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_al-
gorithm_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 re-
turned, 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
