Getting Subsystem Certificate

  • Generate a PKCS10 request

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

$ PKCS10Client -d . -p netscape -n "CN=Subsystem Certificate,OU=pki-tomcat,O=mySecurityDomain" -o sys_subsystem_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: 2b49b42471ea7d42153bdb06344a8786cedd3169

-----BEGIN CERTIFICATE REQUEST-----

<snip>
-----END CERTIFICATE REQUEST-----
PKCS10Client: done. Request written to file: sys_subsystem_pkcs10.req

  • Edit the CMCRequest cfg file to make sure that

  • Generate the CMC request

$ CMCRequest cmc.sys_subsystem_pkcs10.cfg

The CMC enrollment request in data format is stored in /root/cfu/test/cmc/cmc.sys_subsystem_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/profileSubmitCMCFullSubsystemCert

    • example: HttpClient_sys_subsystem.cfg

$ HttpClient HttpClient_sys_subsystem.cfg

Total number of bytes read = 3294
after SSLSocket created, thread token is Internal Key Storage Token

The response in data format is stored in /root/cfu/test/cmc/cmc.sys_subsystem_pkcs10.resp

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