Getting OCSP Signing Certificate

  • Generate a PKCS10 Request

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

$ PKCS10Client -d . -p netscape -n "CN=OCSP Signing Certificate,OU=pki-tomcat,O=mySecurityDomain" -o sys_ocsp_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.

  • 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_ocsp_pkcs10.cfg

  • Generate the CMC request

$ CMCRequest cmc.sys_ocsp_pkcs10.cfg
