If you’re hanging on to the theory that collision attacks against SHA-1 and MD5 aren’t yet practical, two researchers from INRIA, the French Institute for Research in Computer Science and Automation, have demonstrated new attacks that raise the urgency to move away from these broken cryptographic algorithms. Karthikeyan Bhargavan and Gaetan Leurent recently published an...

Google has announced its timeline for deprecating SHA-1 certificates, despite concerns expressed recently that sunsetting the broken encryption hashing algorithm will disconnect millions from the Internet. SHA-1’s demise has been accelerated in recent months since researchers published a paper explaining that practical collision attacks could be months, instead of years, away. Google, on Friday, announced...
