CMC Examples Getting Role User Certificate - dogtagpki/pki GitHub Wiki

Getting Role User (Administrator, Agent, or Auditor) Certificate

A user’s role status is determined by one’s group membership within the certificate authority groups database. This section only demonstrates how a role user’s certificate can be obtained via a CMC request. Once the certificate is obtained successfully, the administrator of the certificate authority should follow documented instruction to add the user and his/her certificate into the proper group membership.

Note: This procedure differs from the User-signed procedure above in that it requires a CA agent to sign the CMC request. Please pay special attention to the servlet parameter value in the HttpClient config file.

Agent-signed CMC requests Example

This example demonstrates a CMC request signed by an existing CA agent. It can often be used for getting a role user certificate.

First, the user that wishes to obtain a certificate performs the following:

  • Generate a cert request (pkcs10 or crmf)

    • Note: the following CRMFPopClient example assumes that kra.transport contains the KRA’s transport certificate in PEM format to achieve key archival.

    • Also note that HSM is assumed to be used by KRA, hence the additional of the option -w "AES/CBC/PKCS5Padding"

$ CRMFPopClient -d . -p netscape -n "cn=admin cfu, uid=admincfu" -q POP_SUCCESS -b kra.transport  -w  "AES/CBC/PKCS5Padding" -v -o crmf.req

Storing CRMF requrest into crmf.req

  • Hand the CSR to a CA agent

Now, a CA agent should perform the following:

  • Take the CSR that the user generated from the above step and store in a file. The CSR should be in BER data format as was directly output by the either of the Dogtag tools (CRMFPopClient and PKCS10Client) depicted above.

  • Edit CMCRequest cfg file so that

    • the nickname contains the CA agent signing cert

    • the format matches the csr format in the above step

    • the input points to the CSR file

    • the output points to where you intend the output to go

    • see cmc config file: cmc.role_crmf.cfg

The CMC enrollment request in data format is stored in /root/cfu/test/cmc/cmc.role_crmf.req

  • submit the CMC request

    • make sure clientmode=true

    • make sure nickname=<the agent certificate that signs the cmc request>

    • make sure the HttpClient config file servlet points to servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCUserCert

    • see HttpClient config file: HttpClient_role_crmf.cfg

$ HttpClient HttpClient_role_crmf.cfg

The response in data format is stored in /root/cfu/test/cmc/cmc.role_crmf.resp

  • Check the result: (note that the response is a PKCS#7 cert chain in the success case)

    • At the end of the CMCResponse call below, observe that

      • the CMCResponse has a SUCCESS status

      • the new certificate was really issued

      • the certificate bears the subject name as intended

      • If key archival is set up, check that key is archived (only available if the underlying request is CRMF)

      • Check relevant audit messages in audit log (e.g.) TBD

  • Hand the resulting certificate to the user

  • add the user certificate to user record and add the user to the appropriate role group member per instruction.

Once the certificate is received, the user would want to import the certificate:

  • import the new certificate
