Description

Security and networking are essential features of software today. The modern internet is full of worms, Trojan horses, men-in-the-middle, and other threats. This is why maintaining security is more important than ever. OpenSSL is one of the most widely used and essential open source projects on the internet for this purpose. If you are a software developer, system administrator, network security engineer, or DevOps specialist, you’ve probably stumbled upon this toolset in the past – but how do you make the most out of it? With the help of this book, you will learn the most important features of OpenSSL, and gain insight into its full potential. This book contains step-by-step explanations of essential cryptography and network security concepts, as well as practical examples illustrating the usage of those concepts. You’ll start by learning the basics, such as how to perform symmetric encryption and calculate message digests. Next, you will discover more about cryptography: MAC and HMAC, public and private keys, and digital signatures. As you progress, you will explore best practices for using X.509 certificates, public key infrastructure, and TLS connections. By the end of this book, you’ll be able to use the most popular features of OpenSSL, allowing you to implement cryptography and TLS in your applications and network infrastructure.

Who is this book for?

This book is for software developers, system administrators, DevOps specialists, network security engineers, and analysts, or anyone who wants to keep their applications and infrastructure secure. Software developers will learn how to use the OpenSSL library to empower their software with cryptography and TLS. DevOps professionals and sysadmins will learn how to work with cryptographic keys and certificates on the command line, and how to set up a mini-CA for their organization. A basic understanding of security and networking is required.

This is the second book for the subject I know. The previous one is from 2002. This is the book you need to dive into the matter. It will not save you from reading RFCs, ASN.1 and open SSL documentation. But it will make it more easier to understand. The approach of the author is brilliant. It is unbelievable how this matter is presented without single math formula. It looks like very much to tutorial book but it is not. Even book with on such basic level fill some caps in my knowledge. If I had it 8 months ago it would save a lot of pain.In the book you will find answers of many questions like what is x.509 certificate, what is PKI, what is CRL, what is OCSP, how exactly certificate is verified what is common name and how is used. What is subject alternative name and how is used. The book is multipurpose. As I said it is a must for anyone who is going to implement TLS Client/Server communication on its own application which are not WEB based.I am expecting the next book from the author about win32 Crypto API.

Really good for developers that don't care as much about how cryptography works but rather how to deploy cryptography the right way.

This is an excellent book with focus on application part of openssl. The best part is that the book clearly describes not only openssl command line tool but also how the same goals can be achieved through openssl programming. Must read for any one who wants to use openssl as a tool or learn how to use openssl libs in his or her application. Very happy with the purchase !!

Most up to date coverage of OpenSSL 3.0. I'm learning things about Cryptography, particularly TSL and hashing, that was not covered in college classes or found on tutorial websites. A must have book for securing software applications, networks, and websites.Update:Packt books needs to improve their manufacturing processes. The binding on my book is already broken. I took a star off for this. I expect a book that cost $40 to hold together better than this.
