NAME
       gnutls_x509_crt_get_verify_algorithm - get hash algorithm used to verify signature.

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_verify_algorithm(gnutls_x509_crt_t crt, const gnutls_datum_t * signature, gnutls_digest_algorithm_t * hash);

ARGUMENTS
       gnutls_x509_crt_t crt
		   Holds the certificate

       const gnutls_datum_t * signature
		   contains the signature

       gnutls_digest_algorithm_t * hash
		   The result of the call with the hash algorithm used for signature

DESCRIPTION
       This function will read the certifcate and the signed data to determine the hash algorithm used to generate the signature.

RETURNS
       the 0 if the hash algorithm is found. A negative value is returned on error.

SINCE
       2.8.0
