View source for Setting up two Thales CipherTrust Cloud Key Manager (CCKM) Appliances inside OCI, create a cluster between them and configure one of them as Certificate Authority (CA)

= Introduction =

Organizations increasingly seek greater control over their cryptographic keys in today's cloud-first landscape to meet security, compliance, and data sovereignty requirements. '''Thales CipherTrust Cloud Key Manager (CCKM)''' offers a centralized solution for managing encryption keys and secrets across multi-cloud and hybrid environments—including Oracle Cloud Infrastructure (OCI). A key feature of this architecture is support for '''Hold Your Own Key (HYOK)''', allowing you to retain complete control over your encryption keys even when using third-party cloud services.

This tutorial walks you through the complete setup of '''two Thales CCKM appliances inside OCI''', including:

* Deploying two CCKM instances
* Creating a '''high-availability cluster''' between them
* Configuring one of the appliances as a '''Certificate Authority (CA)''' for issuing and managing internal certificates

By the end of this guide, you will have a robust and scalable CCKM environment that supports key use cases such as '''BYOK''' (Bring Your Own Key), '''HYOK''', and centralized key lifecycle management. This setup is ideal for enterprises looking to extend their key control into the cloud while adhering to the highest data security standards.

= STEP 01 - Review the OCI VCN Infrastructure =

Before deploying the Thales CipherTrust Cloud Key Manager (CCKM) appliances, it's essential to understand the underlying Oracle Cloud Infrastructure (OCI) network architecture that will support them.

In this setup, we are using '''two separate Virtual Cloud Networks (VCNs)''':

* One VCN is in the '''Amsterdam (AMS)''' OCI region.
* The other VCN is in the '''Ashburn (ASH)''' OCI region.

These two regions are connected via a '''Remote Peering Connection (RPC)''', enabling secure and low-latency communication between the CCKM appliances across regions. This cross-region connectivity is essential for high availability, redundancy, and clustering of the CCKMs.

The CCKM appliances will be deployed in '''public subnets''' within each VCN for this tutorial. This approach simplifies initial access and management over the internet—for example, through SSH or the web interface. However, it's important to note that '''best practice in production environments''' is to deploy these appliances in '''private subnets''' and manage access through a '''bastion host''' or a '''stepstone (jump) server'''. This reduces the exposure of the appliances to the public internet and aligns with a more secure network posture.

We'll deploy the CCKMs within this reviewed VCN setup in the next step.

= STEP 02 - Deploy the first Thales CipherTrust Cloud Key Manager -CCKM- Appliance =

* Official Thales documentation for CCKM version 2.19: [[https://thalesdocs.com/ctp/cm/2.19/get_started/deployment/virtual-deployment/oracle-cloud-deployment/index.html Oracle Cloud Deployment]]

Before deploying the first Thales CipherTrust Cloud Key Manager (CCKM) appliance, we must ensure the required image is available in Oracle Cloud Infrastructure (OCI).

While the official Thales documentation typically recommends opening a support case to obtain an '''Object Storage URL''' for directly importing the CCKM image into OCI, we'll be using an alternative method.

We've received a local '''.ova file''' from Thales (<code>610-000612-025_SW_VMware_CipherTrust_Manager_v2.19.0_RevA.ova</code>). Instead of using the provided URL, we will:

# '''Extract the <code>.vmdk</code> file''' from the <code>.ova</code> archive
# '''Upload the <code>.vmdk</code> file''' to an OCI Object Storage bucket
# '''Create a custom image''' in OCI from the <code>.vmdk</code> file
# '''Deploy the CCKM instance''' using this custom image

This method gives us complete control over the image import process and is especially useful in air-gapped or custom deployment scenarios.

* Store the <code>610-000612-025_SW_VMware_CipherTrust_Manager_v2.19.0_RevA.ova</code> file inside a new folder on the local disk.

[[File:a60ae676bb82b2f93864a785da983ca8.png|800px]]

= STEP 03 - Do the initial configuration on the first Thales CipherTrust Cloud Key Manager -CCKM- Appliance =

Now that the first CCKM appliance is deployed and accessible, it's time to perform the initial configuration. This includes setting up the system clock using an NTP server and activating the evaluation license or the actual license provided by Thales.

These steps ensure the appliance is operating with accurate time—critical for certificate management, logging, and synchronization—and is fully functional during the evaluation or setup phase.

