Crypto can be cryptic. Serious Cryptography, 2nd Edition arms you with the tools you need to pave the way to understanding modern crypto.This thoroughly revised and updated edition of the bestselling introduction to modern cryptography breaks down fundamental mathematical concepts without shying away from meaty discussions of how they work. In this practical guide, you’ll gain immeasurable insight into topics like authenticated encryption, secure randomness, hash functions, block ciphers, and public-key techniques such as RSA and elliptic curve cryptography.You’ll find coverage of topics like:The basics of computational security, attacker models, and forward secrecyThe strengths and limitations of the TLS protocol behind HTTPS secure websitesQuantum computation and post-quantum cryptographyHow algorithms like AES, ECDSA, Ed25519, Salsa20, and SHA-3 workAdvanced techniques like multisignatures, threshold signing, and zero-knowledge proofsEach chapter includes a discussion of common implementation mistakes using real-world examples and details what could go wrong and how to avoid these pitfalls. And, true to form, you’ll get just enough math to show you how the algorithms work so that you can understand what makes a particular solution effective—and how they break. NEW TO THIS EDITION: This second edition has been thoroughly updated to reflect the latest developments in cryptography. You’ll also find a completely new chapter covering the cryptographic protocols in cryptocurrency and blockchain systems.Whether you’re a seasoned practitioner or a beginner looking to dive into the field, Serious Cryptography will demystify this often intimidating topic. You’ll grow to understand modern encryption and its applications so that you can make better decisions about what to implement, when, and how.

Crypto Dictionary is your full reference resource for all things cryptography.Cryptography from A5/0 to ZRTP Expand your mind—and your crypto knowledge—with the ultimate desktop dictionary for all things cryptography. Written by a globally recognized cryptographer for fellow experts and novices to the field alike, Crypto Dictionary is rigorous in its definitions, yet easy to read and laced with humor. You’ll find: A survey of crypto algorithms both widespread and niche, from RSA and DES to the USSR’s GOST cipherTrivia from the history of cryptography, such as the MINERVA backdoor in Crypto AG’s encryption algorithms, which may have let the US read the secret communications of foreign governmentsAn explanation of why the reference to the Blowfish cipher in the TV show 24 makes absolutely no senseDiscussions of numerous cryptographic attacks, like the slide attack and biclique attack (and the meaning of a crypto “attack”)Types of cryptographic proofs, such as zero-knowledge proofs of spacetimeA polemic against referring to cryptocurrency as “crypto”A look toward the future of cryptography, with discussions of the threat of quantum computing poses to our current cryptosystems and a nod to post-quantum algorithms, such as lattice-based cryptographic schemes Or, flip to any random page and learn something new, interesting, and mind-boggling for fun. Organized alphabetically, with hundreds of incisive entries and illustrations at your fingertips, Crypto Dictionary is the crypto world go-to guide that you’ll always want within reach.

It describes how BLAKE was designed and why BLAKE2 was developed, and it offers guidelines on implementing and using BLAKE, with a focus on software implementation.In the first two chapters, the authors offer a short introduction to cryptographic hashing, the SHA3 competition and BLAKE.
