Included mozroots.exe crashing in Unity

I'm trying to set up my game to communicate with a REST API on a web server. The only way so far that I've found to use SSL is through HttpWebRequest/Response. Mono by default doesn't trust any CAs, so I have to run mozroots.exe to import CAs to validate SSL certs. Here is the command line I'm using and the error. Does anyone know a fix for this bug, any way around this, or another way to use HTTPS in Unity.
