=head1 NAME
SSL_get_current_cipher, SSL_get_cipher_name, SSL_get_cipher,
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);
const char *SSL_get_cipher_name(const SSL *s);
const char *SSL_get_cipher(const SSL *s);
int SSL_get_cipher_bits(const SSL *s, int *np) \
const char *SSL_get_cipher_version(const SSL *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.
See L<SSL_CIPHER_get_name(3)> for more details.
SSL_get_cipher_name() obtains the
name of the currently used cipher.
SSL_get_cipher() is identical to SSL_get_cipher_name().
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.
=head1 RETURN VALUES
SSL_get_current_cipher() returns the cipher actually used, or NULL if
no session has been established.
=head1 NOTES
These are implemented as macros.
