DRM

===

|

Shaka Packager supports fetching encryption keys from Widevine Key Server and
|
||||
PlayReady Key Server. In addition, Shaka Packager also supports Raw Keys, for
|
||||
which keys and key_ids are provided to Shaka Packager directly.

|

Regardless of which key server you are using, you can instruct Shaka Packager to
|
||||
generate other protection systems in additional to the native protection system
|
||||
from the key server. This allows generating multi-DRM contents easily.

To be completed.

Shaka Packager can talk to PlayReady Key Server that implements

fetch encryption keys.

=======
|

Using Raw Key
|
||||
=============
|
||||
|
||||
*Packager* allows encrypting contents with raw key.
|
||||
Shaka Packager supports raw keys, for which keys and key_ids are provided to
|
||||
Shaka Packager directly.
|
||||
|
||||
This is often used if you are managing the encryption keys yourself. It also
|
||||
allows you to support multi-DRM by providing custom PSSHs.

Widevine
|
||||
========
|
||||
Using Widevine Key Server
|
||||
=========================
|
||||
|
||||
There are two options to package a Widevine DRM encrypted content:
|
||||
The easiest way to generate Widevine protected content is to use Widevine Cloud
|
||||
Service.
|
||||
|
||||
1. If you know the encryption keys and have the associated Widevine PSSH at
|
||||
hand, you can provide them in clear text to *packager* directly. Refer to
|
||||
:doc:`/tutorials/raw_key` for details.
|
||||
|
||||
2. Provide *key_server_url* and associated credentials to *packager*.
|
||||
*Packager* will fetch encryption keys from Widevine key server.
|
||||
Shaka Packager can talk to Widevine Cloud Service or any key server that
|
||||
implements `Common Encryption API for Widevine DRM <http://bit.ly/2vTG4oo>`_ to
|
||||
fetch encryption keys.
|
||||
|
||||
Synopsis
|
||||
--------
|
||||
|

Widevine Common Encryption API supports request validation using either AES or

RSA.