* Navigate to: '''Admin Settings''' → '''NTP'''
* Select '''Add NTP Server'''

[[File:dc3d7c810b46db9ac3be803a40dc2103.png|800px]]

[[File:560f844e85f7fd599fc7dcf97135b7ba.png|800px]]

= STEP 05 - Review the connection between the Thales CipherTrust Cloud Key Manager -CCKM- Appliances with RPC =

To prepare for high availability and clustering between the two Thales CipherTrust Cloud Key Manager (CCKM) appliances, it's essential to ensure proper connectivity between the regions in which they are deployed.

In our setup, a '''Remote Peering Connection (RPC)''' has been established between the '''Amsterdam (AMS)''' and '''Ashburn (ASH)''' OCI regions. This RPC enables secure, low-latency communication between the two VCNs where each CCKM appliance resides.

'''What Has Been Configured:'''
* '''Remote Peering Connection (RPC)''' is established and active between AMS and ASH.
* '''Routing tables''' are appropriately configured to ensure traffic between the two VCNs is forwarded correctly.
* '''Security lists''' in both regions are currently configured to allow '''all ingress and egress traffic'''.
* This is done to simplify Proof of Concept (PoC) testing and eliminate connectivity-related issues during the initial setup and clustering process.


{{note|
In a production environment, it is strongly recommended to restrict traffic to only the required ports for clustering and management. 
Refer to Thales documentation for the exact port requirements (e.g., TCP ports like 443, 8443, 5432, and others used by the CCKM cluster protocol).
}}

This cross-region network setup ensures that the CCKMs can communicate seamlessly during the cluster creation process, which we'll address in one of the following sections.

[[File:9815d91e24c347852171be667519207b.png|800px]]

= STEP 06 - DNS Configuration =

* Official OCI documentation: [[https://docs.oracle.com/en-us/iaas/Content/DNS/Tasks/create-private-zone.htm Creating a Private DNS Zone]]

Proper DNS resolution is required to enable seamless communication between the two appliances. This is especially important for secure clustering, certificate handling, and overall service stability.

{{note|
From this point forward, we will refer to the '''Thales CipherTrust Cloud Key Manager (CCKM)''' appliances as '''CTM''', short for '''Cyber Trust Manager'''.
}}

While using a '''custom internal DNS server''' is possible, we are leveraging '''Oracle Cloud Infrastructure (OCI) DNS Services''' with a '''private DNS zone''' in this deployment. This allows us to assign meaningful, Fully Qualified Domain Names (FQDNs) to the CTMs and ensures they can communicate across regions without relying on static IPs.

* '''Private DNS Zone Name''': <code>oci-thales.lab</code>
* '''Scope''': Private
* '''Associated VCNs''': Both '''AMS''' and '''ASH''' VCNs (to allow cross-region name resolution)

We've created two A records within the <code>oci-thales.lab</code> zone, pointing to the private IPs of each CTM appliance:
{| class="wikitable"
! Hostname !! FQDN !! Points to
|-
| <code>ctm1</code> || <code>ctm1.oci-thales.lab</code> || Private IP of CTM in AMS
|-
| <code>ctm2</code> || <code>ctm2.oci-thales.lab</code> || Private IP of CTM in ASH
|}
Using FQDNs makes managing certificates and cluster configurations easier and avoids coupling the configuration to fixed IPs.

= STEP 07 - Configure the first Thales CipherTrust Cloud Key Manager -CCKM- Appliance as a Certificate Authority -CA- =

* Official Thales documentation for CCKM version 2.19: [[https://thalesdocs.com/ctp/cm/2.19/admin/cm_admin/local-ca/index.html Certificate Authority]]

The first time a CipherTrust Manager is started, a new local <code>CipherTrust Manager Root CA</code> is automatically generated. This CA is used to issue initial server certificates for the interfaces available in the system.
So there is no need to create a new one.

* Make sure you are on the AMS CTM.
* Click on the '''CA Menu'''
* Select '''Local'''
* Review the local automatically generated CA (CipherTrust Manager Root CA) we will use to create and sign CSRs.

