C is present on the
284
     $PATH. Just exploiting of the BWX extension results in 20-30%
285 286 287 288 289
     performance kick for some algorithms, e.g. DES and RC4 to mention
     a couple. Compaq C in turn generates ~20% faster code for MD5 and
     SHA1.
     [Andy Polyakov]

290 291 292 293 294 295 296 297 298 299 300 301 302 303 304
  *) Add support for MS "fast SGC". This is arguably a violation of the
     SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
     weak crypto and after checking the certificate is SGC a second one
     with strong crypto. MS SGC stops the first handshake after receiving
     the server certificate message and sends a second client hello. Since
     a server will typically do all the time consuming operations before
     expecting any further messages from the client (server key exchange
     is the most expensive) there is little difference between the two.

     To get OpenSSL to support MS SGC we have to permit a second client
     hello message after we have sent server done. In addition we have to
     reset the MAC if we do get this second client hello and include the
     data just received.
     [Steve Henson]

305 306 307 308 309 310 311 312
  *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
     if a DER encoded private key is RSA or DSA traditional format. Changed
     d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
     format DER encoded private key. Newer code should use PKCS#8 format which
     has the key type encoded in the ASN1 structure. Added DER private key
     support to pkcs8 application.
     [Steve Henson]

313 314 315 316 317 318 319 320
  *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
     ciphersuites has been selected (as required by the SSL 3/TLS 1
     specifications).  Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
     is set, we interpret this as a request to violate the specification
     (the worst that can happen is a handshake failure, and 'correct'
     behaviour would result in a handshake failure anyway).
     [Bodo Moeller]

321 322 323 324 325 326 327 328
  *) In SSL_CTX_add_session, take into account that there might be multiple
     SSL_SESSION structures with the same session ID (e.g. when two threads
     concurrently obtain them from an external cache).
     The internal cache can handle only one SSL_SESSION with a given ID,
     so if there's a conflict, we now throw out the old one to achieve
     consistency.
     [Bodo Moeller]

329 330 331 332 333 334 335
  *) Add OIDs for idea and blowfish in CBC mode. This will allow both
     to be used in PKCS#5 v2.0 and S/MIME.  Also add checking to
     some routines that use cipher OIDs: some ciphers do not have OIDs
     defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
     example.
     [Steve Henson]

336 337 338 339 340 341 342 343 344
  *) Simplify the trust setting structure and code. Now we just have
     two sequences of OIDs for trusted and rejected settings. These will
     typically have values the same as the extended key usage extension
     and any application specific purposes.

     The trust checking code now has a default behaviour: it will just
     check for an object with the same NID as the passed id. Functions can
     be provided to override either the default behaviour or the behaviour
     for a given id. SSL client, server and email already have functions
345
     in place for compatibility: they check the NID and also return "trusted"
346 347 348
     if the certificate is self signed.
     [Steve Henson]

349 350 351 352
  *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
     traditional format into an EVP_PKEY structure.
     [Steve Henson]

353 354
  *) Add a password callback function PEM_cb() which either prompts for
     a password if usr_data is NULL or otherwise assumes it is a null
355
     terminated password. Allow passwords to be passed on command line
356 357 358
     environment or config files in a few more utilities.
     [Steve Henson]

359 360 361 362 363 364
  *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
     keys. Add some short names for PKCS#8 PBE algorithms and allow them
     to be specified on the command line for the pkcs8 and pkcs12 utilities.
     Update documentation.
     [Steve Henson]

Dr. Stephen Henson 已提交
365 366
  *) Support for ASN1 "NULL" type. This could be handled before by using
     ASN1_TYPE but there wasn't any function that would try to read a NULL
367
     and produce an error if it couldn't. For compatibility we also have
D
Dr. Stephen Henson 已提交
368 369 370 371
     ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
     don't allocate anything because they don't need to.
     [Steve Henson]

372 373 374 375
  *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
     for details.
     [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]

376 377 378
  *) Rebuild of the memory allocation routines used by OpenSSL code and
     possibly others as well.  The purpose is to make an interface that
     provide hooks so anyone can build a separate set of allocation and
379 380 381
     deallocation routines to be used by OpenSSL, for example memory
     pool implementations, or something else, which was previously hard
     since Malloc(), Realloc() and Free() were defined as macros having
R
Richard Levitte 已提交
382 383 384 385
     the values malloc, realloc and free, respectively (except for Win32
     compilations).  The same is provided for memory debugging code.
     OpenSSL already comes with functionality to find memory leaks, but
     this gives people a chance to debug other memory problems.
386

387 388 389 390 391 392
     With these changes, a new set of functions and macros have appeared:

       CRYPTO_set_mem_debug_functions()		[F]
       CRYPTO_get_mem_debug_functions()		[F]
       CRYPTO_dbg_set_options()			[F]
       CRYPTO_dbg_get_options()			[F]
393
       CRYPTO_malloc_debug_init()		[M]
394 395 396

     The memory debug functions are NULL by default, unless the library
     is compiled with CRYPTO_MDEBUG or friends is defined.  If someone
397 398 399 400 401 402 403 404
     wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
     gives the standard debugging functions that come with OpenSSL) or
     CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
     provided by the library user) must be used.  When the standard
     debugging functions are used, CRYPTO_dbg_set_options can be used to
     request additional information:
     CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
     the CRYPTO_MDEBUG_xxx macro when compiling the library.   
405 406 407 408 409 410 411 412 413 414 415 416 417 418

     Also, things like CRYPTO_set_mem_functions will always give the
     expected result (the new set of functions is used for allocation
     and deallocation) at all times, regardless of platform and compiler
     options.

