(should we move this discussion back to hackers to get a wider > > audience?) There was a long discussion on linux-kernel recently about the difference between 'random' and 'urandom'. The upshot seemed to be that 'urandom' is Good Enough in 99% of the cases, since (as long as the generator is seeded well at startup) attackers would have to break SHA1 in order to predict the output from it. If someone has the resources to do that you're basically screwed anyhow... -Doug -- Free Dmitry Sklyarov! http://www.freesklyarov.org/ We will return to our regularly scheduled signature shortly.
