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 ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

Hash functions are everywhere in computer science and cryptography. We use them to create fingerprints of data for quick comparison, to check file integrity, to organize data in hash tables, and, ...

Your hardware is ready. Now, let's load up some software and get cracking. In Part I of this series, I explained how password cracking works in general terms and ...
