Tutorial - Create Post-Quantum Cryptography Hybrid CA Chain
In this tutorial, you will learn how to create a post-quantum cryptography (PQC) hybrid Certificate Authority (CA) chain that uses RSA for the traditional key and Module-Lattice-Based Digital Signature Standard (ML-DSA) also known as Dilithium for the PQC key.
The tutorial covers these steps:
Update the EJBCA container to version 8.3.2 or later
Create crypto tokens for the PQC hybrid Root and Sub CA
Create and configure certificate profiles for the PQC hybrid CAs
Create the PQC hybrid Root CA
Create the PQC hybrid Sub CA
Create certificate profile and end entity profile to issue TLS Server PQC hybrid certificate
Create a PQC hybrid server TLS certificate using EJBCA RA Web
Review the PQC hybrid certificate with OpenSSL
Prerequisites
For this tutorial, EJBCA Community container version 8.3.2 was used.
Before you begin, you need:
A running EJBCA instance with an active certificate authority (CA), certificate profiles, end entity profiles, and roles configured. To get started, see the playlist: Get started with EJBCA and TLS certificates.
Step 1 - Update EJBCA container to version 8.3.2 or later
PQC hybrid certificates were introduced as a new feature in EJBCA 8.3 and to use this feature the tag for the EJBCA container must be using 8.3.2 or greater. Follow the applicable section below to upgrade the EJBCA container.
Update Docker Compose file and start the containers
If EJBCA is deployed using Docker, follow these steps to upgrade the EJBCA container:
Use SSH to access the Docker server.
Change directory to the docker compose file.
BASH$ cd ~/containersUse a text editor to edit the
docker-compose.ymlfile.BASH$ vim docker-compose.ymlUpdate the container image tag to 8.3.2 or later.
YAMLversion: '3' networks: access-bridge: driver: bridge application-bridge: driver: bridge services: ejbca-database: container_name: ejbca-database image: "library/mariadb:latest" networks: - application-bridge volumes: - ./datadbdir:/var/lib/mysql:rw ejbca-node1: hostname: ejbca-node1 container_name: ejbca image: keyfactor/ejbca-ce:8.3.2 depends_on: - ejbca-database networks: - access-bridge - application-bridge environment: - DATABASE_JDBC_URL=jdbc:mariadb://ejbca-database:3306/ejbca?characterEncoding=UTF-8 - LOG_LEVEL_APP=INFO - LOG_LEVEL_SERVER=INFO - TLS_SETUP_ENABLED=simple - OCSP_NON_EXISTING_IS_GOOD=true ports: - "80:8080" - "443:8443"Save and close the file.
Start the EJBCA and MariaDB container with the following command:
BASH$ docker compose up -d
You have now updated the Docker Compose file to use the latest EJBCA container and started the containers. Continue to step 2 which walks through creating the crypto tokens for the PQC hybrid CAs.
Use Helm to update the EJBCA deployment
If EJBCA is deployed in Kubernetes using Helm, follow these steps to upgrade the EJBCA container:
Use SSH to access the Kubernetes server.
Change directory to the k81 where the
ejbca-overrides.yamlfile is located for the EJBCA Helm deployment:BASH$ cd ~/k81Update the image pull policy to Always to download the latest EJBCA container:
BASH$ sed -i s/IfNotPresent/Always/ ejbca-overrides.yamlUse Helm to upgrade the EJBCA deployment to redeploy EJBCA with the latest container:
BASH$ helm upgrade -n ejbca-k8s ejbca-ca ejbca-ce/ejbca-community-helm -f ejbca-overrides.yamlThe output is similar to the following:
BASHRelease "ejbca-ca" has been upgraded. Happy Helming! NAME: ejbca-ca LAST DEPLOYED: Tue Jul 9 13:40:25 2024 NAMESPACE: ejbca-k8s STATUS: deployed REVISION: 2 TEST SUITE: None NOTES: Thank you for installing EJBCA CE! Now that you have deployed EJBCA, you should look over the docs on using EJBCA available here: https://docs.keyfactor.com/ Your release is named ejbca-ca. To learn more about the release, try: $ helm status ejbca-ca $ helm get manifest ejbca-ca
Change the pull policy back to IfNotPresent to prevent EJBCA from upgrading until you are ready to upgrade:
BASH$ sed -i s/Always/IfNotPresent/ ejbca-overrides.yaml
You have now updated the EJBCA deployment using Helm to use the latest EJBCA container. Continue to step 2 which walks through creating the crypto tokens for the PQC hybrid CAs.
