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

If you see the email I sent the other day,
we make use of the CRMFPopClient tool that uses the transport key to wrap the private key.

But after this change it is not adding private key to DRM: /

Marcin, 

Not sure what exactly you're looking for here, but the beauty of profiles is you can create your own. If the ECC profile works as you would expect, you can always create a copy with a new name and change the appropriate lines. A quick diff of the two profiles you mention shows that there's not a lot that's different between the two: 

diff caEncECUserCert.cfg caEncUserCert.cfg 
1c1 
< desc=This certificate profile is for enrolling user ECC encryption certificates. It works only with latest Firefox. 
--- 
> desc=This certificate profile is for enrolling user encryption certificates with option to archive keys.

In theory (I have not tested this) you should be able to change the lines for 'policyset.encryptionCertSet.3.constraint.params.keyType' and 'policyset.encryptionCertSet.3.constraint.params.keyParameters' to match the caEncUserCert.cfg profile and keep everything else the same. If you have the KRA installed and configured to work with your CA, the encryption keys should automatically be archived in the KRA.

there is a caEncECUserCert that works as I expect but generates Eliptic curve certificate. Is there any eqiuvalent for RSA? And next question is: could I use this profile to generate enduser certificate remote by calling REST service?

Hi All, 

What I want is simple profile for requesting encryption(not sign) personal certificate that will private key be stored in KRA/DRM. I check existing profiles and found profile that name and description meet the goals I want to achieve. 

CaEncUserCert.cfg 

this profile was not visible I change that. I opened this profile in end user CA application 


Certificate Profile - Manual User Encryption Certificates Enrollment 

This certificate profile is for enrolling user encryption certificates with option to archive keys. Certificate Request Input 
	* Certificate Request Type list ( pcks10 or crmf) 
	
	* Certificate Request (text area for request) 
Subject Name 
-fields with info about user(propably should be same values that were in certificate request) 
Requestor Information 
- info about requestor 

How it's possible to store private key without even sending it to CA? can be private key enclosed into "Certificate Request"? If answer is no - as I think why there is a "option to archieve keys"?
