title: android crypto implementation android 4.3
body: <p>I am referring "<a href="http://source.android.com/devices/tech/encryption/android_crypto_implementation.html#booting-an-encrypted-system" rel="nofollow">Android crypto implementation</a>" document. w.r.t Android 4.3 source.</p>
  
  <p>In point 2 it says <code>The framework starts up, and sees that vold.decrypt is set to "1"</code> </p>
  
  <p>But I am not able to locate the code that does things mentioned in point 2. Is anybody able to locate it? Is it somewhere related to class BackupRestoreConfirmation?</p>
