Is there an Encryption class? What am I missing?

@Leo - what are using encryption for? I've almost never used that library myself so trying to understand use cases.

Hi Kilishan, this is a good point, one such use for encryption, well a practical one, is say storing a SMTP password, encrypting it storing it in the database and then decrypting it to use again for email transport.

This means if a hacker got your database, they would also need the encryption key as well to uncover the SMTP password which is stored in the config file. I think it is a two layer safety net. They would need to hack your db and get access to your server code.
