Message:
use /dev/urandom instead of /dev/random From urandom(4) on OpenBSD For portability reasons, never use /dev/random. On OpenBSD, it is an alias for /dev/urandom, but on many other systems misbehaves by blocking because their random number generators lack a robust boot-time initialization sequence.
