password program

So I need to store a bunch of work-relates passwords (ie everyone's windows passwords) for work. I'm going to put them on paper and keep them in a box somewhere but I'd like ot have reasonably secure software of it somewhere. What I'm thinking of doing is putting them on a good piece of software protection software or splitting the file, encrypting both sides and putting it on two seperate cd's or something.

Anyone have any good advice? Programs that you know of or a better plan of action? Google turns up very little for password protection programs that isn't related to conning people into giving them their windows administrator password. Sad.
