The existing method to obtain the name of the currently negotiated TLS ciphersuite is as follows:
- call gnutls_cipher_get, gnutls_mac_get, gnutls_kx_get
- call gnutls_cipher_suite_get_name with the value from the above functions
This process is cumbersome and only works with TLS 1.2 or earlier; moreover the returned names are GnuTLS specific.
This change adds a new function gnutls_ciphersuite_get to eliminate those limitations. It returns the "canonical" name of the ciphersuite, which is mostly identical to the ones registered in IANA, with an exception for compatibility.
