The class SilverStripe\HybridSessions\Crypto\McryptCrypto has been deprecated with message: 2.2.0 The PHP mcrypt library is deprecated. Please use OpenSSLCrypto instead. WARNING: Please beware that McryptCrypto does not preserve zero bytes at the end of encrypted messages. Thus, a message such as "data\x00" will become "data" after encrypt-decrypt. As such, it is not binary safe. It is guaranteed for UTF-8 encoded text not to have zero bytes. However, other encodings may contain those. For example, be careful with UTF-16LE, since characters less than U+0100 are very common.
