BasicAESClearKey

Dynamically encrypt your content with AES-128

This sample demonstrates how to dynamically encrypt your content with AES-128. It shows how to perform the following tasks:

1. Creates a transform with built-in content aware encoding preset
2. Submits a job
3. Creates a ContentKeyPolicy using a secret key
4. Associates the ContentKeyPolicy with StreamingLocator
5. Gets a token and print a url for playback

When a stream is requested by a player, Media Services uses the specified key to dynamically encrypt your content with AES-128 and Azure Media Player uses the token to decrypt.