Step 2 - Create crypto tokens for the PQC Hybrid Root and Sub CA
Crypto tokens are how you manage keys in EJBCA used by CAs, remote authentication for peering, OCSP signers, and a few other integrations. Before creating a PQC hybrid CA, keys must be generated for the CA to use.
To create crypto tokens for the PQC hybrid CAs, follow these steps:
Go to the EJBCA Administration and click CA Functions > Crypto Tokens.
Click Create new and specify the following on the New Crypto Token page:
Name: Specify a name for the crypto token, in this example, pqcHybridRoot.
Type: Select Soft.
Authentication Code: Enter a password to be used to activate the crypto token if the container is restarted. In this example, foo123.
Click Save to create the crypto token.
Generate the following keys:
In the Name field that says signKey, specify signKeyRsa001, select RSA 4096 for the key size, and then click Generate new key pair to create the keys.
Repeat to create the default encryption key: name the key defaultKeyRsa001, select RSA 4096 for the key size, and then click Generate new key pair.
Repeat to create a test key: name the key testRsaKey, select RSA 1024 for the key size, and then click Generate new key pair.
Last, to create a Dilithium key: name the key signKeyDil001, select DILITHIUM3 for the key size, and then click Generate new key pair.
Click Back to Crypto Token overview.
Next, to create a crypto token for the Sub CE, click Create new and specify the following on the New Crypto Token page:
Name: Specify a name for the crypto token, in this example, pqcHybridSub.
Type: Select Soft.
Auto-activation: Select Use to allow EJBCA to save the password and reapply it after a restart.
Authentication Code: Enter a password to be used to activate the crypto token if the container is restarted. In this example, foo123.
Click Save to create the crypto token.
Generate the following keys using the same naming as for the Root CA crypto token:
In the Name field that says signKey, specify signKeyRsa001, select RSA 4096 for the key size, and then click Generate new key pair to create the keys.
Repeat to create the default encryption key: name the key defaultKeyRsa001, select RSA 4096 for the key size, and then click Generate new key pair.
Repeat to create a test key: name the key testRsaKey, select RSA 1024 for the key size, and then click Generate new key pair.
Last, to create a Dilithium key: name the key signKeyDil001, select DILITHIUM3 for the key size, and then click Generate new key pair.
Click Back to Crypto Token overview.
You have now created two crypto tokens for the PQC Root and Sub CAs and can continue with creating certificate profiles for the PQC hybrid Root CA and Sub CA in the next step.
Step 3 - Create and configure certificate profiles for the PQC Hybrid CAs
With the support of issuing PQC hybrid certificates, new Alternative Signature certificate profile fields were added, see Certificate Profile Fields for more information. These settings must be configured in the certificate profile to create a PQC hybrid CA.
To configure two certificate profiles to support a PQC hybrid certificate, follow these steps:
Continuing from the EJBCA Administration, click CA Functions > Certificate Profiles.
Click Clone next to the ROOTCA certificate profile.
Name the new certificate profile pqcRootCA-15y, and click Create from template.
To edit the profile values to fit your needs, find the newly created pqcRootCA-15y displayed in the list and click Edit.
On the Edit page, update the following:
For Available Key Algorithms, select RSA.
For Available Bit Lengths, select 4096 bits.
For Signature Algorithm, select SHA512withRSAandMGF1.
Enable Alternative Signature by clicking Use.
For Available Alternative Key Algorithms, select DILITHIUM3.
For Alternative Signature Algorithm, select DILITHIUM3.
For Validity or end date of the certificate, enter 15y.

Select Use for CRL Distribution Points.
Select Use for Use CA defined CRL Distribution Point.
Select Use for Authority Information Access.
Select Use for Use CA defined OCSP locator.
Select Use for Use CA defined CA issuer.
Clear Use for LDAP DN order.
Click Save to store the Sub CA certificate profile.
You have now created two new certificate profiles for the PQC hybrid Root and Sub CA. Continue to the next step to create the PQC hybrid Root CA.
Step 4 - Create the PQC Hybrid Root CA
Now that you have already created the crypto tokens and certificate profiles, you can complete this step to create the PQC hybrid Root CA. The steps to create a CA remain largely the same, with the addition of a few extra configuration options in the crypto token section of the CA configuration.
To create a PQC hybrid Root CA, follow these steps:
Continuing from the EJBCA Administration, click CA Functions > Certificate Authorities.
In the Add CA field, enter the name pqcRootRsaCA-G1 and click Create.
On the Create CA page, update the following:
For Crypto Token, select the crypto token pqcHybridRoot (created earlier in Step 2).
For Signature Algorithm, select SHA512withRSAandMGF1.
For Alternative Signing Algorithm, select an algorithm to enable hybrid certificates. In this example, DILITHIUM3.
