CMC support in Certificate Manager



CM SDK is a Java API for certificate management. It provides the same functionality as the CM clients RA and CC except for support of PKCS #10 requests.

The CM SDK is powerful and easy to use and can be operated using both real and virtual Registration Officers.

Device authorization 

To control which devices can request certificates, authorization is required. Different enrollment protocols require different authorization. 

Certificate Manager allows different authorization rules for different protocols, by configuration of protocol handlers. The access to a protocol handler can be restricted to administrators that are CM Officers with the configured roles. The authorization condition can be specified as default for a protocol or per protocol handler.

For more information, see each protocol description.   

Device preregistration

The security of automated enrollment is enhanced with a preregistration feature: any authorized devices must be registered in the Certificate Manager database before they can receive certificates. All registration requests must be signed and can later be audited. This layer of security ensures strong control of all device identities. 

Devices must be preregistered before enrolling with SCEP or CMP. Preregistration can also be set up for other protocols, but it is not required. 

For more information, see Device preregistration for automated enrollment.
