Any DRM available for HLS VOD assets? We would like to encrypt either the chunks so if someone manages to download the .ts files they can’t put them together using editing software. Even better if we can prevent downloaders like real or acatcher youtube from downloading alltogether
Thanks

There are a few options for this.
For encryption:

And to pass the keys securely, set up an SSL:
