Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

The SHA1 (Secure Hash Algorithm 1) cryptographic hash function is now officially dead and useless, after Google announced today the first ever successful collision attack. SHA1 is a cryptographic hash ...

AI success depends on whether enterprise data is ready, reachable, and close enough to the workloads that need it. In this eSpeaks episode, Dell Technologies’ Vrashank Jain explains why fragmented ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...

The PKI industry recommends that every SHA-1 enabled PKI move to the vastly more secure SHA-2. Here's why and how. For the past two years, I’ve been busy helping Public Key Infrastructure (PKI) ...

I may have missed something, but from a quick review of the relevant RFCs, it looks as if 3des-cbc and hmac-sha1 are still the [only] required encryption and hashing algorithms. This raises two ...
