[Pki-users] Dogtag profile for encryption certificate with storing private key in DRM/KRA

Hi:

The CRMFPopClient generates the key pair on its own, it does not get it from the KRA.
It uses the transport cert to essentially wrap the data for transit.

And that private key gets sent to the kra.

Also that line of code I believe is in some test driver program.
It gets the same transport cert using some rest call.
