Useful X.509 Certificates: Federal and Other

Validation of HSPD-12/PIV Authentication, Signature and Encryption Certificates

Below are the Federal Common Policy root certificate and the intermediate Entrust Managed Services certificates needed to trust HSPD-12/PIV smart card certificates. Normally Windows and MacOS computers come with Federal Common Policy installed. Further Windows computers will automatically download the required intermediate Entrust Managed Services certificates if needed.

These certificates are provided here to assist administrators and users whose operating systems may not have them already installed. Administrators and users can download these certificates and install them in their local computers if needed.