     To finish it up, some functions that were never use in any other
     way than through macros have a new API and new semantic:

       CRYPTO_dbg_malloc()
       CRYPTO_dbg_realloc()
       CRYPTO_dbg_free()

     All macros of value have retained their old syntax.

  *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
     ordering of SMIMECapabilities wasn't in "strength order" and there
     was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
     algorithm.

  *) Some ASN1 types with illegal zero length encoding (INTEGER,
     ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.

431 432 433 434 435 436 437 438
  *) Merge in my S/MIME library for OpenSSL. This provides a simple
     S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
     functionality to handle multipart/signed properly) and a utility
     called 'smime' to call all this stuff. This is based on code I
     originally wrote for Celo who have kindly allowed it to be
     included in OpenSSL.

  *) Add variants des_set_key_checked and des_set_key_unchecked of
     des_set_key (aka des_key_sched).  Global variable des_check_key
     decides which of these is called by des_set_key; this way
     des_check_key behaves as it always did, but applications and
     the library itself, which was buggy for des_check_key == 1,
     have a cleaner way to pick the version they need.

  *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
     dynamic mix. In both cases the ids can be used as an index into the
     table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
     functions so they accept a list of the field values and the
     application doesn't need to directly manipulate the X509_TRUST
     structure.
     [Steve Henson]

  *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
     need initialising.

  *) Modify the way the V3 extension code looks up extensions. This now
     works in a similar way to the object code: we have some "standard"
     extensions in a static table which is searched with OBJ_bsearch()
     and the application can add dynamic ones if needed. The file
     crypto/x509v3/ext_dat.h now has the info: this file needs to be
     updated whenever a new extension is added to the core code and kept
     in ext_nid order. There is a simple program 'tabtest.c' which checks
     this. New extensions are not added too often so this file can readily
     be maintained manually.

     There are two big advantages in doing things this way. The extensions
     can be looked up immediately and no longer need to be "added" using
     X509V3_add_standard_extensions(): this function now does nothing.
     [Side note: I get *lots* of email saying the extension code doesn't
      work because people forget to call this function]
     Also no dynamic allocation is done unless new extensions are added:
     so if we don't add custom extensions there is no need to call
     X509V3_EXT_cleanup().
     [Steve Henson]

483 484 485 486 487 488
  *) Modify enc utility's salting as follows: make salting the default. Add a
     magic header, so unsalted files fail gracefully instead of just decrypting
     to garbage. This is because not salting is a big security hole, so people
     should be discouraged from doing it.
     [Ben Laurie]

489 490 491 492 493 494 495 496
  *) Fixes and enhancements to the 'x509' utility. It allowed a message
     digest to be passed on the command line but it only used this
     parameter when signing a certificate. Modified so all relevant
     operations are affected by the digest parameter including the
     -fingerprint and -x509toreq options. Also -x509toreq choked if a
     DSA key was used because it didn't fix the digest.
     [Steve Henson]

497 498 499 500 501
  *) Initial certificate chain verify code. Currently tests the untrusted
     certificates for consistency with the verify purpose (which is set
     when the X509_STORE_CTX structure is set up) and checks the pathlength.

     There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
502 503
     this is because it will reject chains with invalid extensions whereas
     every previous version of OpenSSL and SSLeay made no checks at all.
504 505 506 507 508 509 510

     Trust code: checks the root CA for the relevant trust settings. Trust
     settings have an initial value consistent with the verify purpose: e.g.
     if the verify purpose is for SSL client use it expects the CA to be
     trusted for SSL client use. However the default value can be changed to
     permit custom trust settings: one example of this would be to only trust
     certificates from a specific "secure" set of CAs.
511 512 513 514

     Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
     which should be used for version portability: especially since the
     verify structure is likely to change more often now.
515

516 517 518 519
     SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
     to set them. If not set then assume SSL clients will verify SSL servers
     and vice versa.

520 521 522 523
     Two new options to the verify program: -untrusted allows a set of
     untrusted certificates to be passed in and -purpose which sets the
     intended purpose of the certificate. If a purpose is set then the
     new chain verify code is used to check extension consistency.

  *) Support for the authority information access extension.

     [Steve Henson]

529 530 531 532 533
  *) Modify RSA and DSA PEM read routines to transparently handle
     PKCS#8 format private keys. New *_PUBKEY_* functions that handle
     public keys in a format compatible with certificate
     SubjectPublicKeyInfo structures. Unfortunately there were already
     functions called *_PublicKey_* which used various odd formats so
534
     these are retained for compatibility: however the DSA variants were
535 536 537 538 539 540 541 542 543 544
     never in a public release so they have been deleted. Changed dsa/rsa
     utilities to handle the new format: note no releases ever handled public
     keys so we should be OK.

     The primary motivation for this change is to avoid the same fiasco
     that dogs private keys: there are several incompatible private key
     formats some of which are standard and some OpenSSL specific and
     require various evil hacks to allow partial transparent handling and
     even then it doesn't work with DER formats. Given the option anything
     other than PKCS#8 should be dumped: but the other formats have to
545
     stay in the name of compatibility.
546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572

     With public keys and the benefit of hindsight one standard format 
     is used which works with EVP_PKEY, RSA or DSA structures: though
     it clearly returns an error if you try to read the wrong kind of key.

     Added a -pubkey option to the 'x509' utility to output the public key.
     Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() and add
     EVP_PKEY_rset_*() functions that do the same as the EVP_PKEY_assign_*()
     except they up the reference count of the added key (they don't "swallow"
     the supplied key).
     [Steve Henson]

  *) Fixes to crypto/x509/by_file.c the code to read in certificates and
     CRLs would fail if the file contained no certificates or no CRLs:
     added a new function to read in both types and return the number
     read: this means that if none are read it will be an error. The
     DER versions of the certificate and CRL reader would always fail
     because it isn't possible to mix certificates and CRLs in DER format
     without choking one or the other routine. Changed this to just read
     a certificate: this is the best we can do. Also modified the code
     in apps/verify.c to take notice of return codes: it was previously
     attempting to read in certificates from NULL pointers and ignoring
     any errors: this is one reason why the cert and CRL reader seemed
     to work. It doesn't check return codes from the default certificate
     routines: these may well fail if the certificates aren't installed.

576 577 578 579 580 581 582 583 584 585 586 587 588
  *) First update to verify code. Change the verify utility
     so it warns if it is passed a self signed certificate:
     for consistency with the normal behaviour. X509_verify
     has been modified to it will now verify a self signed
     certificate if *exactly* the same certificate appears
     in the store: it was previously impossible to trust a
     single self signed certificate. This means that:
     openssl verify ss.pem
     now gives a warning about a self signed certificate but
     openssl verify -CAfile ss.pem ss.pem
     is OK.
     [Steve Henson]

589 590 591 592 593 594 595 596 597 598 599
  *) For servers, store verify_result in SSL_SESSION data structure
     (and add it to external session representation).
     This is needed when client certificate verifications fails,
     but an application-provided verification callback (set by
     SSL_CTX_set_cert_verify_callback) allows accepting the session
     anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
     but returns 1): When the session is reused, we have to set
     ssl->verify_result to the appropriate error code to avoid
     security holes.

629 630
  *) Add the possibility to add extra information to the memory leak
     detecting output, to form tracebacks, showing from where each
631 632 633 634 635
     allocation was originated: CRYPTO_push_info("constant string") adds
     the string plus current file name and line number to a per-thread
     stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
     is like calling CYRPTO_pop_info() until the stack is empty.
     Also updated memory leak detection code to be multi-thread-safe.

     OSes like Unix) or read from the environment. Update the

651 652 653 654

     leaking and not finding already revoked certificates.
     [Steve Henson]

655 656 657 658 659
  *) Extensive changes to support certificate auxiliary information.
     This involves the use of X509_CERT_AUX structure and X509_AUX
     functions. An X509_AUX function such as PEM_read_X509_AUX()
     can still read in a certificate file in the usual way but it
     will also read in any additional "auxiliary information". By
660
     doing things this way a fair degree of compatibility can be
661 662 663 664 665 666 667 668 669 670
     retained: existing certificates can have this information added
     using the new 'x509' options. 

     Current auxiliary information includes an "alias" and some trust
     settings. The trust settings will ultimately be used in enhanced
     certificate chain verification routines: currently a certificate
     can only be trusted if it is self signed and then it is trusted
     for all purposes.
     [Steve Henson]

671 672 673 674 675
  *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
     The problem was that one of the replacement routines had not been working
     since SSLeay releases.  For now the offending routine has been replaced
     with non-optimised assembler.  Even so, this now gives around 95%
     performance improvement for 1024 bit RSA signs.
676 677
     [Mark Cox]

678 679 680 681 682
  *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 
     handling. Most clients have the effective key size in bits equal to
     the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
     A few however don't do this and instead use the size of the decrypted key
     to determine the RC2 key length and the AlgorithmIdentifier to determine
683
     the effective key length. In this case the effective key length can still
684 685 686 687 688 689
     be 40 bits but the key length can be 168 bits for example. This is fixed
     by manually forcing an RC2 key into the EVP_PKEY structure because the
     EVP code can't currently handle unusual RC2 key sizes: it always assumes
     the key length and effective key length are equal.

