====Custom SSL Certificates====

Your ARDI license includes an SSL certificate that is signed by Optrix, the authors of the ARDI system.

This is a //self-signed// certificate to help provide an additional layer of security and allow users to access web technologies (such as video, audio and position capture) that are only available on secure web-pages.

However, this certificate will give your clients warnings unless they [[https://ardi.com.au/certificates/|install the Optrix certificate chain]] on their devices.

You can instead provide your **own** SSL certificate to your ARDI server at any time.

===Files and Formats===

Ensure you have the following files...

  * The root/intermediate certificate chain,
  * The server certificate,
  * The ARDI servers private key

The all files but the private key should be in **.pem** format. 

===Installing Your Certificate(s)===

Simply copy these files into the **/ssl** folder of your ARDI installation.

^File Name^Contains^
|chain.pem|The SSL certificate chain in PEM format|
|server.pem|The servers public key in PEM format|
|server.key|The servers private key|

===Restart the Service===

Once this step is complete, restart the **Apache2** service to use your updated SSL certificates.
