Wir basteln einen haltbaren Sonnenfilter

# -*- coding: undecided -*-
# Simple Diceware tool for creating passwords.
#
# This tool takes all words in /usr/share/dict and randomly selects some of them using the Ruby securerandom class. Sadly this class uses only a PRNG and not /dev/random. Be warned!
