@deftypefun {int} {gnutls_x509_crt_verify_data} (gnutls_x509_crt_t @var{crt}, unsigned int @var{flags}, const gnutls_datum_t * @var{data}, const gnutls_datum_t * @var{signature})
@var{crt}: Holds the certificate

@var{flags}: should be 0 for now

@var{data}: holds the data to be signed

@var{signature}: contains the signature

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

Deprecated. This function cannot be easily used securely. 
Use @code{gnutls_pubkey_verify_data2()}  instead.

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