Develop a greater intuition for the proper use of cryptography. This book teaches the basics of writing cryptographic algorithms in Python, demystifies cryptographic internals, and demonstrates common ways cryptography is used incorrectly. Cryptography is the lifeblood of the digital world’s security infrastructure. From governments around the world to the average consumer, most communications are protected in some form or another by cryptography. These days, even Google searches are encrypted. Despite its ubiquity, cryptography is easy to misconfigure, misuse, and misunderstand. Developers building cryptographic operations into their applications are not typically experts in the subject, and may not fully grasp the implication of different algorithms, modes, and other parameters. The concepts in this book are largely taught by example, including incorrect uses of cryptography and how "bad" cryptography can be broken. By digging into the guts of cryptography, you can experience what works, what doesn't, and why. What You’ll Learn Understand where cryptography is used, why, and how it gets misused Know what secure hashing is used for and its basic properties Get up to speed on algorithms and modes for block ciphers such as AES, and see how bad configurations break Use message integrity and/or digital signatures to protect messages Utilize modern symmetric ciphers such as AES-GCM and CHACHA Practice the basics of public key cryptography, including ECDSA signatures Discover how RSA encryption can be broken if insecure padding is used Employ TLS connections for secure communications Find out how certificates work and modern improvements such as certificate pinning and certificate transparency (CT) logs Who This Book Is For IT administrators and software developers familiar with Python. Although readers may have some knowledge of cryptography, the book assumes that the reader is starting from scratch.

"Matrix Protocol End-to-End Encryption" Matrix Protocol End-to-End Encryption offers a comprehensive and authoritative exploration of the security foundations underpinning one of the most versatile and decentralized communication protocols in the modern digital landscape. The book opens with an in-depth analysis of Matrix’s federated architecture, examining how its protocol design embraces openness while meeting the formidable challenges of distributed trust, device proliferation, and sophisticated threat models. Drawing on insights from the evolution of secure messaging—including OTR, Signal, and pioneering advances unique to Matrix—the text deftly contextualizes why end-to-end encryption (E2EE) is indispensable for genuine user privacy across federated networks. Delving into the mechanics and theory of Matrix’s E2EE, the book methodically dissects cryptographic primitives, key management strategies, and verification mechanisms essential to robust security. Leading readers through the technical intricacies of the Olm and Megolm protocols, it details how Matrix balances forward secrecy, usability, and scalability in both one-to-one and group communications. From complex session lifecycles and trust chains to nuanced workflows for device verification, compromise detection, and secure key recovery, the narrative addresses both the cryptographic rigor and operational realities that define Matrix’s approach. Beyond protocol specifications, the book investigates the lived experience of deploying and evolving E2EE at scale: implementation best practices, compliance and legal considerations, community governance, and the perennial challenge of usability. It further contemplates advanced topics such as metadata minimization, encrypted media, bridging to external networks, and post-quantum cryptography. Matrix Protocol End-to-End Encryption is an essential resource for architects, engineers, and security professionals dedicated to understanding and shaping the future of secure, interoperable communication platforms.
