NAME

gnutls_x509_crt_verify_data2 - API function

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crt_verify_data2(gnutls_x509_crt_t crt, gnutls_sign_algorithm_t algo, unsigned int flags, const gnutls_datum_t * data, const gnutls_datum_t * signature);

ARGUMENTS

gnutls_x509_crt_t crt: Holds the certificate to verify with
gnutls_sign_algorithm_t algo: The signature algorithm used
unsigned int flags: Zero or an OR list of gnutls_certificate_verify_flags
const gnutls_datum_t * data: holds the signed data
const gnutls_datum_t * signature: contains the signature

DESCRIPTION

This function will verify the given signed data, using the parameters from the certificate.

RETURNS

In case of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED is returned, GNUTLS_E_EXPIRED or GNUTLS_E_NOT_YET_ACTIVATED on expired or not yet activated certificate and zero or positive code on success.

Note that since GnuTLS 3.5.6 this function introduces checks in the end certificate ( crt ), including time checks and key usage checks.

SINCE

3.4.0
