Was thinking about this as an alternative to existing password managers. The advantage is as you say your passwords aren't stored anywhere, even in encrypted form, and can be retrieved as long as you remember the master key and algorithm, but the disadvantage is that you're essentially sharing a poorly-salted hash of your master password with every service you log in to. I'm going to go for a password manager for now, simply based on my perception that they're widely used by people who know more about security than I do.
