The sodium key should be 32

[peter279k]

This is about the quick fix for Sodium key size.

And we consider the following code snippets in SodiumEncryption class:

....
public function __construct($key = null)
    {
        if (!function_exists('sodium_crypto_secretbox_keygen')) {
            throw new \Exception('The sodium php extension does not installed or enabled', 500);
        }

        if (null !== $key) {

            //Should use user define key.
            $this->key = substr(hash('sha512', $key), 0, 32);
        } else {
            throw new \Exception('Crypto key not found', 500);
        }
    }
......

This will not validate the $key size length in this class constructor.

We need to do this validation to mention the developers the key size is invalid.

And key size should be 32.
