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 ...

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 ...

Generated by a cryptographic algorithm, a cryptographic checksum is a mathematical value assigned to a file sent through a network for verifying that the data contained in that file is unchanged. The ...

What are the differences between Message Authentication Codes (MAC) and Keyed-Hashing for Message Authentication (HMAC)? Could you provide an example of an instance where one is a better option than ...

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 ...
