Serious Cryptography, 2nd Edition

“Like having a wise friend explain all of cryptography’s mysteries without making your head spin. The book stands out for its practical approach, which provides real-world applications and insights. It is considered mandatory reading for security engineers undergoing onboarding within my team, providing an essential foundation for their professional development.” —Anastasiia Voitova, Head of security engineering at Cossack Labs“Fills [the need for an accessible and readable resource on cryptography], taking the reader on a journey through different cryptographic tools and how to use them, as well as the important ‘what can go wrong’ sections that fill the book… Serious Cryptography is an enjoyable introduction to the field, and one that comes highly recommended.” —Yehuda Lindell, Head of Cryptography at Coinbase“A properly serious introduction . . it has the right structure on which one can build a thorough understanding of cryptography.”—Thomas Pornin, Technical Vice President, NCC Group
