OpenSSL features and commands, by Ivan Ristić
- Provides OpenSSL documentation that covers installation, configuration,
and key and certificate management - Includes instructions and templates for how to build a private CA
- The second chapter focuses on TLS server configuration testing
- Written by the author of SSL Labs and the SSL/TLS configuration assessment tool
- Available in a variety of digital formats (PDF, EPUB); no DRM
OpenSSL Cookbook
is a free ebook built around two OpenSSL chapters from Bulletproof SSL and TLS,
a larger work that teaches how to deploy secure servers and web applications.