  *) Add a bunch of functions that should simplify the creation of 
     X509_NAME structures. Now you should be able to do:
     X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
     and have it automatically work out the correct field type and fill in
     the structures. The more adventurous can try:
     X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
     and it will (hopefully) work out the correct multibyte encoding.
     [Steve Henson]

  *) Change the 'req' utility to use the new field handling and multibyte
     copy routines. Before the DN field creation was handled in an ad hoc
     way in req, ca, and x509 which was rather broken and didn't support
     BMPStrings or UTF8Strings. Since some software doesn't implement
     BMPStrings or UTF8Strings yet, they can be enabled using the config file
     using the dirstring_type option. See the new comment in the default
     openssl.cnf for more info.

       Access to the large state is not always serializable because

  *) New function ASN1_mbstring_copy() this copies a string in either
     ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
     into an ASN1_STRING type. A mask of permissible types is passed
     and it chooses the "minimal" type to use or an error if not type
     is suitable.

  *) Add function equivalents to the various macros in asn1.h. The old

  *) Fix for base64 decode bug. When a base64 bio reads only one line of
     data and it contains EOF it will end up returning an error. This is
     caused by input 46 bytes long. The cause is due to the way base64
     BIOs find the start of base64 encoded data. They do this by trying a
     trial decode on each line until they find one that works. When they
     do a flag is set and it starts again knowing it can pass all the
     data directly through the decoder. Unfortunately it doesn't reset
     the context it uses. This means that if EOF is reached an attempt
     is made to pass two EOFs through the context and this causes the
     resulting error. This can also cause other problems as well. As is
     usual with these problems it takes *ages* to find and the fix is

  *) Ugly workaround to get s_client and s_server working under Windows. The
     old code wouldn't work because it needed to select() on sockets and the
     tty (for keypresses and to see if data could be written). Win32 only
     supports select() on sockets so we select() with a 1s timeout on the
     sockets and then see if any characters are waiting to be read, if none
     are present then we retry, we also assume we can always write data to
     the tty. This isn't nice because the code then blocks until we've
     received a complete line of data and it is effectively polling the
     keyboard at 1s intervals: however it's quite a bit better than not
     working at all :-) A dedicated Windows application might handle this
     with an event loop for example.

838 839 840 841 842 843 844 845 846 847 848
  *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
     and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
     will be called when RSA_sign() and RSA_verify() are used. This is useful
     if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
     For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
     should *not* be used: RSA_sign() and RSA_verify() must be used instead.
     This necessitated the support of an extra signature type NID_md5_sha1
     for SSL signatures and modifications to the SSL library to use it instead
     of calling RSA_public_decrypt() and RSA_private_encrypt().
     [Steve Henson]

849 850 851
  *) Add new -verify -CAfile and -CApath options to the crl program, these
     will lookup a CRL issuers certificate and verify the signature in a
     similar way to the verify program. Tidy up the crl program so it
852
     no longer accesses structures directly. Make the ASN1 CRL parsing a bit
853 854 855 856
     less strict. It will now permit CRL extensions even if it is not
     a V2 CRL: this will allow it to tolerate some broken CRLs.
     [Steve Henson]

857 858 859 860 861
  *) Initialize all non-automatic variables each time one of the openssl
     sub-programs is started (this is necessary as they may be started
     multiple times from the "OpenSSL>" prompt).
     [Lennart Bang, Bodo Moeller]

862 863 864 865 866 867 868
  *) Preliminary compilation option RSA_NULL which disables RSA crypto without
     removing all other RSA functionality (this is what NO_RSA does). This
     is so (for example) those in the US can disable those operations covered
     by the RSA patent while allowing storage and parsing of RSA keys and RSA
     key generation.

873 874 875 876

     ASCII string. This was handled independently in various places before.
     [Steve Henson]

877 878 879 880

     UTF8 strings a character at a time.

881 882 883 884 885
  *) Use client_version from client hello to select the protocol

886 887 888 889 890 891 892
  *) Add various utility functions to handle SPKACs, these were previously
     handled by poking round in the structure internals. Added new function
     NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
     print, verify and generate SPKACs. Based on an original idea from
     Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.

896 897 898 899 900 901 902 903
  *) Allow the config file extension section to be overwritten on the
     command line. Based on an original idea from Massimiliano Pala
     <madwolf@comune.modena.it>. The new option is called -extensions
     and can be applied to ca, req and x509. Also -reqexts to override
     the request extensions in req and -crlexts to override the crl extensions
     in ca.
     [Steve Henson]

904 905 906 907 908 909 910
  *) Add new feature to the SPKAC handling in ca.  Now you can include
     the same field multiple times by preceding it by "XXXX." for example:
     1.OU="Unit name 1"
     2.OU="Unit name 2"
     this is the same syntax as used in the req config file.
     [Steve Henson]

