SHA-1 Broken - Schneier on Security
SHA-1 Broken SHA-1 has been broken. Not a reduced-round version. Not a simplified version. The real thing. The research team of Xiaoyun Wang, Yiqun Lisa Yin, and Hongbo Yu (mostly from Shandong University in China) have been quietly circulating a paper describing their results: collisions in the the full SHA-1 in 2**69 hash operations, much less than the brute-force attack of 2**80 operations base
