Installing CA Clone with HSM
============================

Overview
--------

This page describes the process to install a CA subsystem as a clone of an existing CA subsystem
where the system certificates and their keys are stored in HSM.

Since the certificates and the keys are already in HSM, it's not necessary to export them into a
PKCS #12 file to create a clone.

CA Subsystem Installation
-------------------------

Prepare a file (e.g. ca.cfg) that contains the deployment configuration, for example:

```
[DEFAULT]
pki_server_database_password=Secret.123

pki_hsm_enable=True
pki_hsm_libfile=/usr/lib64/pkcs11/libsofthsm2.so
pki_hsm_modulename=softhsm
pki_token_name=token
pki_token_password=Secret.123

[CA]
pki_admin_email=caadmin@example.com
pki_admin_name=caadmin
pki_admin_nickname=caadmin
pki_admin_password=Secret.123
pki_admin_uid=caadmin

pki_client_pkcs12_password=Secret.123

pki_ds_base_dn=dc=ca,dc=pki,dc=example,dc=com
pki_ds_database=ca
pki_ds_password=Secret.123

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

pki_ca_signing_nickname=ca_signing
pki_ocsp_signing_nickname=ca_ocsp_signing
pki_audit_signing_nickname=ca_audit_signing
pki_sslserver_nickname=sslserver/replica.example.com
pki_subsystem_nickname=subsystem

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

Then execute the following command:

```
$ pkispawn -f ca.cfg -s CA
```

It will install CA subsystem in a Tomcat instance (default is pki-tomcat) and create the following NSS databases:
* server NSS database: /etc/pki/pki-tomcat/alias
* admin NSS database: ~/.dogtag/pki-tomcat/ca/alias

Verifying System Certificates
-----------------------------

Verify that the internal token contains the following certificates:

```
$ certutil -L -d /etc/pki/pki-tomcat/alias

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

ca_signing                                                   CT,C,C
ca_audit_signing                                             ,,P
```

Verify that the HSM contains the following certificates:

```
$ certutil -L -d /etc/pki/pki-tomcat/alias -h token -f token.pwd

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

token:ca_signing                                             CTu,Cu,Cu
token:ca_ocsp_signing                                        u,u,u
token:subsystem                                              u,u,u
token:ca_audit_signing                                       u,u,Pu
token:sslserver/replica.example.com                          u,u,u
```

Verifying Admin Certificate
---------------------------

Prepare a client NSS database (e.g. ~/.dogtag/nssdb):

```
$ pki -c Secret.123 client-init
```

Import the CA signing certificate:

```
$ pki -c Secret.123 client-cert-import ca_signing --ca-cert ca_signing.crt
```

Import the master's admin key and certificate:

```
$ pki -c Secret.123 client-cert-import \
    --pkcs12 ca_admin_cert.p12 \
    --pkcs12-password Secret.123
```

Verify that the admin certificate can be used to access the CA clone by executing the following command:

```
$ pki -c Secret.123 -n caadmin ca-user-show caadmin
--------------
User "caadmin"
--------------
  User ID: caadmin
  Full name: caadmin
  Email: caadmin@example.com
  Type: adminType
  State: 1
```
