RIT Certificate Authority Content

RIT Certificate Authority

The RIT Certificate Authority, created and maintained by ITS, provides a chain of trust for electronic communications. It forms the basis of a public key infrastructure for services (particularly those protected with SSL/TLS encryption) of value to the campus.

We recommend that all RIT-owned computers import and trust the RIT Certificate Authority.

In nearly all cases, your System Administrators have taken care of this for you, and the below certificates should not be necessary. Importing the certificate for the RIT Certificate Authority (CA) allows your computer to accurately identify other certificates that are chained from it. Trusting the imported CA certificate avoids presenting dialogs to you when it encounters a service that has been signed by it.

Manually import and trust the RIT Certificate Authority

If necessary, you can easily manually import the RIT CA files below. Operating systems and Web browsers typically provide a way to do this, which can vary. Please contact ITS ResNet for assistance with manually importing these certificates, if necessary.

Importing the certificates and trusting the RIT CA manually is one way to set up the RIT CA in certain third-party applications, such as Mozilla Firefox, that do not use the operating system certificate store.

These certificates are only good for several years at a time, and must be re-imported and trusted as new ones are posted.
