Имя (Name)

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.
