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.

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 ...
