The book introduces historical ciphers to build intuition. (e.g., Caesar cipher, monoalphabetic, and polyalphabetic like Vigenère) replace characters with others, while transposition ciphers (e.g., rail fence, columnar) rearrange them. Kahate emphasizes that these classical methods are easily broken by frequency analysis or brute force, setting the stage for modern, mathematically stronger algorithms. | Chapter | Topic | |---------|-------| | 1
