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 ...

Cryptographic hash functions are a key building block in embedded security. They take input data of any size and convert it into a fixed-length value, called a hash or message digest. This hash acts ...

Hash functions are cryptography’s most widely used primitives, in that they are a fundamental building block used for a wide variety of constructions. The recent attacks of Joux, Wang, and others ...

The cryptography is decades old and well understood, the verification is something a curious player can run by hand, and the ...

BLAKE3 is the most recent evolution of the BLAKE cryptographic hash function. Created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and Zooko Wilcox-O'Hearn, BLAKE3 combines general purpose ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

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 ...

You might not have realized it, but the next great battle of cryptography began this month. It's not a political battle over export laws or key escrow or NSA eavesdropping, but an academic battle over ...

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...
