Description détaillée

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.

CAUTION * CAUTION * CAUTION * CAUTION * CAUTION * CAUTION * CAUTION * CAUTION *

Until audited, this is probably not safe to use! DANGER WILL ROBINSON *
