Another year, another book to update. The third edition of OpenSSL Cookbook, my free book that covers command-line usage of OpenSSL, is now available for your pleasure. Although the structure of the book remains the same, it’s been significantly updated with the help of Matt Caswell, a member of the OpenSSL development team. The largest change, of course, is that the material is now fully up to date with TLS 1.3.
