Is there a module that will read a file with random letters off of a floppy disk, MD5 it, and compare it to an md5sum on the hard drive, possibly stuck in the passwd file, as an alternative to entering passwords repeatedly? Passwords are annoying to type in, and any password I can think up and remember is easy to break (though not really a threat in the home environment).

And yes, I know it's easier to find a floppy then try to break an easy password manually by unskilled computer users who don't know about password breaking utils. I just hate typing stuff repeatedly.

There should be some sort of method where you store a secure key on some sort of removable storage medium (flash, floppy, CD), authenticating off of that.
