Saw a page this morning that makes a disconcerting claim:
Treadwell Stanton DuPont today announced its researchers quietly broke the SHA-256 hashing algorithm over a year ago
Conveniently, their “disclosure policy” says they won’t say how they did it, so I guess you either take their word for it or not. Can anyone corroborate or refute this claim? And if it’s true, what would the impact be?
