qcrypto_digest()

Initialize, update, and finalize a digest

Synopsis:

#include <qcrypto/qcrypto.h>

int qcrypto_digest(qcrypto_ctx_t *ctx,
                   const uint8_t *data,
                   size_t size,
                   uint8_t *digest,
                   size_t *dsize)

Arguments:

ctx: The algorithm context object.
data: The input data buffer.
size: The size of the input data.
digest: The digest buffer to copy the digest value to. Make sure that the buffer is large enough for the digest.
dsize: A pointer to a variable to store the size of the digest in. Specify NULL if this value is not required.

Library:

libqcrypto

Description:

This function performs qcrypto_digest_init(), qcrypto_digest_update(), and qcrypto_digest_final() in a single operation.

Returns:

QCRYPTO_R_EOK if successful or qcrypto_errno if an error occurred.
