Description: Class source
Class: PHP Sodium Compat
Cryptographic functions of libsodium in pure PHP
Author: By
Last change: Stricter typing
Set minimum PHP version to 8.1 for v2.x
Add type checks at runtime
Remove type declarations

There's no way to make them nullable in PHP 5, so it's our only way forward.

I _could_ add runtime type checks, but why bother?
