NAME
SSL_get_ciphers,
SSL_get_cipher_list —
get list of available
SSL_CIPHERs
SYNOPSIS
#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);
DESCRIPTION
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_ciphers()
returns a pointer to an internal cipher stack, which will be freed later on
when the SSL object is freed. Therefore, the calling
code must not free the return value itself.
The details of the ciphers obtained by
SSL_get_ciphers()
can be obtained using the
SSL_CIPHER_get_name(3) family of functions.
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 fewer ciphers than priority
available, NULL is returned.
Call
SSL_get_cipher_list()
with priority starting from 0 to obtain the sorted
list of available ciphers, until NULL is
returned.
