When you first open Certificate Management on a platform or station (JACE or Supervisor), NiagaraAX 3.8 automatically creates the certManagement folder under the niagara folder (at the same level as the licenses and modules folders). You use this location to temporarily store certificate requests (CSRs), as well as intermediate and server certificate .pem files.

Versions of NiagaraAX prior to 3.8 do not automatically create the certManagement folder. Earlier versions leave it up to you to create a folder structure to hold your CSR and .pem files.

Do not confuse certManagement with the certificates folder, which is part of confirming your NiagaraAX license.

If you are upgrading to version 3.8 from a previous version of NiagaraAX, you may cut your previous folder structure and paste it into the automatically-created certManagement folder.

Certificates created under previous versions of NiagaraAX may or may not be usable in the new version.

Delete any certificate request (.csr) files once you receive the signed certificates.

Do not store certificate files that contain private keys in this or any other folder structure on a computer that is located in an unprotected area.
