PKI 10.5 Installing KRA Clone

Endi S. Dewata edited this page Dec 15, 2021 · 1 revision

Overview

A CA supports multiple KRA instances, but the additional KRA instances have to be installed as clones.

Creating DS Instance

Install a DS instance for the CA clone.

If SSL is enabled on DS master, the DS clone must be configured with SSL too. Make sure the DS master and clone trust each other’s certificates.

Exporting KRA System Certificates

Dogtag 10.3 or newer

Export KRA system certificates with the following command:

$ pki-server kra-clone-prepare --pkcs12-file kra-certs.p12 --pkcs12-password Secret.123

If necessary, third-party certificates (e.g. other trust anchors) can be added into the same PKCS #12 file with the following command:

$ pki -d /var/lib/pki/pki-tomcat/alias pkcs12-cert-add <nickname> --pkcs12-file kra-certs.p12 --pkcs12-password Secret.123

Dogtag 10.2 or older

Copy the NSS database password into a file:

$ grep "internal=" /var/lib/pki/pki-tomcat/conf/password.conf | awk -F= '{print $2}' > internal.txt

Export all system certificates (including KRA system certificates) into a PKCS #12 file:

$ PKCS12Export -debug \
    -d /var/lib/pki/pki-tomcat/alias \
    -p internal.txt \
    -o kra-certs.p12 \
    -w ~/.dogtag/pki-tomcat/ca/pkcs12_password.conf

Transfer the file to the clone. The clone will import only the certificates and keys needed by the clone.

Verification

Make sure the PKCS #12 file contains at least the following KRA system certificates:

$ pki pkcs12-cert-find --pkcs12-file kra-certs.p12 --pkcs12-password-file password.txt

Installing KRA Clone

Transfer the PKCS #12 file to the clone, then prepare a deployment configuration file (e.g. kra-clone.cfg):

[KRA]
pki_admin_email=kraadmin@example.com
pki_admin_name=kraadmin
pki_admin_nickname=kraadmin
pki_admin_password=Secret.123
pki_admin_uid=kraadmin

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

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

pki_security_domain_hostname=master.example.com
pki_security_domain_https_port=8443
pki_security_domain_user=caadmin
pki_security_domain_password=Secret.123

pki_clone=True
pki_clone_replicate_schema=True
pki_clone_uri=https://master.example.com:8443

# Dogtag 10.2 or older
pki_clone_pkcs12_path=/tmp/kra-certs.p12
pki_clone_pkcs12_password=Secret.123

# Dogtag 10.3 or newer
pki_server_pkcs12_path=/tmp/kra-certs.p12
pki_server_pkcs12_password=Secret.123

If necessary, specify the certificate nicknames in the following parameters to match the nicknames in the PKCS #12 file:

pki_storage_nickname=kra_storage
pki_transport_nickname=kra_transport
pki_audit_signing_nickname=kra_audit_signing
pki_ssl_server_nickname=sslserver
pki_subsystem_nickname=subsystem

By default it will use the CA running on the security domain. To use a different CA, add the following parameter:

pki_issuing_ca_hostname=clone.example.com

Begin the installation:

$ pkispawn -v -f kra-clone.cfg -s KRA

Verification

Verify certificates

The certificates should have the same nicknames and trust flags as in the master:

$ certutil -L -d /var/lib/pki/pki-tomcat/alias

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

ca_signing                                                   CTu,Cu,Cu
kra_storage                                                  u,u,u
sslserver                                                    u,u,u
subsystem                                                    u,u,u
kra_audit_signing                                            u,u,Pu
kra_transport                                                u,u,u

Verify keys

The keys should have the same IDs as in the master except for the SSL server key:

$ sed -n "/^internal=/ s/^[^=]*=// p" < /var/lib/pki/pki-tomcat/conf/password.conf > internal.txt
$ certutil -K -d /var/lib/pki/pki-tomcat/alias -f internal.txt