911 912 913 914 915 916
  *) Allow certificate extensions to be added to certificate requests. These
     are specified in a 'req_extensions' option of the req section of the
     config file. They can be printed out with the -text option to req but
     are otherwise ignored at present.
     [Steve Henson]

917
  *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
918
     data read consists of only the final block it would not decrypted because
919 920 921 922 923
     EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
     A misplaced 'break' also meant the decrypted final block might not be
     copied until the next read.
     [Steve Henson]

924 925 926 927 928
  *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
     a few extra parameters to the DH structure: these will be useful if
     for example we want the value of 'q' or implement X9.42 DH.
     [Steve Henson]

929 930 931 932 933 934 935 936
  *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
     provides hooks that allow the default DSA functions or functions on a
     "per key" basis to be replaced. This allows hardware acceleration and
     hardware key storage to be handled without major modification to the
     library. Also added low level modexp hooks and CRYPTO_EX structure and 
     associated functions.
     [Steve Henson]

937 938 939 940 941 942 943 944 945
  *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
     as "read only": it can't be written to and the buffer it points to will
     not be freed. Reading from a read only BIO is much more efficient than
     a normal memory BIO. This was added because there are several times when
     an area of memory needs to be read from a BIO. The previous method was
     to create a memory BIO and write the data to it, this results in two
     copies of the data and an O(n^2) reading algorithm. There is a new
     function BIO_new_mem_buf() which creates a read only memory BIO from
     an area of memory. Also modified the PKCS#7 routines to use read only
946
     memory BIOs.

949 950 951 952 953 954
  *) Bugfix: ssl23_get_client_hello did not work properly when called in
     state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
     a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
     but a retry condition occured while trying to read the rest.
     [Bodo Moeller]

955 956 957 958 959 960 961 962
  *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
     NID_pkcs7_encrypted by default: this was wrong since this should almost
     always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
     the encrypted data type: this is a more sensible place to put it and it
     allows the PKCS#12 code to be tidied up that duplicated this
     functionality.
     [Steve Henson]

963 964 965 966 967

  *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
     DH parameters/keys (q is lost during that conversion, but the resulting
     DH parameters contain its length).

     For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
     much faster than DH_generate_parameters (which creates parameters
     where p = 2*q + 1), and also the smaller q makes DH computations
     much more efficient (160-bit exponentiation instead of 1024-bit
     exponentiation); so this provides a convenient way to support DHE
     ciphersuites in SSL/TLS servers (see ssl/ssltest.c).  It is of
     utter importance to use
         SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
     or
         SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
     when such DH parameters are used, because otherwise small subgroup
     attacks may become possible!

     an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
     it will always use the numerical form of the OID, even if it has a short
     or long name.
     [Steve Henson]

1020 1021 1022 1023
  *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
     method only got called if p,q,dmp1,dmq1,iqmp components were present,
     otherwise bn_mod_exp was called. In the case of hardware keys for example
     no private key components need be present and it might store extra data
1024 1025 1026
     in the RSA structure, which cannot be accessed from bn_mod_exp.
     By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
     private key operations.

          typedef int pem_password_cb(char *buf, int size, int rwflag);
     to
          ....(char *buf, int size, int rwflag, void *userdata);
     so that applications can pass data to their callbacks:
     The PEM[_ASN1]_{read,write}... functions and macros now take an
     additional void * argument, which is just handed through whenever
     the password callback is called.

     New function SSL_CTX_set_default_passwd_cb_userdata.

     Compatibility note: As many C implementations push function arguments
     onto the stack in reverse order, the new library version is likely to
     interoperate with programs that have been compiled with the old
     pem_password_cb definition (PEM_whatever takes some data that
     happens to be on the stack as its last argument, and the callback
     just ignores this garbage); but there is no guarantee whatsoever that
     this will work.

  *) The x509 application mishandled signing requests containing DSA
     keys when the signing key was also DSA and the parameters didn't match.

     It was supposed to omit the parameters when they matched the signing key:
     the verifying software was then supposed to automatically use the CA's
     parameters if they were absent from the end user certificate.

     Omitting parameters is no longer recommended. The test was also
     the wrong way round! This was probably due to unusual behaviour in
     EVP_cmp_parameters() which returns 1 if the parameters match. 
     This meant that parameters were omitted when they *didn't* match and
     the certificate was useless. Certificates signed with 'ca' didn't have
     this bug.

     "off" is now the default.
     The library internally uses
         CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
         CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
     to disable memory-checking temporarily.

1285 1286 1287 1288 1289 1290 1291 1292 1293 1294 1295
  *) Rewrite the way password based encryption (PBE) is handled. It used to
     assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
     structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
     but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
     the 'parameter' field of the AlgorithmIdentifier is passed to the
     underlying key generation function so it must do its own ASN1 parsing.
     This has also changed the EVP_PBE_CipherInit() function which now has a
     'parameter' argument instead of literal salt and iteration count values
     and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
     [Steve Henson]

1296
  *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
1297 1298 1299 1300 1301
     and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
     Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
     KEY" because this clashed with PKCS#8 unencrypted string. Since this
     value was just used as a "magic string" and not used directly its
     value doesn't matter.

