I've got an encrypted USB drive and I want to check I know the password. At the moment everything is in my keychain, so it works, and I can see its contents, but I want to make sure I'm covered if I need to replace my computer.
I want to make sure I can keep the contents if it turns out I've forgotten the password, so I don't want to delete any data from the keychain. (If I've forgotten the password, I'll need to copy its contents off before reformatting it.)
How do I do this?
