gnutls_pubkey_verify_data2 — API function
Synopsis
#include <gnutls/abstract.h>
int gnutls_pubkey_verify_data2(gnutls_pubkey_t pubkey, gnutls_sign_algorithm_t algo, unsigned int flags, const gnutls_datum_t * data, const gnutls_datum_t * signature);
Arguments
- gnutls_pubkey_t pubkey
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 * data
holds the signed data
- const gnutls_datum_t * signature
contains the signature
Description
This function will verify the given signed data, using the parameters from the certificate.
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.
