SSL_get_ciphers, SSL_get_cipher_list ā€” get list of available SSL_CIPHERs


 #include <openssl/ssl.h>

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


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

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


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

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