Note that it follows that 0 < x + 1 < N. Instead, SetBytes // checks that k < N, and we explicitly check 0 != k. Since k can't be // negative, this is strictly equivalent. None of this matters anyway // because the chance of selecting zero is cryptographically negligible. if k, err := bigmod.NewNat().SetBytes(b, c.N); err...
