NAME

       gnutls_pubkey_verify_hash2 - API function

SYNOPSIS

       #include <gnutls/abstract.h>

       int  gnutls_pubkey_verify_hash2(gnutls_pubkey_t  key,  gnutls_sign_algorithm_t  algo, unsigned int flags,
       const gnutls_datum_t * hash, const gnutls_datum_t * signature);

ARGUMENTS

       gnutls_pubkey_t key
                   Holds the public key

       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 * hash
                   holds the hash digest to be verified

       const gnutls_datum_t * signature
                   contains the signature

DESCRIPTION

       This function will verify the given signed digest, using the parameters from the public  key.  Note  that
       unlike  gnutls_privkey_sign_hash(),  this  function  accepts  a  signature  algorithm instead of a digest
       algorithm.  You can use gnutls_pk_to_sign() to get the appropriate value.

RETURNS

       In case of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED is returned, and zero or positive code on
       success.

SINCE

       3.0
