Practical RSA Cryptography
"Practical RSA Cryptography" "Practical RSA Cryptography" is a comprehensive and authoritative guide that expertly bridges theory and application in one of modern cryptography’s most enduring systems. The book rigorously explores the mathematical foundations behind the RSA algorithm, including in-depth analyses of prime number theory, modular arithmetic, and the critical assumptions that underpin cryptographic security. Readers are introduced to advanced topics such as the multiplicative group modulo n, the Carmichael function, and algorithmic intricacies of integer factorization—offering both foundational knowledge and insight into what makes RSA resilient against attack. Moving beyond theory, the book delves into real-world cryptographic engineering, offering detailed coverage of core principles, variant algorithms, and essential strategies for robust key management. With chapters on secure random number generation, automated key lifecycle practices in distributed environments, and nuanced treatments of cryptographic library selection, readers gain actionable guidance for implementing RSA across diverse platforms. The book also surfaces common engineering pitfalls, outcome-driven case studies of RSA failures, and best practices for deployment in resource-constrained and high-performance environments alike. Completing its scope, "Practical RSA Cryptography" addresses contemporary threat landscapes, including side-channel and protocol-level attacks, and looks ahead to the unsettling implications of quantum computing on RSA's long-term security. Coverage includes actionable migration strategies, hybrid post-quantum approaches, and the latest industry standards for cryptographic governance, compliance, and risk management. Whether designing secure protocols, safeguarding key assets, or navigating regulatory requirements, this book provides researchers, engineers, and security professionals with the definitive resource for mastering RSA cryptography in practice and in anticipation of what lies ahead.
Practical Cryptography in Python
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.
