Cryptanalysis Encryption Series: Breaking a Substitution Cypher We automate the cryptanalysis of a substitution cipher using Rust. With letter frequency data and a dictionary, the script makes educated guesses, applies substitutions, and iteratively refines them to recover plaintext.
Classical Cryptography Encryption Series: The Monoalphabetic Substitution Cipher An introduction to the monoalphabetic substitution cipher, its historical roots, keyspace complexity, and a full implementation in Rust. We demonstrate how it improves on Caesar’s cipher, and where it still falls short.
Encryption Encryption Series: A Civilised Introduction to the Caesar Cipher Discover the historical Caesar cipher, understand its elegant mathematics, and follow a concise implementation in Rust. Learn the cipher’s inherent vulnerabilities through an engaging demonstration of brute-force cryptanalysis.
