The nth power-moments Sn of classical Kloosterman sums (mod p) are known explicitly only for n ≤ 6. In 2002, we conjectured formulas for Sn (mod 4) for each n > 1, valid for all primes p > n. Here we prove these formulas, and give conjectural congruences for Sn modulo some higher powers of 2 for a few small values of n. For example, we conjecture that if p ≡ 17 (mod 120), so that p = 3s2 + 5t2, then
