CMC Examples Getting Role User Certificate

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

$ CMCRequest 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

• import the new certificate