1369 1370 1371 1372 1373 1374 1375 1376 1377 1378 1379 1380
  *) New functions sk_num, sk_value and sk_set to replace the previous macros.
     These are required because of the typesafe stack would otherwise break 
     existing code. If old code used a structure member which used to be STACK
     and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
     sk_num or sk_value it would produce an error because the num, data members
     are not present in STACK_OF. Now it just produces a warning. sk_set
     replaces the old method of assigning a value to sk_value
     (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
     that does this will no longer work (and should use sk_set instead) but
     this could be regarded as a "questionable" behaviour anyway.

  *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
     copying pointers.  The cert_st handling is changed by this in
     various ways (and thus what used to be known as ctx->default_cert
     is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
     any longer when s->cert does not give us what we need).
     ssl_cert_instantiate becomes obsolete by this change.
     As soon as we've got the new code right (possibly it already is?),
     we have solved a couple of bugs of the earlier code where s->cert
     was used as if it could not have been shared with other SSL structures.

     Note that using the SSL API in certain dirty ways now will result
     in different behaviour than observed with earlier library versions:
     Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
     does not influence s as it used to.
     
     In order to clean up things more thoroughly, inside SSL_SESSION
1454 1455 1456 1457 1458
     we don't use CERT any longer, but a new structure SESS_CERT
     that holds per-session data (if available); currently, this is
     the peer's certificate chain and, for clients, the server's certificate
     and temporary key.  CERT holds only those values that can have
     meaningful defaults in an SSL_CTX.

     read the ANSI prototypes in all header files (thus the old K&R definitions
     aren't needed for error creation any more) and do a better job of
     translating function codes into names. The old 'ASN1 error code imbedded
     in a comment' is no longer necessary and it doesn't use .err files which
1576 1577

  *) Introduce type-safe STACKs. This will almost certainly break lots of code
     that links with OpenSSL (well at least cause lots of warnings), but fear
     not: the conversion is trivial, and it eliminates loads of evil casts. A
     few STACKed things have been converted already. Feel free to convert more.
     In the fullness of time, I'll do away with the STACK type altogether.
     [Ben Laurie]

1674 1675 1676 1677 1678 1679
  *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
     specified in <certfile> by updating the entry in the index.txt file.
     This way one no longer has to edit the index.txt file manually for
     revoking a certificate. The -revoke option does the gory details now.

     doesn't work when the session is reused. Coming soon!
     [Ben Laurie]

  *) Fix a security hole, that allows sessions to be reused in the wrong
     context thus bypassing client cert protection! All software that uses
     client certs and session caches in multiple contexts NEEDS PATCHING to
     allow session reuse! A fuller solution is in the works.

     [Ben Laurie]

1800 1801 1802 1803 1804 1805
  *) Change the meaning of 'ALL' in the cipher list. It now means "everything
     except NULL ciphers". This means the default cipher list will no longer
     enable NULL ciphers. They need to be specifically enabled e.g. with
     the string "DEFAULT:eNULL".
     [Steve Henson]

1806 1807 1808 1809 1810
  *) Fix to RSA private encryption routines: if p < q then it would
     occasionally produce an invalid result. This will only happen with
     externally generated keys because OpenSSL (and SSLeay) ensure p > q.
     [Steve Henson]

1811 1812 1813 1814 1815 1816 1817
  *) Be less restrictive and allow also `perl util/perlpath.pl
     /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
     because this way one can also use an interpreter named `perl5' (which is
     usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
     installed as `perl').
     [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]

1818 1819 1820

1821 1822 1823
  *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
     advapi32.lib to Win32 build and change the pem test comparision
     to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
1824 1825 1826

     is horrible: I feel ill....
     [Steve Henson]

1836 1837 1838 1839
  *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
     in e_os.h. Audit of header files to check ANSI and non ANSI
     sections: 10 functions were absent from non ANSI section and not exported
     from Windows DLLs. Fixed up libeay.num for new functions.

  *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
     fine under Unix and passes some trivial tests I've now added. But the
     whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
     added to make sure no one expects that this stuff really works in the
     OpenSSL 0.9.2 release.  Additionally I've started to clean the XS sources
     up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
     openssl_bio.xs.

1873 1874 1875 1876 1877 1878 1879 1880 1881 1882 1883 1884
  *) Add a useful kludge to allow package maintainers to specify compiler and
     other platforms details on the command line without having to patch the
     Configure script everytime: One now can use ``perl Configure
     <id>:<details>'', i.e. platform ids are allowed to have details appended
     to them (seperated by colons). This is treated as there would be a static
     pre-configured entry in Configure's %table under key <id> with value
     <details> and ``perl Configure <id>'' is called.  So, when you want to
     perform a quick test-compile under FreeBSD 3.1 with pgcc and without
     assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
     now, which overrides the FreeBSD-elf entry on-the-fly.

