If /dev/random is blocking due to insufficient entropy, feeding false entropy in from urandom buys you nothing, other than to fool /dev/random into thinking it has more entropy than it actually does. > > On a typical Linux system, /dev/random and /dev/urandom get their entropy from the same source, so feeding pseudorandom numbers from one to the other is essentially lying to the kernel; it will get its revenge on you for that lie, eventually. Indeed, the correct solution is to use /dev/urandom instead of /dev/random. http://www.2uo.de/myths-about-urandom/
