In today's digital world, where trust and security are paramount, Public Key Infrastructure (PKI) has emerged as an essential technology for safeguarding online interactions and protecting sensitive data. This comprehensive guide delves into the world of PKI, providing readers with a thorough understanding of its concepts, applications, and best practices. Written in a clear and accessible style, this book is designed for IT professionals, students, and anyone seeking to enhance their knowledge of PKI. It begins by introducing the fundamental principles of PKI, explaining how digital certificates, cryptographic algorithms, and trust models work together to create a secure foundation for online communication and transactions. The book then explores the diverse applications of PKI across various industries, including e-commerce, banking, healthcare, and government. Readers will learn how PKI secures online transactions, protects sensitive data, and enables secure remote access, among other critical functions. To ensure a comprehensive understanding, the book also addresses common challenges and pitfalls associated with PKI implementations. These include security vulnerabilities, interoperability issues, performance considerations, and cost implications. By understanding these challenges, readers will be better equipped to design, deploy, and manage PKI systems that are robust, scalable, and resilient. With its in-depth explanations, real-world examples, and practical guidance, this book provides readers with the knowledge and skills they need to leverage PKI effectively and enhance the security of their digital interactions. It is an invaluable resource for anyone seeking to navigate the complex world of PKI and implement secure solutions in the digital age. If you like this book, write a review on google books!
Understanding PKI

Release Date: 2003
PKI (public-key infrastructure) enables the secure exchange of data over otherwise unsecured media, such as the Internet. PKI is the underlying cryptographic security mechanism for digital certificates and certificate directories, which are used to authenticate a message sender. Because PKI is the standard for authenticating commercial electronic transactions,Understanding PKI, Second Edition, provides network and security architects with the tools they need to grasp each phase of the key/certificate life cycle, including generation, publication, deployment, and recovery.

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 FeaturesSecure 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 examplesBook 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 learnUnderstand 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 organizationWho this book is 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.
