You can use Windows Certificate Store to store certificates used for Enterprise Server and Enterprise Central authentication. In this case you do not use WorkStation for the storage functions. Instead you use Certmgr.exe, Windows Certificate Manager Tool.
However, WorkStation is still used for activating the certificates you want to use.
Certificates with Elliptic Curve Cryptography (ECC cipher / encryption) are supported when authorizing servers in EcoStruxure Building Operation.
Use this workflow to import and activate certificates in Windows Certificate Store.
