Hi all,

We are trying to implement SecureToken protection in Wowza Streaming Engine.

The way we understood is that we should do something like this:

- sha256(“vod/sample.mp4?mySharedSecret&myTokenPrefixCustomParameter=abcdef&myTokenPrefixendtime=1467904640&myTokenPrefixstarttime=1467804640”)

- The result would be: b70c922b74dee5a94bb1f66e72dc5f6672e8924e9b9eebc38d9c068ae8944007

- Then, we do base64(b70c922b74dee5a94bb1f66e72dc5f6672e8924e9b9eebc38d9c068ae8944007)

- And we use the result of base64 as value for “myTokenPrefixhash” parameter.