= STEP 08 - Create a CSR for both Thales CipherTrust Cloud Key Manager -CCKM- Appliances and sign them by the CA =

* Official Thales documentation: [[https://thalesdocs.com/ctp/ig/openpgp/pgp/pgp_advanced_topics/pgp-setting_ssl/index.html#creating-a-csr-on-the-console Creating a CSR on the Console]]‌‌
* Official Thales documentation: [[https://thalesdocs.com/ctp/ig/openpgp/pgp/pgp_advanced_topics/pgp-setting_ssl/index.html#signing-a-certificate-request-with-a-local-ca Signing a Certificate Request with a Local CA]]
* Official Thales documentation for CCKM version 2.19: [[https://thalesdocs.com/ctp/cm/2.19/admin/cte_ag/cte-cert-renewal/index.html#web-interface-certificate-renewal Web Interface Certificate Renewal]]

With both '''Cyber Trust Manager (CTM)''' appliances deployed and DNS configured, it's time to enable secure, certificate-based communication between them. Since the '''AMS CTM and ASH''' are configured as the '''Certificate Authority (CA)''', we will use the '''AMS CTM''' to generate and sign certificates for both appliances.

* The high-level steps will be:
* Generate '''Certificate Signing Requests (CSRs)''' for CTMs (AMS and ASH) on the AMS CTM.
* Use the AMS CTM CA to '''sign both CSRs'''
* Install the signed certificate on each CTM

This ensures all CTM-to-CTM communication is '''trusted and encrypted''', a critical requirement for cluster formation and secure API access.

Perform these steps only on the '''AMS CTM'''.

* Log in to the CTM AMS web interface
* Navigate to: '''CA''' → '''CSR Generator'''

* Fill out the CSR form:
* Select: '''Generic CSR'''.
** '''Common Name (CN)''': Use the CTM’s FQDN (e.g., <code>ctm1.oci-thales.lab</code>)
* '''Display Name''': Use a name (e.g., <code>CTM1 (AMS)</code>)
* '''Algorithm''': ECDSA
* '''Size''': 256
** '''Subject Alternative Name (SAN)''': Also include the FQDN here (e.g., <code>ctm1.oci-thales.lab</code>)
* Click '''Generate CSR and download Private Key'''
* Note that the Private Key will be automatically downloaded.
* Scroll down.

[[File:21640b125e46a4f875cda29f7510be1e.png|800px]]

* Click on '''Download CSR''' to download and save the generated <code>.csr</code> file.

[[File:a1629261c677e56f1a8265b91cf1fca5.png|800px]]

* Repeat the same steps (still on the CTM AMS CA).

* Fill out the CSR form:
* Select: '''Generic CSR'''.
** '''Common Name (CN)''': Use the CTM’s FQDN (e.g., <code>ctm2.oci-thales.lab</code>)
* '''Display Name''': Use a name (e.g., <code>CTM2 (AMS)</code>)
* '''Algorithm''': ECDSA
* '''Size''': 256
** '''Subject Alternative Name (SAN)''': Also include the FQDN here (e.g., <code>ctm2.oci-thales.lab</code>)
* Click '''Generate CSR and download Private Key'''
* Note that the Private Key will be automatically downloaded.
* Scroll down.

[[File:c671facd8b1f94ea0fc916d95564235b.png|800px]]

* Click on '''Download CSR''' to download and save the generated <code>.csr</code> file.

To keep track of the generated '''Certificate Signing Requests (CSRs)''' and '''private keys''', creating a clean folder structure on your local machine or a secure admin server is a good practice.

Here's a simple example structure that I have used.

[[File:e42973b725c8ee1c37bca768e8cb70bb.png|800px]]

Navigate to: '''CA''' → '''Local'''.
Select the CA.

[[File:a7c060b5eeb2499fc526b21ffa5d4ad6.png|800px]]

Click '''Upload CSR'''.

[[File:8835650f533c00117eeac4bacac58683.png|800px]]

* '''Display Name''': Use the CTM’s FQDN (e.g., <code>ctm1.oci-thales.lab</code>)
* Copy the content of the generated CSR in the CSR field.

[[File:e974ce3daf88043c74f83a8f9f9e4d82.png|800px]]

* '''Certificate Purpose''': Server.
* Click '''Issue Certificate'''.

[[File:e3eb828a93382c880091e12116d50d03.png|800px]]

* Click on the three dots at the end of the signed certificate entry.
* Click on download to download the signed certificate for CTM1.

[[File:48d06a7768d5dac69e7d42dade623b24.png|800px]]

* Repeat the same steps (still on the CTM AMS CA).

* '''Display Name''': Use the CTM’s FQDN (e.g., <code>ctm2.oci-thales.lab</code>)
* Copy the content of the generated CSR in the CSR field.

[[File:a7c1cb677661db7d835219d5249b6fbc.png|800px]]

* '''Certificate Purpose''': Server.
* Click '''Issue Certificate'''.

[[File:21ee554fedc62c170e06450ec98d5108.png|800px]]

* Click on the three dots at the end of the signed certificate entry.
* Click on download to download the signed certificate for CTM2.

[[File:ed35cbeb65468bba0be992b2f035a0fb.png|800px]]

* Rename and store the signed certificates in the created folder structure.

[[File:af35c141c2cf7b065f158b4d467d855b.png|800px]]

In addition to signing the individual CTM certificates, the '''CA Root Certificate''' is a critical piece of the trust chain. This root certificate establishes the foundation of trust for all certificates issued by your CTM, acting as the Certificate Authority (CA).

* Navigate to:  '''CA''' → '''Local'''.
* Click on the three dots at the end of the CTM AMS CA.
* Click on download to download the Root CA certificate of CTM AMS CA.

[[File:afc68dd923367732ffd48de5e23f889f.png|800px]]

* Store the downloaded root cert in the created folder structure.

[[File:814b5abacfae0841a5e9bdf51d3febf5.png|800px]]

* The next step is to create a '''full certificate chain file''' that bundles your signed certificate, the CA root certificate, and your private key into a single file.
* This is required by applications or appliances like CTM for seamless TLS configuration.

{{console|body=

-----BEGIN CERTIFICATE-----
Signed CTM1 Cert by CA
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
Root CA Cert
-----END CERTIFICATE-----
-----BEGIN EC PRIVATE KEY-----
Private Key
-----END EC PRIVATE KEY-----

}}

* Do this for BOTH CTMs.
* Store the newly concatenated certificate files in the created folder structure.

[[File:d4deed052c3fff68be0ecc0e13df6425.png|800px]]

* After creating the signed certificates on the CA and preparing the complete certificate chain files, the next step is to upload them to each CTM appliance.
* Let's start with the first CTM1 running in AMS.

* Navigate to:  '''Admin Settings''' → '''Interfaces'''.
* Click on the three dots of the web interface.
* Select '''Renewal Certificate Options'''.

[[File:a69fcd5e3dcdb2c4a878ccd22d8c63fa.png|800px]]

* Select '''Upload/Generate'''.
* Click on '''Ok'''.

[[File:fd71951d14233d6f4a8548a8c1599fe5.png|800px]]

* Upload the Full chain cert for CTM1 using the PEM format.
* Click on '''Upload Certificate'''.

[[File:efeb7091e7b98b3dfd1025f1ea31301b.png|800px]]

* Click on the three dots of the web interface (again).
* Select '''Renewal Certificate Options''' (again).

[[File:92cd5d42c72aa95d80794fe8690f45b2.png|800px]]

* Select '''Apply'''.
* Click on '''Ok'''.

[[File:3d5c552507d0b21409f13443a2599ac6.png|800px]]

* Click on '''Apply'''.

[[File:7666b37e5c844c51c2fc8864cfd2f4ff.png|800px]]

* Click on '''Services Page'''.

[[File:7208118382aab03b205482dc20013317.png|800px]]

* Click on '''System Restart'''.

[[File:7703c457ce519a9daf3d5fb653d9b86f.png|800px]]

* Click on '''Restart Services''' to restart the server + web services to activate the new certificate.

[[File:56751892d1b8f1ac116e7289264c3257.png|800px]]

* '''REPEAT THE SAME STEPS for CTM2 running in ASH.'''

* To test the newly signed certificate in your local environment using Chrome, you first need to install it and its CA chain into your operating system's trusted certificate store.
* This is out of the scope of this tutorial, but I will show you how I tested the new CTM certificates signed by the CTM AMS CA.

* Open the Google Chrome browser settings.
* Navigate to the '''Privacy and Security''' tab.
* Click on '''Security'''.

[[File:4991cb27b3522a002a80480ece94506a.png|800px]]

* Click on '''Manage certificates'''.

[[File:401ebba50b6a43c11e08f4b6929ecebe.png|800px]]

* Click on '''Local certificates'''.
* In the custom section, click on '''Installed by you'''.

[[File:b5800f2dc44c0c401d51fc55acc2030a.png|800px]]

* I have already imported the full chain certs + Root cert on my local OS.
* This is also where you can import the certificates; this button will bring you to the OS-level certificate settings.

[[File:374740c7de9f1a96882718d0882aa5c6.png|800px]]

* Because I have not configured the DNS server on the internet, I am updating my local <code>/etc/hosts </code>file with the manual host entries to test the certificates from my local machine using the FQDN.

