@deftypefun {const gnutls_cipher_algorithm_t *} {gnutls_cipher_list} ( @var{void})
Get a list of supported cipher algorithms. Note that not
necessarily all ciphers are supported as TLS cipher suites. For
example, DES is not supported as a cipher suite, but is supported
for other purposes (e.g., PKCS@code{8} or similar).
This function is not thread safe.
@strong{Returns:} a (0)-terminated list of @code{gnutls_cipher_algorithm_t}
integers indicating the available ciphers.
