I’m trying to enable offline playback of DRM protected content on iOS devices. as per apple documentation it requires **EXT-X-SESSION-KEY** tag in playlist to persist / pre-fetch all the keys
can anyone help me how to set this up in wowza streaming engine?

You’re welcome. Sorry for the delay- the engineers are looking into an alternative for you since we don’t yet support the EXT-X-SESSION-KEY. But, I will post again when I have an option for you to try…probably by the end of the day @Harshal Khairnar.

Apologies @sudharsan thiru, we do not support the EXT-X-SESSION-KEY at this time.
In the meantime, you can look into implementing a custom workflow where you can create your own playlists using a custom Apple HLS stream target.
[https://github.com/WowzaMediaSystems/wse-example-pushpublish-hls](https://github.com/WowzaMediaSystems/wse-example-pushpublish-hls)
You can alternatively create the playlist.m3u8 file only using third-party tools, and have it reference the chunklist URI in the playlist generated by Wowza.
Players would initially request this high-level manifest file with the EXT-X-SESSION-KEY tag, and then request the chunklist.m3u8 URI found in the high-level manifest.
The request for this feature has been submitted to the Engine team.
