The process of installing a SSL certificate on your IS is very simple. Please follow the process below:

Please click on  More=>Server=>Settings=> and then the tab SSL Certificate Settings - As you see in the screenshot below:

The certificate should be uploaded and the supported format is .pem. It should be uploaded in two parts:

(if it's a .pfx file then it should be converted to .pem file as .pfx is for Windows only)

1. The certificate file

2. The key file

PEM files use ASCII encoding, so you can open them in any text editor such as notepad, MS word etc. Each certificate in the PEM file is contained between the ---- BEGIN CERTIFICATE---- and ----END CERTIFICATE---- statements. The private key is contained between the ---- BEGIN RSA PRIVATE KEY----- and -----END RSA PRIVATE KEY----- statements. The CSR is contained between the -----BEGIN CERTIFICATE REQUEST----- and -----END CERTIFICATE REQUEST----- statements.

Once the files uploaded, you can click on the "change" button to save your change and have your certificate applied.

The next connection to the IS will be a https one.
