gnutls_pubkey_verify_hash2(3) gnutls gnutls_pubkey_verify_hash2(3)
gnutls_pubkey_verify_hash2 - API function
#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);
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
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.
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.
