I’ve been trying to get my head around cryptography on the iPhone so that I can create a native iPhone app (iPasskeep) that interoperates with my JPasskeep password keeper application. It has taken a while to get my head around CommonCrypto APIs - how to use them, how not to use them and their limitations.

How can I store my list of passwords on an iPhone or iPod Touch? This is the question that I attempted to solve as I geeked out over the weekend. I know I can buy an application like 1Password and sync between a laptop and an iPhone but I already have a pretty good password manager (since I wrote the one I use years ago).

My application for an iPhone was rejected last week. Apparently I am not a good credit risk for O2 even though I can buy the iPhone and a 12 month contract outright.
