Practical Cryptography in Software Development

"Practical Cryptography in Software Development: The How-To Guide" is an essential resource for anyone seeking to understand and apply cryptographic principles in the realm of software engineering. This book demystifies the complex world of cryptography by bridging the gap between theoretical concepts and real-world applications. Tailored for both beginners and experienced practitioners, the text provides a clear, structured journey through the fundamental aspects of cryptography, including symmetric and asymmetric systems, hash functions, and digital signatures, all while emphasizing practical implementation. Delving into contemporary challenges, the book explores the critical role of cryptography within emerging domains like cloud computing and the Internet of Things (IoT). Through comprehensive overviews of secure communication protocols and deployment strategies, readers are equipped with the tools needed to enhance data protection and secure digital interactions. Rich with case studies and practical insights, the guide not only fortifies developers' cryptographic skills but also empowers them to construct secure, reliable software in an increasingly digital world.
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.
Practical Cryptography

Cryptography, the science of encoding and decoding information, allows people to do online banking, online trading, and make online purchases, without worrying that their personal information is being compromised. The dramatic increase of information transmitted electronically has led to an increased reliance on cryptography. This book discusses th
