"Aumasson includes his own observations and editorial comments in the entries, which makes for a more interesting read than most dictionaries. . . . Readers also can use the dictionary for a crash course in the field and assemble a reading list of important texts." —Veronica Combs, Tech Republic"An opinionated mix of witty definitions, mentions of niche cryptographic constructions and obscure algorithms, historical curiosities, and cryptography nerd jokes . . . As written in its introduction, Crypto Dictionary is meant to be an entertaining read, so that 'any reader can open the book at a random page and discover a yet unknown notion, excavate an obscure concept, or read an anecdote about a familiar term.', and it perfectly fulfils this role." —Julien Voisin, Dustri.org"In terms of usefulness, I think Crypto Dictionary has definitely earned its place on my bookshelf next to Serious Cryptography. I can confidently say that I will be coming back to Crypto Dictionary over time as a starting point for researching 'new-to-me' concepts in cryptography. I would highly recommend this book to anyone with a general interest in cryptography or needing a basic guide to ‘translate’ crypto jargon to English."—Craig Young, Principal Security Researcher, Tripwire
