How can I add a certificate to the Mono Trust store?

Unity Engine
1

What I want to do:

I am trying to add a certificate to Unity to enable SSL connection. I preferably only want to approve one root certificate (GoDaddy G2 root certificate downloaded fromhttps://certs.godaddy.com/repository).

Background

This page on Mono Security states that I can use certmgr.exe to add certificates to the mono trust store - http://www.mono-project.com/docs/faq/security/.

There seems to be no certmgr.exe within the mono/2.0 folder packaged with Unity (Unity\Editor\Data\Mono\lib\mono\2.0). Even though the .exe has been in mono since 1.1. The .exe does exist within the MonoBleedingEdge/4.5 folder however I believe there are different Trust stores for each folder so I believe I cannot use this.

Question

Am I able to use another tool / method to add the root certificate to the trust store? Or am I missing the location of the certmgr.exe in the 2.0 mono package?

Additional Notes

In case it makes a difference, I am trying to connect to a Learning Record Store through the Tincan API (new version of SCORM).

I have also asked this question over at Unity Answers: How can I add a certificate to the Mono Trust store? - Questions & Answers - Unity Discussions

I would also like to know how to do this, I don’t really fancy implementing my own certificate validation in Unity

Hi Tristan, have you found any useful information about this issue? Or have you used a workaround for now?

Strange that no one answered you, you can do that by using mozroots.exe, simply run:
mono mozroots.exe --import --sync
and it’ll download and import all the root certs to the mono trust store, here’s what i got when i ran mine:

mono mozroots.exe --import --sync
Mozilla Roots Importer - version 3.4.0.0
Download and import trusted root certificates from Mozilla's MXR.
