gnutls_pubkey_verify_hash23
Api function
Usage
#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 |
const gnutls_datum_t * hash
|
holds the hash digest to be verified |
const gnutls_datum_t * signature
|
contains the signature |
Overview
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. For known to be insecure signatures this function will return GNUTLS_E_INSUFFICIENT_SECURITY unless the flag GNUTLS_VERIFY_ALLOW_BROKEN is specified.
