Secret Key Cryptography: Ciphers, from Simple to Unbreakable

Explore the fascinating and rich world of Secret Key cryptography! This book provides practical methods for encrypting messages, an interesting and entertaining historical perspective, and an incredible collection of ciphers and codes--including 30 unbreakable methods.

Secret Key Cryptography teaches anyone how to create a wide range of ciphers--even if you have no background in math or creating codes. You'll combine Secret Key techniques to achieve ciphers that are effectively uncrackable and avoid common pitfalls. The book reveals scores of different cipher methods, including both historic examples and current innovations in the field.

In Secret Key Cryptography, you'll learn how to efficiently encrypt and transmit very large files using fast stream ciphers, and discover alternatives to AES encryption. Simple language, optional mathematical sidebars, and fun-to-solve mini-ciphers help make learning serious cryptographic concepts both easy and engaging.