     [Ben Laurie]

1888 1889 1890 1891 1892 1893
  *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
     on the `perl Configure ...' command line. This way one can compile
     OpenSSL libraries with Position Independent Code (PIC) which is needed
     for linking it into DSOs.

     Fixed.

1898 1899 1900 1901 1902 1903 1904
  *) Cleaned up the LICENSE document: The official contact for any license
     questions now is the OpenSSL core team under openssl-core@openssl.org.
     And add a paragraph about the dual-license situation to make sure people
     recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
     to the OpenSSL toolkit.
     [Ralf S. Engelschall]

1905 1906 1907 1908 1909 1910 1911 1912
  *) General source tree makefile cleanups: Made `making xxx in yyy...'
     display consistent in the source tree and replaced `/bin/rm' by `rm'.
     Additonally cleaned up the `make links' target: Remove unnecessary
     semicolons, subsequent redundant removes, inline point.sh into mklink.sh
     to speed processing and no longer clutter the display with confusing
     stuff. Instead only the actually done links are displayed.
     [Ralf S. Engelschall]

Ben Laurie 已提交
1913 1914 1915 1916 1917 1918
  *) Permit null encryption ciphersuites, used for authentication only. It used
     to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
     It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
     encryption.
     [Ben Laurie]

1919 1920 1921 1922 1923 1924
  *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
     signed attributes when verifying signatures (this would break them), 
     the detached data encoding was wrong and public keys obtained using
     X509_get_pubkey() weren't freed.
     [Steve Henson]

1925 1926 1927 1928 1929 1930
  *) Add text documentation for the BUFFER functions. Also added a work around
     to a Win95 console bug. This was triggered by the password read stuff: the
     last character typed gets carried over to the next fread(). If you were 
     generating a new cert request using 'req' for example then the last
     character of the passphrase would be CR which would then enter the first
     field as blank.
1931 1932
     [Steve Henson]

1933 1934 1935 1936 1937 1938
  *) Added the new `Includes OpenSSL Cryptography Software' button as
     doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
     button and can be used by applications based on OpenSSL to show the
     relationship to the OpenSSL project.  
     [Ralf S. Engelschall]

1939 1940 1941 1942
  *) Remove confusing variables in function signatures in files
     ssl/ssl_lib.c and ssl/ssl.h.
     [Lennart Bong <lob@kulthea.stacken.kth.se>]

1943 1944 1945

     [Lennart Bong <lob@kulthea.stacken.kth.se>]

1946 1947 1948 1949 1950 1951 1952
  *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
     functions that return function pointers and has support for NT specific
     stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
     #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
     unsigned to signed types: this was killing the Win32 compile.
     [Steve Henson]

1953 1954 1955 1956 1957
  *) Add new certificate file to stack functions,
     SSL_add_dir_cert_subjects_to_stack() and
     SSL_add_file_cert_subjects_to_stack().  These largely supplant
     SSL_load_client_CA_file(), and can be used to add multiple certs easily
     to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1958 1959 1960 1961
     This means that Apache-SSL and similar packages don't have to mess around
     to add as many CAs as they want to the preferred list.
     [Ben Laurie]

1962 1963 1964 1965 1966
  *) Experiment with doxygen documentation. Currently only partially applied to
     ssl/ssl_lib.c.
     See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
     openssl.doxy as the configuration file.
     [Ben Laurie]
1967 1968 1969
  
  *) Get rid of remaining C++-style comments which strict C compilers hate.
     [Ralf S. Engelschall, pointed out by Carlos Amengual]
1970

1971 1972 1973 1974
  *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
     compiled in by default: it has problems with large keys.
     [Steve Henson]

1975 1976 1977 1978 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992
  *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
     DH private keys and/or callback functions which directly correspond to
     their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
     is needed for applications which have to configure certificates on a
     per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
     (e.g. s_server). 
        For the RSA certificate situation is makes no difference, but
     for the DSA certificate situation this fixes the "no shared cipher"
     problem where the OpenSSL cipher selection procedure failed because the
     temporary keys were not overtaken from the context and the API provided
     no way to reconfigure them. 
        The new functions now let applications reconfigure the stuff and they
     are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
     SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback.  Additionally a new
     non-public-API function ssl_cert_instantiate() is used as a helper
     function and also to reduce code redundancy inside ssl_rsa.c.
     [Ralf S. Engelschall]

1993 1994 1995 1996 1997
  *) Move s_server -dcert and -dkey options out of the undocumented feature
     area because they are useful for the DSA situation and should be
     recognized by the users.
     [Ralf S. Engelschall]

1998 1999 2000 2001 2002 2003
  *) Fix the cipher decision scheme for export ciphers: the export bits are
     *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
     SSL_EXP_MASK.  So, the original variable has to be used instead of the
     already masked variable.

