gnutls_x509_crt_verify_data2 - API function

#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);*

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

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

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.
