TLS Mastery, Tux Edition

Transport Layer Security, or TLS, makes ecommerce and online banking possible. It protects your passwords and your privacy. Let’s Encrypt transformed TLS from an expensive tool to a free one. TLS understanding and debugging is an essential sysadmin skill you must have.

TLS Mastery takes you through:

• How TLS works
• What TLS provides, and what it doesn’t
• Wrapping unencrypted connections inside TLS
• Assessing TLS configurations
• The Automated Certificate Management Environment (ACME) protocol
• Using Let’s Encrypt to automatically maintain TLS certificates
• Online Certificate Status Protocol
• Certificate Revocation
• CAA, HSTS, and Certificate Transparency
• Why you shouldn’t run your own CA, and how to do it anyway
• and more!

Stop wandering blindly around TLS. Master the protocol with TLS Mastery!
