Probably worth noting here...You can always create your own stream of pseudorandom bytes. No comment on quality. dd bs=1M count=1024 if=/dev/zero|openssl enc -bf-cbc -pass file:/dev/urandom Goes 12x faster than urandom on my box. (Better to use a 128bit blocksize perhaps, but bf is fast:) On 9/2/06, Andreas Grassl <andog@xxxxxxx> wrote:
