=head1 NAME

SSL_get_ciphers, SSL_get_cipher_list - get list of available SSL_CIPHERs

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 STACK_OF(SSL_CIPHER) *SSL_get_ciphers(const SSL *ssl);
 STACK_OF(SSL_CIPHER) *SSL_get_client_ciphers(const SSL *ssl);
 const char *SSL_get_cipher_list(const SSL *ssl, int priority);

=head1 DESCRIPTION

SSL_get_ciphers() returns the stack of available SSL_CIPHERs for B<ssl>,
sorted by preference. If B<ssl> is NULL or no ciphers are available, NULL
is returned.

SSL_get_client_ciphers() returns the stack of available SSL_CIPHERS matching the
list sent by the client for B<ssl>. If B<ssl> is NULL, no ciphers are
available, or B<ssl> is not operating in server mode, NULL is returned.

SSL_get_cipher_list() returns a pointer to the name of the SSL_CIPHER
listed for B<ssl> with B<priority>. If B<ssl> is NULL, no ciphers are
available, or there are less ciphers than B<priority> available, NULL
is returned.

=head1 NOTES

The details of the ciphers obtained by SSL_get_ciphers() can be obtained using
the L<SSL_CIPHER_get_name(3)|SSL_CIPHER_get_name(3)> family of functions.

Call SSL_get_cipher_list() with B<priority> starting from 0 to obtain the
sorted list of available ciphers, until NULL is returned.