[[File:0dbb35510f241ebfc94cd8c390e8e17f.png|800px]]

* Browse to the CTM1 FQDN using Google Chrome.
* Click on the security settings.

[[File:87556d7395743200e85ce8d979056e39.png|800px]]

* Click on '''Connection is secure'''.

[[File:1d350a898b1d5ffca80137c6a3667698.png|800px]]

* Click on '''Certificate is valid'''.

[[File:0400d9e7983f9ba27ebb3a3b1ffd3bf5.png|800px]]

= STEP 09 - Configure Thales CipherTrust Cloud Key Manager -CCKM- Appliance Clustering =

* Official Thales documentation for CCKM version 2.19: [[https://thalesdocs.com/ctp/cm/2.19/admin/cm_admin/clusters-and-nodes/index.html#creating-a-new-cluster-configuration Creating a New Cluster Configuration]]

* Clustering Thales CipherTrust Cloud Key Manager (CTM) appliances enables high availability and load balancing for cryptographic key management.
* This ensures continuous service and fault tolerance in your security infrastructure.
* Clustering is configured entirely from the management console of a single (primary) CTM appliance (in our case, the CTM running in AMS).
* Use this appliance's interface to create the cluster and add other CTM appliances as cluster nodes.

* Navigate to:  '''Admin Settings''' → '''Cluster'''.
* Click on '''Manage Cluster'''.

[[File:504bf6fb9f4dcc1d8a388726e97a82f2.png|800px]]

* Click on '''Next'''.

[[File:7372775893d62e32257d12a3dd7a3789.png|800px]]

* Type in the hostname of the AMS CTM (which is the CTM1 in AMS  with private IP '''10.222.10.111''').
* I do not intend to use (or create) a cluster over the internet using the public IP, so I am using the private IP address in both fields.
* Click on '''Add Cluster'''.

[[File:d2d29585491d5e3354e09ac248d8d8f9.png|800px]]

* Notice that this machine has created a new cluster and is part of its cluster.

[[File:594d6f4bd15694232633de90d8e30b5e.png|800px]]

* On the same AMS CTM1 click on '''Manage Cluster''' (again).
* Select '''Add Node''' (to add the ASH CTM2).

[[File:cd07c88974008ae9205d66af8bc790bf.png|800px]]

* Specify the ASH CTM IP address as the nod to add to the cluster.
* I could have used the DNS name here, but I did not.
* Click on '''Add Node'''

[[File:9a77c502beda7439b609e164fd9c1b7b.png|800px]]

* A new browser window/tab will be opened to the ASH CMT2.
* If you are not logged in to the ASH CMT2, you might get a login prompt first.
* Some cluster configuration activity will happen in the background.

[[File:54a14fd9460e016fcf85e0c83cd33a9a.png|800px]]

* Confirm the join by clicking on '''Join'''.

[[File:90fe9606380be4bc38c6e2c4fa88f5c0.png|800px]]

* Some more cluster configuration activity will happen in the background.

* Confirm the Success message by clicking on '''Finish!'''.

[[File:55b699ae77a2e26e7727140709fcdb12.png|800px]]

* If the newly opened browser window/tab is still open, you can close it manually.

[[File:9f2441903062d2721d3b66517a13a38a.png|800px]]

* On the AMS CTM1 also confirm by clicking on '''Finished'''.

[[File:f659a285b7c94c5011f7cc4a4940a0b5.png|800px]]

* At first, the newly added node (ASH CTM2) will appear down.
* Wait for a few minutes so the cluster can detect its presence.

[[File:61be368395dd65ee9e88d9111946a2de.png|800px]]

* You might also see an error message at the top of the screen.
* This means that the cluster is still in configuration mode.
* Wait a few minutes for the message to disappear.

[[File:638c2bdef57605eebc1de838e1873ca8.png|800px]]

To verify if the CTM Cluster configuration is done correctly and is healthy, you can check CTM1 and CTM2.

From CTM1:
* Navigate to:  '''Admin Settings''' → '''Cluster'''.
* Notice that the IP address 10.222.10.111 is from this server (AMS CTM1).
* Notice the other node (10.111.10.32) from the remote server (ASH CTM2).

[[File:e059143643b3c6dc68fb15a84f37536a.png|800px]]

From CTM2:
* Navigate to:  '''Admin Settings''' → '''Cluster'''.
* Notice that the IP address 10.111.10.32 is from this server (ASH CTM2).
* Notice the other node (10.222.10.111) from the remote server (AMS CTM1).
