Book Description

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.
