Sign a signature digest
Synopsis:
#include <qcrypto/qcrypto.h>
int qcrypto_signature_sign_nodgst(qcrypto_ctx_t *ctx,
const uint8_t *digest,
size_t size,
uint8_t *sig,
size_t *sigsize)
Arguments:
- ctx
- The algorithm context object.
- digest
- The input digest.
- size
- The input digest size.
- sig
- The signature buffer.
- sigsize
- The combined size of the signature buffer and the retrieved signature.
Library:
libqcryptoDescription:
This function signs the input digest directly. It is used if the digest was calculated externally by another means and replaces qcrypto_signature_update() and qcrypto_signature_sign().
Returns:
QCRYPTO_R_EOK
if successful or qcrypto_errno
if an error occurred.
