In Secret Key Cryptography: Ciphers, from simple to unbreakable you will

Measure the strength of your ciphers and learn how to guarantee their security
Construct and incorporate data-compression codes
Generate true random numbers in bulk
Construct huge primes and safe primes
Add an undetectable backdoor to a cipher
Defeat hypothetical ultracomputers that could be developed decades from now
Construct 30 unbreakable ciphers

Secret Key Cryptography gives you a toolbox of cryptographic techniques and Secret Key methods. The book’s simple, non-technical language is easy to understand and accessible for any reader, even without the advanced mathematics normally required for cryptography. You’ll learn how to create and solve ciphers, as well as how to measure their strength. As you go, you’ll explore both historic ciphers and groundbreaking new approaches—including a never-before-seen way to implement the uncrackable One-Time Pad algorithm.

Whoever you are, this book is for you! History buffs will love seeing the evolution of sophisticated cryptographic methods, hobbyists will get a gentle introduction to cryptography, and engineers and computer scientists will learn the principles of constructing secure ciphers. Even professional cryptographers will find a range of new methods and concepts never published before.
