Synopsis:

#include <qcrypto/qcrypto_keys.h>
int qcrypto_key_to_mem(qcrypto_ctx_t *ctx,
                       qcrypto_key_t *key,
                       uint8_t *kbuf,
                       size_t *ksize)

Arguments:

ctx
The algorithm context object.
key
The symmetric key handle.
kbuf
The key buffer. To return the actual key size in ksize, specify NULL.
ksize
The size of the provided key buffer. Must be at least as large as the key. The actual key size is returned in ksize if the call is successful.
