openbsd actually has /dev/arandom as a cryptographically secure psuedo random number generator. it's done in kernel using the ARC4 algorithm (equivilent to the RC4 stream cipher and PRNG). it's not /dev/crandom.

$ uname -a
OpenBSD jose.someplace.com 3.4 GENERIC#57 i386
$ ls -l /dev/*random
crw-r--r-- 1 root wheel 45, 4 Nov 11 04:50 /dev/arandom
crw-r--r-- 1 root wheel 45, 3 Oct 30 14:05 /dev/prandom
crw-r--r-- 1 root wheel 45, 0 Oct 30 14:05 /dev/random
crw-r--r-- 1 root wheel 45, 1 Oct 30 14:05 /dev/srandom
crw-r--r-- 1 root wheel 45, 2 Nov 11 04:50 /dev/urandom
