Huh? That's not correct. You can still introduce entropy into the random pool by writing to /dev/urandom or /dev/random. It is true that there has been some changes to the design of /dev/random, but I assure you as the original /dev/random developer, was consulted and involved in the design discussions. Anyway, this is off-topic for TUHS, but if you have specific questions/complaints, feel free to address them to me and Jason. Your comments do make me suspect that there are some fundamental misunderstandings at work. Cheers, - Ted
