Synopsis:
#include <qcrypto/qcrypto.h>
int qcrypto_signature_verify_oneshot(qcrypto_ctx_t *ctx,
const uint8_t *data,
size_t size,
const uint8_t *sig,
size_t sigsize,
int *status)
Arguments:
- ctx
- The algorithm context object.
- data
- The input data.
- size
- The input data size.
- sig
- The signature buffer.
- sigsize
- The signature buffer size.
- status
- The verification result.
Library:
libqcryptoDescription:
This function combines qcrypto_signature_update() and qcrypto_signature_verify() in one operation for cases where the data size is known in advance, is small enough that it can be passed in a single operation, or both.
Returns:
QCRYPTO_R_EOK if successful or qcrypto_errno
if an error occurred.