For Subject DN, enter CN=Hybrid Root CA - G1,O=Keyfactor Community,C=SE.
For Signed By, select Self Signed.
For Certificate Profile, select pqcRootCA-15y.
For Validity, enter 15y.
Clear LDAP DN order.
For CRL Expire Period, enter 1y.
Click Create to create the Root CA.
Next, to configure Default CA defined validation data values to be used:
Configure the Default CRL Distribution Point:
Open a second tab in the browser and go to https://ejbca-node1.ejbca-k8s/ejbca/publicweb/crls.

Scroll down to Default CRL Distribution Point text field, and paste the URL copied from the second tab.
Edit the URL by changing
httpstohttpto ensure the CRL is downloaded via HTTP.
Configure the CA Issuer Default URI:
Go to the third browser tab that is browsing the https://ejbca-node1.ejbca-k8s/ejbca/publicweb/certificates URL, and refresh the page.
Right-click the sKIDHash = DPkj1c+m9O9NRtgVANnoqOgZ+AQ Download link for the
CN=Hybrid Sub CA - G1, O=Keyfactor Community, C=SE, and select Copy Link.
Return to the first tab with the EJBCA Administration, and paste the URL in the CA Issuer Default URI field.
As before, change
httpstohttpin the URL to ensure the CA certificate is downloaded via HTTP.
Enter http://ejbca-node1.ejbca-k8s/ejbca/publicweb/status/ocsp for the OCSP service Default URI.
Click Save at the bottom of the page.
You have now created the PQC hybrid Sub CA and configured the CDP URL, CA certificate and OCSP URL in the AIA extension. Proceed to the next step to configure a certificate profile to issue an end entity.
Step 6 - Create certificate profile and end entity profile to issue TLS Server PQC Hybrid certificate
The CAs are now built and the next step is to create a certificate profile and end entity profile to use to issue an end entity PQC hybrid certificate.
Create certificate profile
To configure the certificate profile, follow these steps:
To configure the certificate profile and end entity profile, follow these steps:
Continuing from the EJBCA Administration, click CA Functions > Certificate Profiles.
Click Clone next to the TLS Server Profile.
Name the new certificate profile pqcTlsServerRsaDil3-90d, and click Create from template.
To edit the profile values to fit your needs, find the newly created pqcTlsServerRsaDil3-90d displayed in the list and click Edit.
On the Edit page, update the following:
For Available Key Algorithms, select RSA.
For Available Bit Lengths., select 2048 bits, 3072 bits, and 4096 bits.
For Signature Algorithm, select SHA256withRSAandMGF1.
Select Use for Alternative Signature.

For Default Certificate Profile and Available Certificate Profiles, select pqcTlsServerRsaDil3-90d.
For Default CA and Available CAs, select pqcSubRsaCA-G1.
Click Save to store the end entity profile.
You have now created the certificate profile and end entity profile to issue a PQC hybrid end entity certificate. Continue to the next step to issue the PQC hybrid certificate.
Step 7 - Create a PQC Hybrid server TLS certificate using RA Web
The RA Web is a quick and simple web interface to manage certificates in EJBCA. Follow the steps below to issue a PQC hybrid server TLS certificate using the RA Web:
Continuing from the EJBCA Administration, click RA Web and click Make New Request.
For Certificate Type, select pqcTlsServer.
For Key-pair generation, select By the CA.
Optional: If you desire a bigger RSA key, then select one of the other options from the Key algorithm list.
For Common Name (CN), enter pqc-servertls.test.
For the Username, enter pqc-servertls.test.
Enter foo123 for Enrollment code and Confirm enrollment code.
Click Download PEM.
You have now issued a PQC hybrid server TLS certificate. Continue to the next step to parse the certificate with OpenSSL.
Step 8 - Review the PQC Hybrid certificate with OpenSSL
OpenSSL is a versatile tool that you can use to parse the PQC hybrid certificate. Although OpenSSL will not recognize hybrid extensions, you can identify and review the Object Identifiers (OIDs) used for the hybrid extensions. To parse the certificate with OpenSSL, follow these steps:
Open a terminal window and change to the download directory where the certificate was downloaded to from the previous step.
Parse the PQC hybrid certificate with OpenSSL:

Review the output, paying attention to the OIDs
2.5.29.73: alternate signature algorithm, and2.5.29.74: the alternate signature.
You have now parsed the PQC hybrid certificate with OpenSSL to review the extensions in the certificate.
Next steps
In this tutorial, you learned how to create a PQC hybrid CA chain and issue a PQC hybrid server TLS certificate. You can now issue some more certificates and try using a PQC hybrid server TLS certificate on a web server.
Here are some next steps we recommend:
