NAME         top

       gnutls_x509_crt_verify_data2 - API function

SYNOPSIS         top

       #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         top

       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         top

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

RETURNS         top

       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         top

       3.4.0
