to minimise the effects on existing code.

the secret key before we've encrypted it and using the right NID for RC2-64.
Add various arguments to the experimental programs 'dec' and 'enc' to make
testing less painful.

This stuff has now been tested against Netscape Messenger and it can encrypt
and decrypt S/MIME messages with RC2 (128, 64 and 40 bit) DES and triple DES.

Its still experimental though...

find the right RecipientInfo based on the recipient certificate (so would
fail a lot of the time) and fixup cipher structures to correctly (maybe)
modify the AlgorithmIdentifiers.  Largely untested at present... this will be
fixed in due course. Well the stuff was broken to begin with so if its broken
now then you haven't lost anything :-)

Changed to unsigned int: also need an evil cast in pk7_doit.c because a
signed, unsigned comparison chokes VC++.

detached data encoding was wrong and free up public keys.

under Win32 (9X and NT) again. Note: some signed/unsigned changes recently
checked in were killing the Win32 compile.

from `int' to `unsigned int' because it's a length and initialized by
EVP_DigestFinal() which expects an `unsigned int *'.
