Tonight I had the pleasure to present "SSL/TLS for the Pragmatic" to the fine folks of Bucks County Devops. It was a fun evening, and I want to thank the organizers, Mike Smalley & Ben Krein, for the invitation.

It was a great opportunity to summarize 18 months of work at Mozilla on building the Server Side TLS Guidelines. By the feedback I received tonight, and on several other occasions, I think we've achieved the goal of building a document that is useful to operations people, and made TLS just a little easier to understand.

We are not, however, anywhere done with the process of teaching TLS to the Internet. Stats speak for themselves, with 70% of sites still supporting SSLv3, 86% enabling RC4, and about 32% still not preferring PFS over RSA handshakes. But things are getting better every day, and ongoing efforts may bring safe defaults in Linux servers as soon as Fedora 21. We live in exciting times!

The slides from my talk are below, and on github as well. I hope you enjoy them. Feel free to share your comments at julien[at]
