“The Rohonc Code is a valuable guide for how to approach an old unsolved cipher. Historians will benefit from learning some of the mathematical approaches that Láng describes, while mathematicians will benefit from Láng’s detailing of how he pursued potential historical leads.”—Craig P. Bauer, author of Unsolved! The History and Mystery of the World’s Greatest Ciphers from Ancient Egypt to Online Secret Societies
