=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)> 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.
|
|
|
|
Note: SSL_get_ciphers() and SSL_get_client_ciphers() return a pointer
|
|
to an internal cipher stack, which will be freed later on when the SSL
|
|
or SSL_SESSION object is freed. Therefore, the calling code B<MUST
|
|
NOT> free the return value itself.
