Android Full Disk Encryption

[docder]

https://source.android.com/devices/tech/...ation.html hasn't changed that I know of except Android 4.3+ now enables the allow_discards dm-crypt parameter, which issues the TRIM command to underlying flash storage. Great beta, will try it out on the master branch build. Most Android FDE passwords are simple because its tied to the screen unlock password (unless user has root/SU) and nobody wants to enter a high entropy pword multiple times per day.
