@deftypefun {gnutls_digest_algorithm_t} {gnutls_prf_hash_get} (const gnutls_session_t @var{session})
@var{session}: is a @code{gnutls_session_t}  type.

Get the currently used hash algorithm. In TLS 1.3, the hash
algorithm is used for both the key derivation function and
handshake message authentication code. In TLS 1.2, it matches the
hash algorithm used for PRF.

@strong{Returns:} the currently used hash algorithm, a
@code{gnutls_digest_algorithm_t}  value.

@strong{Since:} 3.6.13
