Create an ACME Directory URL for Signed HTTP Exchange certificates

  1. In your CertCentral account, in the left main menu, select Automation > ACME Directory URLs.

  1. On the ACME Directory URLs page, select Add ACME Directory URL.

  1. In the Add ACME Directory URL popup window, enter an easily identifiable Name for this URL.

  1. In the Product dropdown, select the OV or EV TLS/SSL certificate type you want to issue with the CanSignHttpExchanges extension.

Currently, the CanSignHttpExchanges extension can be included only in OV and EV TLS/SSL certificates.

  1. In the Division dropdown, select a division to associate with certificates issued from this ACME Directory URL.

  1. In the Organization dropdown, select the prevalidated Organization for the issued certificates.

  1. Under Validity period, select Custom length. In the Days box, enter a number from 1 to 90.

Per industry standards, certificates that include the Signed HTTP Exchange extension have a 90-day maximum validity limit.

  1. Expand Additional Certificate Options. Under Certificate profile options, check Include the CanSignHttpExchanges extension in the certificate.

  1. Select Add ACME Directory URL.

  1. In the New ACME Directory URL popup window, copy your unique ACME URL along with the external account binding information, and save it. Use this URL to request your certificate using your ACME client.

    This information is required for your ACME client to procure certificates from CertCentral. It only gets displayed once.

    After copying and saving it somewhere safe, select I understand I will not see this again to dismiss it.

When you generate an ACME Directory URL, it is displayed only once. There is no way to retrieve a lost ACME URL. If you ever lose an ACME URL, you need to revoke the lost URL and generate a new one.

What's next?

Your new ACME Directory URL is added to the list of URLs on the ACME Directory URLs page (in the sidebar menu, select Automation > ACME Directory URLs).

For details about certificates you can order via the ACME Directory URL, select the information icon next to the URL Description.

Before using your ACME client to order your SSL/TLS certificate with the CanSignHttpExchanges extension, make sure you've set up your domain's CAA resource record. You also need to create an ECC CSR for your "Signed HTTP Exchange" certificate order.
