The Virginia Tech Certification Authority is responsible for issuing and managing digital certificates for Virginia Tech affiliated entities. The VTCA is the core of the Virginia Tech Public Key Infrastructure (PKI). The VTCA guarantees the identity and the authenticity of the entities it issues digital certificates to by using approved policies and procedures outlined in the Virginia Tech Certification Policy document. The diagram below shows the chain of trust, with our TLS Server Certificates having external trust through AddTrust (Comodo) and our Personal Digital Certificates having external trust through GlobalSign. The TLS server certificates are now signed by the InCommon CA. Please click on the appropriate certificate to the right to submit a request through the service catalog.
