Reader Plus HTTPS protocol

 First you need to go into the P3Service.json file located here: C:\ProgramData\activePDF\Settings and set authentication to true. For example:

"environment": {
"logFileDirectory": "",
"tempFileDirectory": "",
"authentication": true
}

Next we need to create an SSL certificate.

1. I created a self-signed certificate(You may want to not use a self-signed certificate for your application). You need to get the thumbnail of the certificate. This is what I got for my certificate 083ab4d2c957cb582471cd771e9fb0ea13bc7eb9.
2. Application ID of P3Restservice  {3f1e5d0b-ac15-4ac0-ba3e-925ab7077dd5}. This never changes. 
3. IP address of the machine where RP is installed. Port is going to be 62626 this is the HTTPS port for RP.

Steps

1. Create a self-signed certificate. I used IIS to create one. There may be other methods to create this.
