Use OpenSSL to add security features to your application, including cryptographically strong symmetric and asymmetric encryption, digital signatures, SSL/TLS connectivity, and PKI handling
Key Features: Secure your applications against common network security threats using OpenSSLGet to grips with the latest version of OpenSSL, its new features, and advantagesLearn about PKI, cryptography, certificate authorities, and more using real-world examples
Book 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.
What You Will Learn: Understand how to use symmetric cryptographyGet to grips with message digests, MAC, and HMACDiscover asymmetric cryptography and digital signaturesFocus on how to apply and use X.509 certificatesDive into TLS and its proper usageManage advanced and special usages of TLSFind out how to run a mini certificate authority for your organization
