Diceware

# -*- 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!

    while (line = file.gets)
      if line.chomp.encode("UTF-8").valid_encoding?
        words << line.chomp.encode("UTF-8").split('\W')
      end
    end
    puts "read "+wordlist_path+"/"+name
    file.close
  end
end

puts "words: #{words.length}"

100.times{
  puts words[SecureRandom.random_number(words.length)]
