SHA-1 Collision Found

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2017/02/sha-1_collision.html

The first collision in the SHA-1 hash function has been found.

This is not a surprise. We’ve all expected this for over a decade, watching computing power increase. This is why NIST standardized SHA-3 in 2012.

EDITED TO ADD (2/24): Website for the collision. (Yes, this brute-force example has its own website.)
