@mo @cccpresser @q strictly speaking, 4 is exactly as random as any n such that n is a member of the set of natural numbers.
But it's not exactly as likely to be tested by an adversary as any other..
@simon_brooke it's random but it's easy to guess.
Realistically you want a certain size requirement here, just like you don't pick small primes with RSA, no matter how random they are.

OMG is this literally a realisation of this old joke in real life?
int random() {
// guaranteed random: obtained by dice roll
return 4;
}
