Generating Certificate Request

Overview

This page describe the process to generate certificate request.

Note that the PKI Client CLI provides a simplified mechanism to generate and submit a CSR for client certificates. See Certificate Profiles.

Generating PKCS #10 Request

If key archival is not needed, a PKCS #10 request can be generated with the following methods:

• Generating Certificate Request with PKCS10Client

Using certutil

Prepare noise file and password file:

$ openssl rand -out noise.bin 2048
$ echo Secret.123 > password.txt

To generate the request onto the screen:

$ certutil -R \
 -d ~/.dogtag/nssdb \
 -f password.txt \
 -s "uid=testuser,ou=people,dc=example,dc=com" \
 -g 2048 \
 -z noise.bin \
 -o testuser.csr \
 -a


Generating key.  This may take a few moments...

The CSR is stored in testuser.csr.

See also NSS Database.

Using openssl

$ openssl req -newkey rsa:2048 -keyout testuser.key -nodes -new -out testuser.csr -subj "/UID=testuser/OU=people/DC=example/DC=com"
Generating a 2048 bit RSA private key

writing new private key to 'testuser.key'

Generating CRMF Request

If key archival is needed, generate a CRMF request.

Getting KRA Transport Certificate

To export KRA transport certificate from the server side:

$ pki-server cert-export kra_transport --cert-file kra_transport.crt

To export KRA transport certificate from the client side:

$ pki kra-cert-transport-export --output-file kra_transport.crt

Alternatively, first find KRA transport certificate’s serial number by its subject DN:

$ pki ca-cert-find --name "DRM Transport Certificate"
---------------
1 entries found
---------------
  Serial Number: 0x7
  Subject DN: CN=DRM Transport Certificate,O=EXAMPLE
  Status: VALID
  Type: X.509 version 3
  Key Algorithm: PKCS #1 RSA with 2048-bit key
  Not Valid Before: Thu Oct 22 18:26:11 CEST 2015
  Not Valid After: Wed Oct 11 18:26:11 CEST 2017
  Issued On: Thu Oct 22 18:26:11 CEST 2015
  Issued By: caadmin
----------------------------
Number of entries returned 1
----------------------------

Then save the certificate into a file:

$ pki ca-cert-show 0x7 --output kra_transport.crt
-----------------
Certificate "0x7"
-----------------
  Serial Number: 0x7
  Issuer: CN=CA Signing Certificate,O=EXAMPLE
  Subject: CN=DRM Transport Certificate,O=EXAMPLE
  Status: VALID
  Not Before: Thu Oct 22 18:26:11 CEST 2015
  Not After: Wed Oct 11 18:26:11 CEST 2017

Using CRMFPopClient

$ CRMFPopClient \
    -d ~/.dogtag/nssdb \
    -p Secret.123 \
    -a rsa \
    -l 1024 \
    -b kra_transport.crt \
    -n "uid=testuser,o=example"
