56-bit DES is crackable but only is you have the compute power to brute force a 2^56 binary number. Pull out your calculators on that: 72,057,594,037,927,936 permutations
Don't know and hackers or hacktivists (e.g Anonymous) who have that.
Seven Dwarfs could but I would guess it would take weeks??
(guess - no way to measure their compute power)
