For a similar problem in my CA code (See RAA) I used an alphabet

class Password
   ALPHABET='qwertyQWERTY123456'

   SHORT=6
   MEDIUM=12
   LONG=18

   def Password.create(length=8, strength=MEDIUM)
     password = ''

     (0...length).times { password << ALPHABET[rand(strength)] }

     return password
   end
end

Warning, untested code!

You get the idea.
