qcrypto_kdf_generate()

Generate a symmetric key via KDF

Synopsis:

#include <qcrypto/qcrypto.h>

int qcrypto_kdf_generate(qcrypto_ctx_t *ctx,
                         qcrypto_key_t **key,
                         size_t keysize,
                         const qcrypto_kdf_args_t *kdfargs,
                         qcrypto_ctx_t **keyctx)

Arguments:

ctx: The algorithm context object.
key: The generated key handle.
keysize: The key size to generate.
kdfargs: The KDF parameters.
keyctx: The algorithm context object that manipulates the resulting key, if required (optional).

Library:

Description:

This function generates a symmetric key based on the specified input data. See also qcrypto_kdf_args_t.

Returns:

QCRYPTO_R_EOK if successful or qcrypto_errno if an error occurred.
