Answer 1

As mentioned above, you should first look into the legality of this, especially with Apple restrictions on what goes in the app store.

That said, I have had to encrypt sensitive information before, and decided to go overboard with AES-256 encryption. Since usernames, passwords and personal data were being sent over a network, it was necessary. I used FBEncrypt for this - it's a great wrapper around CCCrypt.

That will allow you to do base-64 encoding and AES-256 encoding, among other things, and it is really convenient. Check it out if you really need it!
