NAME
       gnutls_x509_crt_get_verify_algorithm  - get hash algorithm used to ver‐
       ify 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
