About Adobe Primetime DRM credentials
If you want to issue valid licenses that a Primetime DRM client can accpt, then you must configure the Primetime DRM Server for Protected Streaming with a set of credentials that Adobe has issued. You can store these credentials in PKCS#12 (.pfx) files or on an HSM.
The .pfx files can be located in any directory that you select. However, Adobe recommends that you locate the .pfx files in the tenant's configuration directory for ease of access.
