In this chapter, we will look at specific implementation details of the most common cryptographic algorithms. It starts with the fundamental XOR function and then discusses the more complex symmetric and asymmetric algorithms in use today.

The chapter concludes with a review of how an asymmetric key algorithm can be used to exchange a shared private key. This enables the use of faster symmetric key algorithms to exchange bulk-encrypted data without developing elaborate key exchange systems.
