 Although this isn’t an exhaustive treatise on cryptography, we do cover a broad spectrum of OpenPGP, PGP, and GnuPG topics.Chapter 1, “Cryptography Kindergarten,” covers the basic ideas behind encryption. I discuss the basic encryption types used by OpenPGP, what separates an encryption system from a code, and when you should use each sort of encryption with GnuPG. Chapter 2, “Understanding OpenPGP,” teaches you the basic ideas underlying OpenPGP. I discuss the Web of Trust, keys and subkeys, keyrings, and keyservers, as well as ideas you must understand before installing either package. I also discuss how to safely handle your key, how to get your key signed or revoked, and how to make your key publicly available. Chapter 3, “Installing PGP,” guides you through installing the PGP desktop client. Chapter 4, “Installing GnuPG,” walks you through installing GnuPG on both Windows and Unix-like systems. Chapter 5, “The Web of Trust,” discusses how OpenPGP keys are connected to one another, identity verification, and keysigning. This is perhaps the most important part of Open-PGP usage, and is what makes the system unique. Real security doesn’t come from software; it comes from people. Unfortunately, people are also the weakest part of any security system. Here I discuss both good and bad ways to handle keysigning. Chapter 6, “PGP Key Management,” takes you through managing the Web of Trust with PGP software. Chapter 7, “Managing GnuPG Keys,” shows you how to manage the Web of Trust with GnuPG. Chapter 8, “OpenPGP and Email,” discusses how to integrate OpenPGP into your email and some of the issues that can arise with email usage and PGP. We cover topics such as clearsigning versus PGP/MIME, retaining copies of encrypted messages, and so on. Chapter 9, “PGP and Email,” discusses how to use PGP software with email. Chapter 10, “GnuPG and Email,” covers integrating GnuPG with various email clients. Chapter 11, “Other OpenPGP Considerations,” shows you how to deal with some of the things that can go wrong with OpenPGP, how to use OpenPGP as part of a group of people, and how to use some other significant features in GnuPG and PGP.
