Purpose of TANRC Root Certificate

Because of the nature of computer security and the ability to control trust, despite the availability and cheap pricing of commercial SSL certificates, TANRC and its programs have decided to continue to use our internal certificate infrastructure for security. This decision was made for several reasons, mostly because TANRC requires higher levels of security with its regulated computer systems than commerical SSL certificate vendors are able to support.

Installing the TANRC Root Certificate will not cause any harm to your computer. The certificate is like a reference book to your computer in order for it to help validate the validity of the purported TANRC managed application you are trying to connect to. As it is like a reference book, it is only used by your computer to look up the validity of a service when you want to connect to our servers. The certificate is just a cryptographic key, nothing more.
