@deftypefun {int} {gnutls_x509_crt_verify_data2} (gnutls_x509_crt_t @var{crt}, gnutls_sign_algorithm_t @var{algo}, unsigned int @var{flags}, const gnutls_datum_t * @var{data}, const gnutls_datum_t * @var{signature})
@var{crt}: Holds the certificate to verify with

@var{algo}: The signature algorithm used

@var{flags}: Zero or an OR list of @code{gnutls_certificate_verify_flags} 

@var{data}: holds the signed data

@var{signature}: contains the signature

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

@strong{Returns:} In case of a verification failure @code{GNUTLS_E_PK_SIG_VERIFY_FAILED}  
is returned, and zero or positive code on success.

@strong{Since:} 3.4.0
