Api function

Usage

#include <gnutls/x509.h>

int gnutls_x509_crt_get_signature_algorithm(gnutls_x509_crt_t cert);

Arguments

gnutls_x509_crt_t cert

should contain a gnutls_x509_crt_t type

Overview

This function will return a value of the gnutls_sign_algorithm_t enumeration that is the signature algorithm that has been used to sign this certificate.

Since 3.6.0 this function never returns a negative error code. Error cases and unknown/unsupported signature algorithms are mapped to GNUTLS_SIGN_UNKNOWN.

Returns

a gnutls_sign_algorithm_t value
