@var{pubkey}: Holds the public key

@var{flags}: Zero or one of @code{gnutls_pubkey_flags_t} 

@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.

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. 

@strong{Since:} 2.12.0
