 * Libsodium compatibility layer

 * This is the only class you should be interfacing with, as a user of
 * sodium_compat.
 *
 * If the PHP extension for libsodium is installed, it will always use that
 * instead of our implementations. You get better performance and stronger
 * guarantees against side-channels that way.
 *
 * However, if your users don't have the PHP extension installed, we offer a
 * compatible interface here. It will give you the correct results as if the
 * PHP extension was installed. It won't be as fast, of course.
