Hashing and Encryption, do you know what these are? Some might have heard the names before and believe they are the same. But that is not the case at all. You see, much of the data that is moving ...

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 ...

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 ...

Mining secures blockchain by solving puzzles; hashing ensures data integrity. Large mining pools could have centralized network control, conflicting with Bitcoin’s decentralized ethos. Innovations ...

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 ...

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 ...

Cryptography might seem like a concept from a spy novel or a WW2 documentary, but it’s intrinsic to our digital society. It’s an essential piece of our everyday digital interactions and, most ...

What is Bitcoin’s hash rate? The amount of processing and computing power being given to the network through mining is referred to as Bitcoin’s hash rate. A fixed-length alphanumeric code representing ...
