[OT] Passwords Question

[Chuck Esterbrook]

Well this really isn't a programming topic, but I bet the folks on
this list have good and/or interesting answers for this question,
so...

I maintain a file with account names and passwords. For security, I've
been using a password-protected Microsoft Excel file.

What if I want to move this over to a Unix-like system? A plain text
file is obviously unacceptable and I don't want to use a GUI app like
OpenOffice or such.
