<p>Shaka Packager supports fetching encryption keys from Widevine Key Server and
PlayReady Key Server. Shaka Packager also supports Raw Keys, for which keys are
provided to Shaka Packager directly.</p>

<p>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.</p>
