I'm not sure that os.urandom() is correct on OpenBSD. I'm not sure that using getentropy() is correct. getentropy() seems to be high quality but I understand that there is a low quantity of entropy and it can block. I don't know if arc4random() is better: it's no more RC4 on recent OpenBSD, and it has an efficient implementation.
