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

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 from Repository).


This page on Mono Security states that I can use certmgr.exe to add certificates to the mono trust store - FAQ: Security | Mono.

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.


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 posted this question to the Unity Forums:

I used mozroots to import the root certs, here’s how i invoked it:

mono mozroots.exe --import --sync

and that’s the output of the command:

mono mozroots.exe --import --sync

Please note that you can also run this on your player by calling something like this:

System.Diagnostics.Process.Start("mozroots","--import"); I haven’t tested that though…

Also i found mozroots.exe on OS X in this directory:


hope that helps !
