5 SSL_get_ciphers, SSL_get_cipher_list - get list of available SSL_CIPHERs

11 STACK_OF(SSL_CIPHER) *SSL_get_ciphers(const SSL *ssl);
12 STACK_OF(SSL_CIPHER) *SSL_get_client_ciphers(const SSL *ssl);
13 const char *SSL_get_cipher_list(const SSL *ssl, int priority);
17 SSL_get_ciphers() returns the stack of available SSL_CIPHERs for B<ssl>,
18 sorted by preference. If B<ssl> is NULL or no ciphers are available, NULL
21 SSL_get_client_ciphers() returns the stack of available SSL_CIPHERS matching the
22 list sent by the client for B<ssl>. If B<ssl> is NULL, no ciphers are
23 available, or B<ssl> is not operating in server mode, NULL is returned.
25 SSL_get_cipher_list() returns a pointer to the name of the SSL_CIPHER
26 listed for B<ssl> with B<priority>. If B<ssl> is NULL, no ciphers are
27 available, or there are less ciphers than B<priority> available, NULL
32 The details of the ciphers obtained by SSL_get_ciphers() can be obtained using
33 the L<SSL_CIPHER_get_name(3)|SSL_CIPHER_get_name(3)> family of functions.
35 Call SSL_get_cipher_list() with B<priority> starting from 0 to obtain the
36 sorted list of available ciphers, until NULL is returned.
38 Note: SSL_get_ciphers() and SSL_get_client_ciphers() return a pointer
39 to an internal cipher stack, which will be freed later on when the SSL
40 or SSL_SESSION object is freed. Therefore, the calling code B<MUST
41 NOT> free the return value itself.
