gnutls_pubkey_verify_hash2 - API function

Синопсис (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);

Аргументы (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

Описание (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.

Возвращаемое значение (Return value)

In case of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED
       is returned, and zero or positive code on success. For known to
       be insecure signatures this function will return
       GNUTLS_E_INSUFFICIENT_SECURITY unless the flag
       GNUTLS_VERIFY_ALLOW_BROKEN is specified.
