Cryptology

Cryptology: Classical and Modern, 2nd Edition, is a textbook that introduces the principles of disguising and recovering information alongside its historical and cultural significance. The text examines how ciphers conceal information and how analysts work to break them.

The volume addresses classical cipher systems and modern cryptographic methods, including public-key cryptography and message authentication. It also explores historical applications such as the Enigma machine and explains the core processes of encryption and decryption.

Requiring no background in programming or college-level mathematics, this 2018 edition expanded the original text to support both technical and non-technical students across study levels in a one-semester course.
