Answer 1

• Simple iPhone Keychain Code
• Apple: iPhone Keychain Backups
• Is There Any Point To Using The Keychain API On iPhone?

"What you’re left with is an encrypted flat-file database, specialized for just a few data types, with a really clunky and badly documented API. As I wrote above, its functionality could be duplicated, with a better API, without much effort. The encryption part is significant, though, since its primary purpose is to keep keys and passwords safe. A DIY key database could be protected by encrypting it with a symmetric key, and then putting that key in the Keychain."
