TLS Mastery

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!

(Contains ebook in PDF, epub, and mobi. Both the Beastie Edition and the Tux Edition)
