Can i use this Ci Starter. Is it safe?

1. GibberishAES is a 3 years old class. By the time I created it there was no CI_Encryption library. The next weekend I will go through your thoughts about it.

2. "That's an improvement, I'll give you that ... but if it's called "Password", then encrypt/decrypt methods simply don't belong in it. People make bad decisions every time you give them the chance to, and as I said - that's very dangerous when it comes to security." - I accept this. What I need actually is encrypted settings within the database, so this kind of functionality belongs to the Settings library and will be moved there.
