Here's a real-life brainteaser for you!
I have a large number of passwords nowadays, many of which I very rarely use so I can't remember them myself. I don't like to use a software password manager, so I keep them all written in a text file on my pc - all encrypted of course. The code I use is fairly simple though, just something I thought up in 10 seconds, and I was slightly disturbed to see how quickly a mate of mine guessed the principle it was based on, although he didn't crack it completely.
I'm interested to know how quickly it can be cracked with a moderate amount of effort from an intelligent non-expert. So here's a sample of my password file - go to it! The first person to crack them wins respect and a pat on the back.
NB: Obviously, I'm not telling you what these passwords are for, or what the usernames to go with them are. They don't include passwords for accounts where you will be able to get credit card details, access my email etc, and they don't include my physicsforums.com password - they're just the boring accounts which I'd be willing to risk losing
