NAME         top

       gnutls_cipher_suite_info - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       const char * gnutls_cipher_suite_info(size_t idx, unsigned char *
       cs_id, gnutls_kx_algorithm_t * kx, gnutls_cipher_algorithm_t *
       cipher, gnutls_mac_algorithm_t * mac, gnutls_protocol_t *

ARGUMENTS         top

       size_t idx  index of cipher suite to get information about, starts on

       unsigned char * cs_id
                   output buffer with room for 2 bytes, indicating cipher
                   suite value

       gnutls_kx_algorithm_t * kx
                   output variable indicating key exchange algorithm, or

       gnutls_cipher_algorithm_t * cipher
                   output variable indicating cipher, or NULL.

       gnutls_mac_algorithm_t * mac
                   output variable indicating MAC algorithm, or NULL.

       gnutls_protocol_t * min_version
                   output variable indicating TLS protocol version, or NULL.

DESCRIPTION         top

       Get information about supported cipher suites.  Use the function
       iteratively to get information about all supported cipher suites.
       Call with idx=0 to get information about first cipher suite, then
       idx=1 and so on until the function returns NULL.

RETURNS         top

       the name of  idx cipher suite, and set the information about the
       cipher suite in the output variables.  If  idx is out of bounds, NULL
       is returned.
