SHA-1 Encryption Broken
• Schneier on SecurityThere's a new cryptanalysis result against the hash function SHA-1:
Abstract: We present in this article a freestart collision example for SHA-1, i.e., a collision for its internal compression function. This is the first practical break of the full SHA-1, reaching all 80 out of 80 steps, while only 10 days of computation on a 64 GPU cluster were necessary to perform the attack. ...
