User-Signed EC CMC Request

This example shows generation of an EC cert request that is signed with an a previously issued user EC cert. In this example, we are using the EC cert issued in the above example to sign the next request.

  • Prepare the user signing cert:

    • Copy and paste the previously enrolled EC user cert into a file in PEM format and add to the working NSS database, e.g.:

$ certutil -d . -A -t "u,u,u" -n "cfuEC cert1" -a -i cfu-ec-cert.b64

  • Make sure the EC user signing cert has its key in the NSS database (must show u,u,u):

$ certutil -d . -L

Certificate Nickname                                         Trust Attributes
                                                             SSL,S/MIME,JAR/XPI

cfuEC cert1                                                  u,u,u

  • Generate an EC pkcs10 request, e.g.:

$ PKCS10Client -d . -p netscape -a ec -c nistp256 -o p10-ec2.req -n "CN=cfuEC2"
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: 5db268462ffb0c0c5735a157b5c95d2a760d8c41

  • Create a CMCRequest cfg file, e.g. cmc-p10-user-signed-ec2.cfg

    • make sure nickname contains the EC user cert that was issued previously

    • make sure the input is the CSR we just generated from the PKCS10Client command above

  • run CMCRequest to generate a user-signed CMC request:

$ CMCRequest cmc-p10-user-signed-ec2.cfg

The CMC enrollment request in binary format is stored in /root/cfu/test/cmc/cmc.p10-ec2.req

  • Create the HttpClient cfg file (e.g. HttpClient.p10-ec2.cfg)

    • Make sure nickname contains the same EC user signing cert that was used to sign the CMC request from CMCRequest above

  • Run HttpClient to submit the CMC request

$ HttpClient HttpClient.p10-ec2.cfg
