- * This API is expected to be applied to a single contiguous region. WARNING:
- * Presently calling this function more than once with "in" pointing to
- * logically different buffers will result in using the same IV value
- * internally and as such reduce encryption efficiency.

- *	       is as defined by CIPHER_SALT_SIZE above.
- *	       WARNING: a given salt/"in" pair must be unique (it is an ERROR
- *	       to use a given salt with more than one unique buffer).  For an
- *	       example, a good salt would be a digest of the plaintext input.
- * @param out Destination pointer where to write plaintext / ciphertext.
- * @param in  Source pointer where to read ciphertext / plaintext.
- * @param len Number of bytes to read from in / write to out.
- * @return non-zero on success, and zero otherwise.
