Looking to implement HLS with a rotating key for live streaming. Haven’t been able to find anything regarding Wowza’s capabilities to handle this. Is my google-fu too weak, or has this topic not been broached?
Thanks,
-Mike

Mike,
What do you mean by “rotating links”?
A user posted this method of doing expiring iinks that could be adapted to HLS streaming:
[Custom stream authorization and expiration module (all methods?)](http://community.wowza.com/t/-/33555))

There is currently not a way to do rotating keys. If you use the internal AES-128 method and stop the encoder for 30 seconds and start the encoder you can change the keys but it would cause a break in the stream.

Mike,
I don’t think there is a way to do that.

Sorry for the ambiguity, I will elaborate. Using AES encryption for the chunk files, as described here:
[https://www.wowza.com/docs/how-to-secure-apple-http-live-streaming-aes-128-external-method](https://www.wowza.com/docs/how-to-secure-apple-http-live-streaming-aes-128-external-method))
However, I would like to have the key regenerated and applied every n chunks. Does that make sense?
Thanks,
-Mike
