[QUOTE="Robert Klemme, post: 4644968"] My pseudo randomness math is a bit rusty these days but it may be that you do not increase randomness by using your approach as you still use only one source of randomness. If this is the case, the same can be achieved by doing def bytes(n = 16) b = "" n.times { b << rand(256) } b end or with 1.9 def bytes(n = 16) "".tap do |b| n.times { b << rand(256) } end end Kind regards robert [/QUOTE]
