Hi everybody, I 'm a wowza newbie.

I read some articles about DRM, but it just say about DRM encryption.

What about DRM authentication? May I use a CA server for Wowza DRM authentication?

Thank all.

Hi,

Can you please give us more details about the workflow you are trying to implement?

Wowza DRM addon provides integration with third party Digital Rights Management key management systems to add on-the-fly encryption for live and video on demand workflows. Currently the DRM systems that are supported are BuyDRM™, EZDRM and Verimatrix® VCAS™

You can find more details in our [Wowza DRM addon overview](https://www.wowza.com/docs/wowza-drm) article.
