> Here are some numbers that give a sense of how large scale this computation was:
Nine quintillion (9,223,372,036,854,775,808) SHA1 computations in total
6,500 years of CPU computation to complete the attack first phase
110 years of GPU computation to complete the second phase
So no need to panic or urgently switch, but time to slowly transition
- amalcon 10y agoIt's been time to slowly transition for the better part of a decade. Still, if you need to start now, it's better late than never.

- simias 10y agoArs technica's article is not as optimistic: > Had the researchers performed their attack on Amazon's Web Services platform, it would have cost $560,000 at normal pricing. Had the researchers been patient and waited to run their attack during off-peak hours, the same collision would have cost $110,000. That's within the $75,000 to $120,000 range CWI's Stevens projected in late 2015. Not cheap but definitely achievable by a wealthy individual or corporation.
