gnutls_cipher_suite_info - Man Page

API function


#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 * min_version);


size_t idx

index of cipher suite to get information about, starts on 0.

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 NULL.

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.


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.


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.
