CMC Examples User Signed CMC Request without POP - dogtagpki/pki GitHub Wiki

User-Signed CMC Request without POP (Encrypted POP / Decrypted POP)

This example demonstrates a user-signed CMC request where the CRMF request contains no POP, which would subsequently trigger an EncryptedPOP response from the CA and how to prepare the client to respond with DecryptedPOP to complete the certificate issuance. This method will require round trip.

Note that a request that contains no POP is a general indication that it’s not a signing key, so it could not be self-signed.

  • Generate a certificate request with no POP

    • Note that to see Encrypted POP and Decrypted POP in action, the initial CRMF request has to contain no signing pop, hence the POP_NONE directive in the CRMFPopClient command

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

$ CRMFPopClient -d . -p netscape -n "cn=Lady Christina Fu, uid=cfu" -q POP_NONE -b kra.transport -v -o crmf2.req

  • Edit the CMCRequest cfg file to make sure that

    • the nickname contains the user signing cert instead of admin cert

    • make sure identityProofV2.enable=false

    • make sure popLinkWitnessV2.enable=false

    • make sure request.privKey contains the matching private key ID from the CSR generation above

    • see CMC config file: cmc-crmf-EncryptedPOP.cfg

  • Generate CMC Request

  • 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

      • NO CERT was being issued

      • The return controls contains “encrypted POP”

      • The return status is FAIL with failInfo=POP required

      • The request id is displayed under CMC ResponseInfo

      • Check relevant audit messages in audit log (e.g.) Observe that the PROFILE_CERT_REQUEST event is logged and CMCResposne below shows pending state
