PKI 10.5 Installing OCSP with External Certificates

Endi S. Dewata edited this page Mar 27, 2024 · 5 revisions

Overview

This page describes the process to install OCSP with external certificates in PKI 10.5. In this scenario, the OCSP uses an external CA to issue the OCSP system certificates. The OCSP will join the CA’s security domain.

The installation process consists multiple steps:

  • Initializing installation

    • Creating initial configuration files

    • Creating empty NSS database

    • Generating keys and CSRs (optional)

  • Generating certificates

    • Generating keys and CSRs (optional)

    • Obtaining certificates from external CA

  • Finalizing installation

Preparing for Installation

Prepare a deployment configuration file for step 1 (e.g. ocsp-step1.cfg):

[OCSP]
[email protected]
pki_admin_name=ocspadmin
pki_admin_nickname=ocspadmin
pki_admin_password=Secret.123
pki_admin_uid=ocspadmin

pki_client_database_password=Secret.123
pki_client_database_purge=False
pki_client_pkcs12_password=Secret.123

pki_ds_base_dn=dc=ocsp,dc=example,dc=com
pki_ds_database=ocsp
pki_ds_password=Secret.123

pki_security_domain_name=EXAMPLE
pki_security_domain_user=caadmin
pki_security_domain_password=Secret.123

pki_token_password=Secret.123

pki_external=True
pki_external_step_two=False

pki_ocsp_signing_nickname=ocsp_signing
pki_subsystem_nickname=subsystem
pki_sslserver_nickname=sslserver
pki_audit_signing_nickname=ocsp_audit_signing

Optionally, specify the paths to store the CSR files:

pki_ocsp_signing_csr_path=ocsp_signing.csr
pki_subsystem_csr_path=subsystem.csr
pki_sslserver_csr_path=sslserver.csr
pki_audit_signing_csr_path=ocsp_audit_signing.csr
pki_admin_csr_path=ocsp_admin.csr

If it’s not specified pkispawn will not generate the key and the CSR so they can be generated with a different mechanism.

Optionally, specify the HSM parameters:

pki_hsm_enable=True
pki_hsm_libfile=/opt/nfast/toolkits/pkcs11/libcknfast.so
pki_hsm_modulename=nfast

Then execute the following command:

$ pkispawn -f ocsp-step1.cfg -s OCSP

It will create an NSS database in /var/lib/pki/pki-tomcat/conf/alias and generate CSRs in the specified paths.

Generating Certificates

Use an external CA to issue the certificates:

Place the issued certificates in the location indicated in the next section.

Completing Installation

Prepare a deployment configuration for step 2 (e.g. ocsp-step2.cfg) by copying it from step 1 (i.e. ocsp-step1.cfg) and make the following changes.

Specify step 2 with the following parameter:

pki_external_step_two=True

If pkispawn did not generate the CSRs, specify the paths in the following parameters:

pki_ocsp_signing_csr_path=ocsp_signing.csr
pki_subsystem_csr_path=subsystem.csr
pki_sslserver_csr_path=sslserver.csr
pki_audit_signing_csr_path=ocsp_audit_signing.csr
pki_admin_csr_path=ocsp_admin.csr

Specify the certificate files with the following parameters:

pki_ocsp_signing_cert_path=ocsp_signing.crt
pki_subsystem_cert_path=subsystem.crt
pki_sslserver_cert_path=sslserver.crt
pki_audit_signing_cert_path=ocsp_audit_signing.crt
pki_admin_cert_path=ocsp_admin.crt

Each certificate file can contain either a single PEM certificate or a PKCS #7 certificate chain.

If all of the above certificate files contain single certificates, the CA signing certificate and/or the certificate chain can be specified with the following parameters:

pki_ca_signing_nickname=ca_signing
pki_ca_signing_cert_path=ca_signing.crt
pki_cert_chain_nickname=cert_chain
pki_cert_chain_path=cert_chain.p7b

The CA signing certificate and the certificate chain file can contain either a single certificate or a PKCS #7 certificate chain as well.

Finally, execute the following command:

$ pkispawn -f ocsp-step2.cfg -s OCSP

Verification

On the CA, verify that the OCSP is added into the security domain with the following command:

$ pki -c Secret.123 -n caadmin securitydomain-show

  Domain: EXAMPLE

  CA Subsystem:

    Host ID: CA <CA hostname> 8443
    Hostname: <CA hostname>
    Port: 8080
    Secure Port: 8443
    Domain Manager: TRUE

  OCSP Subsystem:

    Host ID: OCSP <OCSP hostname> 8443
    Hostname: <OCSP hostname>
    Port: 8080
    Secure Port: 8443
    Domain Manager: FALSE

On the OCSP, verify the OCSP admin can access the OCSP. If pki_client_database_purge=False, execute the following command:

$ pki -d ~/.dogtag/pki-tomcat/ocsp/alias -c Secret.123 -n ocspadmin ocsp-user-find

Otherwise, execute the following commands:

$ pki -c Secret.123 client-init
$ pki -c Secret.123 client-cert-import ca_signing --ca-cert ca_signing.crt
$ pki -c Secret.123 client-cert-import \
    --pkcs12 ~/.dogtag/pki-tomcat/ocsp_admin_cert.p12 \
    --pkcs12-password-file ~/.dogtag/pki-tomcat/ocsp/pkcs12_password.conf
$ pki -c Secret.123 -n ocspadmin ocsp-user-find
