Does it matter what string you actually pass to your system call? If not you
could try passing the user's string through md5 and then
base64.encodestring:
>>> print base64.encodestring(md5.md5('$|\n').digest())[:-3]

The process isn't reversible, but since you refer to using the strings as
passwords this may not matter.
