Plex requires a pkcs12 certificate to be generated, but we’re going to use a python script for that. Openssl rsa -in -out plex.keyĬreate the Certificate openssl x509 -req -days 5475 -in plex.csr -signkey plex.key -out plex.crt Now we’re going to strip the passphrase out of the keyfile, it will prompt you one more time for the passphrase.

openssl req -new -key plex.key -out plex.csr There are plenty of free services that provide dynamic DNS for this if you don’t have the ability to add an A record somewhere. The only important thing that must match is the Common Name which should be valid FQDN / hostname of your home machine where any external clients will connect. You can enter any value you want here, don’t overthink it. Next you’ll create the certificate signing request and be prompted with some questions. Verifying - Enter pass phrase for plex.key: Generating RSA private key, 1024 bit long modulus

This will prompt you for a passphrase, enter something here and remember it. We’re going to do everything else as the plex user inside their home directory. We’re going to be using the openssl commands and a Python script to create our certificates. This is aimed for a CentOS7/RHEL7 installation, substitute appropriately for other Linux distributions.

We will focus on creating, installing and using your own self-signed SSL certificates to encrypt connection streams to the outside world. I am going to assume you have Plex Media Server already setup, if not there are plenty of other guides to do this. Here’s how to use your own self-signed SSL certificates to encrypt connection streams. Plex is a fork of the Open Source Kodi (previously XBMC) project from 2008, the Plex Media Server has evolved into what amounts to a free, personal Netflix + Spotify that lets you stream home content to devices or browsers with an optional subscription model for added features.
