Initialize Certificate Chain
Initialize Certificate Chain

Use this section to create a new 2-level CA hierarchy (Root + Intermediate) for a given certificate type and algorithm.

  • Choose the Certificate Type (PQC, Composite, Catalyst) and a signing algorithm that matches your needs.
  • Define a Chain Name – a unique identifier for this CA chain.
  • Provide the Root CA and Intermediate CA Common Names (CN).
  • Once initialized, this chain will appear under Manage Existing Chain and can be later used for user enrollment and verification.
Certificate type

Defines how classical and post-quantum algorithms are combined in the certificate.

  • PQC – contain post-quantum algorithm only.
  • Composite – combine classical and PQC keys and signatures in single structures.
  • Catalyst – rely on certificate extensions to store PQC signature and PQC public key.
Chain Name

A unique identifier used by the application.

  • Choose a unique name for your certificate chain so that it can be referenced in the application
  • You will use this name later to download CA certs, keys, or issue CRLs.
Algorithm Selection

The required Algorithm depends on your certificate type:

  • Single-key algorithms - used for PQC-only certificates.
  • Dual-key algorithms - include a classical key + a PQC key. Required for Composite and Catalyst certificates.

Manage existing certificate chains

Select a previously created chain to download its CA certificates, retrieve CA private keys (if applicable), or generate a new CRL.

  • CA Certs – downloads the Root + Intermediate certificates.
  • CA Keys – downloads the private keys you generated earlier.
  • Issue CRL – creates a new CRL signed by the Intermediate CA.

You must select a chain before performing any of these operations.

CA Certs
User Certificate Enrollment
User Enrollment

Issue end-entity certificates for user, using an existing CA chain.

  • The top form lets you generate a CSR (Certificate Signing Request), optionally with your own keys.
  • You can either let the system generate keys or upload your own key pair(s)
  • The bottom form allows you to upload a CSR and select a CA Chain Identifier to create a signed certificate.
Certificate type

Defines how classical and post-quantum algorithms are combined in the certificate.

  • PQC – contain post-quantum algorithm only.
  • Composite – combine classical and PQC keys and signatures in single structures.
  • Catalyst – rely on certificate extensions to store PQC signature and PQC public key.
Algorithm Selection

The required Algorithm depends on your certificate type:

  • Single-key algorithms - used for PQC-only certificates.
  • Dual-key algorithms - include a classical key + a PQC key. Required for Composite and Catalyst certificates.
Uploading your own keys

The keys you must provide depend on the selected certificate type.

  • PQC – provide only one Post-Quantum key pair.
  • Hybrid – provide two independent key pairs:
    one Classical + one PQC.

If you do not upload keys, the system automatically generates them with the correct algorithms.


Upload CSR File

Select the Certificate Signing Request (CSR) you want to turn into a certificate. Expected format: PEM/DER.

  • Step 1 – Choose the CSR file (PEM or DER) generated by your application or by this page.
  • Step 2 – Select the matching CA Chain Identifier below.
  • The subject and public key come from the CSR; the issuer and signature come from the intermediate CA.
CA Chain Identifier

Choose which CA chain will sign the CSR.

  • Select the CA chain created on the left-hand panel.
  • The application will build the certificate from the CSR data and the private key of the Intermediate CA in this chain.
  • Make sure the selected chain matches the intended certificate type and algorithm.
Verify or Visualize X.509 Objects
Verify or Visualize X.509 Objects

Check signatures and inspect details of X.509 objects such as certificate chain, CSRs and CRLs.

  • Select the Certificate Type and X.509 Object Type you want to analyze.
  • Upload the required file(s) in PEM or DER format (certificate, CSR, CRL + issuer chain).
  • Click Verify to validate the signatures and see a textual result in the Verification Result box.
  • Click Visualize to open a modal with a structured view of the selected object.
Certificate type

Defines how classical and post-quantum algorithms are combined in the certificate.

  • PQC – contain post-quantum algorithm only.
  • Composite – combine classical and PQC keys and signatures in single structures.
  • Catalyst – rely on certificate extensions to store PQC signature and PQC public key.
X.509 Object Type

Choose what kind of X.509 object you want to verify or visualize.

  • Certificate – Upload a PEM/DER certificate to check signature(s).
  • CSR – Upload a CSR to inspect subject data and verify signature(s).
  • CRL – Upload both the CRL and the issuer certificate to validate the CRL’s signature(s).
What should I upload?

The required files depend on the X.509 object type you want to verify and must be in PEM or DER format.

  • Certificate / CertChain – upload a self-signed certificate or a full certificate chain to verify.
  • CSR – upload the CSR file only. The public key(s) extracted from CSR will be used to verify signature(s)
  • CRL – upload both the CRL and the certificate chain (or self-signed certificate) as CRL does not contain CA's public key.
