CMC Examples Getting Subordinate CA Certificate

Getting Subordinate CA Certificate

• Generate a PKCS10 request

  • Note: make sure the subject name is as intended.

$ PKCS10Client -d . -p netscape -n "CN=subCA Signing Certificate,OU=pki-tomcat,O=mySecurityDomain" -o ca_pkcs10.req
PKCS10Client: Debug: got token.
PKCS10Client: Debug: thread token set.
PKCS10Client: token Internal Key Storage Token logged in...
PKCS10Client: key pair generated.
PKCS10Client: CertificationRequest created.
PKCS10Client: b64encode completes.
Keypair private key id: 192bda1e7f8f2105e070df51d4fc928b6b3a15e9

• Edit the CMCRequest cfg file to make sure that

  • the nickname contains the agent cert that will sign the request

  • see CMCRequest cfg file example: CMC.sys_subca_pkcs10.cfg

• Generate the CMC request

$ CMCRequest cmc.sys_subca_pkcs10.cfg

The CMC enrollment request in data format is stored in /root/cfu/test/cmc/cmc.sys_subca_pkcs10.req.

• Submit the CMC request

  • make sure the nickname contains the signing agent’s certificate nickname

  • make sure secure=true and clientmode=true

  • make sure servlet=/ca/ee/ca/profileSubmitCMCFullCACert

  • example: HttpClient_sys_ca.cfg

$ HttpClient HttpClient_sys_ca.cfg

The response in data format is stored in /root/cfu/test/cmc/cmc.sys_subca_pkcs10.resp

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