TAGLINE

Gain practical OpenSSL skills for real-world cybersecurity challenges

KEY FEATURES

● Master OpenSSL’s command-line tools and C APIs to build secure and practical cryptographic applications

● Gain a complete understanding of cryptography from foundational theory to advanced hardware integration with OpenSSL Engines

● Apply your OpenSSL knowledge to real-world use cases including IoT security PKI setup and secure communications

DESCRIPTION

OpenSSL is the backbone of secure communication on the internet, trusted by developers, enterprises, and governments alike. Practical Network Security with OpenSSL equips you with the knowledge, real-world context, and hands-on skills to master OpenSSL—from its command-line tools to its C library APIs—for implementing robust, enterprise-grade cryptographic solutions.

You’ll begin with a solid foundation in cryptographic principles and the role of OpenSSL in modern security systems. The book then guides you through practical usage, covering symmetric and asymmetric encryption, Public Key Infrastructure (PKI), and secure communications. Real-world examples and C code snippets help you confidently apply OpenSSL in standalone applications, enterprise-grade solutions, and hardware-based security environments such as HSMs and TPMs.

By the end of this book, you’ll have the expertise to confidently use OpenSSL for designing, implementing, and managing cryptographic solutions across various domains. Whether you're securing financial transactions, IoT networks, or enterprise authentication systems, you’ll be equipped with the tools and knowledge to build secure, future-ready applications. Don’t get left behind—secure your systems like the pros do with OpenSSL mastery.
