After nine years of research and competitions, the National Institute of Standards and Technology released the final version of its Secure Hash Algorithm-3 standard Wednesday. SHA-3 is a cryptographic ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

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 am having a hard time understanding exactly how salting passwords works in linux, and was hoping someone can help me understand it better. I understand the general concept of cryptographic salt, but ...

So far in this chapter we have focused on the choice of a single class of algorithms, hashes, as a way to get the most performance out of our security. While hashes are extremely useful for a wide ...

As the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) prepares to announce the winner of its competition to find the next-generation cryptographic hash algorithm, ...

Cardano founder Charles Hoskinson said post-quantum cryptography exists, but would slow blockchains without hardware support.

Hoskinson warned that rushing post-quantum upgrades could seriously slow down blockchain networks and raise costs.
