History
John "Juce" Bruce a7cded376e Skip padding for content keys differently 
(This is a merge of http://go/wvgerrit/151891.)

A previous patch changed how we skip padding when extracting keys from
key containers in license.cpp. Unfortunately, this broke generic
signing when an ODK core message is not in use:

1) "Content" keys for signing are 32 bytes long, but content keys were
   assumed to be 16 bytes long.
2) When an ODK core message IS in use, the result of the extraction in
   license.cpp is ignored.

The only way to know the correct length of a content key container in
License Protocol 2.1 is to leverage the knowledge that it will always be
padded by exactly 16 bytes. This will have to change if we ever
implement support for License Protocol 2.2, as all key containers are
unpadded in that version.

README 

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
