Google helps put aging SHA-1 encryption out to pasture
The decades-old SHA-1 encryption used to protect websites is already dying, but a discovery from Google and security researcher CWI Amsterdam could be the killing blow. For the first time, they've found a way to generate a "collision" and create the same critical hash function multiple times. The discovery will make it 100,000 times easier for attackers to slip malicious files into websites or servers than by a brute force attack. That new should help end its use, increasing security around the internet.