2007 2008 2009 2010 2011
  *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
     from `int' to `unsigned int' because it's a length and initialized by

2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026
  *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
     (in addition to RSA certificates) to match the behaviour of `openssl dsa
     -noout -modulus' as it's already the case for `openssl rsa -noout
     -modulus'.  For RSA the -modulus is the real "modulus" while for DSA
     currently the public key is printed (a decision which was already done by
     `openssl dsa -modulus' in the past) which serves a similar purpose.
     Additionally the NO_RSA no longer completely removes the whole -modulus
     option; it now only avoids using the RSA stuff. Same applies to NO_DSA
     now, too.

  *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
     padding method for RSA, which is recommended for new applications in PKCS
     #1 v2.0 (RFC 2437, October 1998).
     OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
     foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
     against Bleichbacher's attack on RSA.

  *) Updates to the new SSL compression code
     [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]

  *) Fix so that the version number in the master secret, when passed
     via RSA, checks that if TLS was proposed, but we roll back to SSLv3
     (because the server will not accept higher), that the version number
     is 0x03,0x01, not 0x03,0x00

2080 2081
  *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory

2094 2095 2096 2097 2098 2099

     update to the INSTALL.W32 file with (hopefully) more accurate Win32
     build instructions.

2100 2101 2102 2103 2104 2105
  *) Modify configure script 'Configure' to automatically create crypto/date.h
     file under Win32 and also build pem.h from pem.org. New script
     util/mkfiles.pl to create the MINFO file on environments that can't do a
     'make files': perl util/mkfiles.pl >MINFO should work.
     [Steve Henson]

2106 2107 2108 2109 2110 2111
  *) Major rework of DES function declarations, in the pursuit of correctness
     and purity. As a result, many evil casts evaporated, and some weirdness,
     too. You may find this causes warnings in your code. Zapping your evil
     casts will probably fix them. Mostly.
     [Ben Laurie]

2112 2113 2114 2115 2116 2117
  *) Fix for a typo in asn1.h. Bug fix to object creation script
     obj_dat.pl. It considered a zero in an object definition to mean
     "end of object": none of the objects in objects.h have any zeros
     so it wasn't spotted.

2128 2129 2130 2131 2132 2133 2134
  *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
     message is now correct (it understands "crypto" and "ssl" on its
     command line). There is also now an "update" option. This will update
     the util/ssleay.num and util/libeay.num files with any new functions.

  *) Overhauled the Perl interface (perl/*):
     - ported BN stuff to OpenSSL's different BN library
     - made the perl/ source tree CVS-aware
     - renamed the package from SSLeay to OpenSSL (the files still contain
       their history because I've copied them in the repository)

  *) First cut for a very conservative source tree cleanup:
     1. merge various obsolete readme texts into doc/ssleay.txt
     where we collect the old documents and readme texts.
     2. remove the first part of files where I'm already sure that we no
     longer need them because of three reasons: either they are just temporary
     files which were left by Eric or they are preserved original files where
     I've verified that the diff is also available in the CVS via "cvs diff
     -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
     the crypto/md/ stuff).
     [Ralf S. Engelschall]

2157 2158 2159 2160 2161 2162 2163
  *) More extension code. Incomplete support for subject and issuer alt
     name, issuer and authority key id. Change the i2v function parameters
     and add an extra 'crl' parameter in the X509V3_CTX structure: guess
     what that's for :-) Fix to ASN1 macro which messed up
     IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
     [Steve Henson]

2164 2165 2166 2167
  *) Preliminary support for ENUMERATED type. This is largely copied from the

2191 2192 2193 2194 2195

     but the BN code had some problems that would cause failures when
     doing certificate verification and some other functions.
     [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]

2196 2197 2198

2209 2210 2211 2212 2213
  *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
     and add a sample to openssl.cnf so req -x509 now adds appropriate
     CA extensions.
     [Steve Henson]

2214 2215
  *) Continued X509 V3 changes. Add to other makefiles, integrate with the
     error code, add initial support to X509_print() and x509 application.

     [Steve Henson]
2217

2218 2219 2220 2221 2222
  *) Takes a deep breath and start addding X509 V3 extension support code. Add
     files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
     stuff is currently isolated and isn't even compiled yet.
     [Steve Henson]

2223 2224 2225 2226 2227 2228 2229
  *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
     ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
     Removed the versions check from X509 routines when loading extensions:
     this allows certain broken certificates that don't set the version
     properly to be processed.

2230 2231 2232 2233 2234

2238 2239 2240 2241 2242 2243 2244 2245 2246
  *) Changes to the error generation code. The perl script err-code.pl 
     now reads in the old error codes and retains the old numbers, only
     adding new ones if necessary. It also only changes the .err files if new
     codes are added. The makefiles have been modified to only insert errors
     when needed (to avoid needlessly modifying header files). This is done
     by only inserting errors if the .err file is newer than the auto generated
     C file. To rebuild all the error codes from scratch (the old behaviour)
     either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
     or delete all the .err files.

     based on a text string, looking up short and long names and finally
     "dot" format. The "dot" format stuff didn't work. Added new function
     OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
