Custom SSL

Prerequisites

First ensure your pod has a custom DNS assigned to it. This guide shows you how:

Choose your SSL Mode

Flexible SSL encrypts the data from Cloudflare to the End User, but does not enforce encryption between your Pod and Cloudflare. This is fine for most cases where information is meant to be public (most informational websites and DApps without user specific info being served)
Strict SSL encrypts the data both from CloudFlare to the End User as well as the data between your Pod and Cloudflare. This is best when you are serving sensitive data such as personal user info (common with Web2 based sites with personal information kept behind a login)
Flexible provides the fastest setup and Strict provides a more complete encryption solution with a few more technical steps.
Both options are completely valid which is why they are both supported. Pick the one that matches your requirements best.
