Android White Paper
encryption key must not be written to storage
if active-encryption key must be AES-encrypted with lock screen passcode
using a slow stretching algorithm
user has not specified a lock screen passcode/has disable passcode
the systems use a default passcode to wrap the encryption key
device provides a hardware-backed keystore, the password stretching algorithm must be cryptographically bound to that keystore
