Team R2R emulators use this certificate to establish a local, secure HTTPS loopback connection (127.0.0.1) so your software believes it is talking to an official licensing server.
However, this technical convenience carries profound security implications. The root certificate store is the bedrock of system security.

While R2R is a known entity within its niche, installing their root certificate creates a vulnerability. A malicious actor could, in theory, compromise the R2R private key or distribute a fake certificate under the same name. Once the root is installed, the system will trust any code signed by that key—good or bad. Furthermore, unlike commercial root certificates, self-signed roots do not come with revocation mechanisms or oversight. It is a permanent, silent change to the operating system’s trust model.
