Generating a New Self-Signed Certificate

If you are upgrading to HMG/HSG version 3.2 or greater, due to a new restriction of TLS certificates in certain operating systems, a new self-signed certificate with a 2-year expiration should be generated after the upgrade.

  3. Click the Generate button.
  4. On the Generate Certificate or Private Key dialog:
    1. Type in a name for the certificate.
    2. For the Type, select Self-Signed.
    3. Fill in the remaining fields. See Certificate Settings.
    4. Click the Apply button.
  5. The new certificate is added to the Certificates list.
  6. Select the new certificate in the Active column to activate it.
  7. Optionally, delete the old certificate.
  8. Click Reboot for the change to take effect.
