=head1 NAME

SSL_get_current_cipher, SSL_get_cipher, SSL_get_cipher_name,
SSL_get_cipher_bits, SSL_get_cipher_version - get SSL_CIPHER of a connection

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 SSL_CIPHER *SSL_get_current_cipher(const SSL *ssl);
 #define SSL_get_cipher(s) \
                SSL_CIPHER_get_name(SSL_get_current_cipher(s))
 #define SSL_get_cipher_name(s) \
                SSL_CIPHER_get_name(SSL_get_current_cipher(s))
 #define SSL_get_cipher_bits(s,np) \
                SSL_CIPHER_get_bits(SSL_get_current_cipher(s),np)
 #define SSL_get_cipher_version(s) \
                SSL_CIPHER_get_version(SSL_get_current_cipher(s))

=head1 DESCRIPTION

SSL_get_current_cipher() returns a pointer to an SSL_CIPHER object containing
the description of the actually used cipher of a connection established with
the B<ssl> object.

SSL_get_cipher() and SSL_get_cipher_name() are identical macros to obtain the
name of the currently used cipher. SSL_get_cipher_bits() is a
macro to obtain the number of secret/algorithm bits used and 
SSL_get_cipher_version() returns the protocol name.
See L<SSL_CIPHER_get_name(3)> for more details.

=head1 RETURN VALUES

SSL_get_current_cipher() returns the cipher actually used or NULL, when
no session has been established.
