gnutls_x509_crt_get_verify_algorithm(3)

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
