Practical Cryptography in Python
Apress (Verlag)
978-1-4842-4899-7 (ISBN)
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.
Dr. Seth James Nielson is the founder and chief scientist of Crimson Vista, Inc., a boutique computer security research and consulting company. He is also an adjunct professor at Johns Hopkins University where he teaches network security and has also served as the director of advanced research projects at the Information Security Institute. As part of his Hopkins work, he co-founded the cryptodoneright.org knowledge base, through a generous grant from Cisco. Christopher K. Monson has a PhD in machine learning, and has spent over a decade at Google in various engineering, machine learning, and leadership roles. He has broad experience writing and teaching programming courses in multiple languages, and has worked in document password recovery, malware detection, and large-scale secure computing. He is currently serving as the chief technology officer at Data Machines Corp. and teaches cloud computing security as a lecturer at the Johns Hopkins University Information Security Institute.
