Seems possible. Pretty much every Android device has disk encryption disabled by default for performance reasons.

- russell_h 11y agoDisk encryption is required to be enabled by default on any device shipped with Android 6 (Marshmallow). There is an exemption for very slow phones, but I'd guess that most new medium or high end phones have it enabled now.
- mentat 11y agoWithout hardware keystore for the key encryption key it's sort of pointless as you can extract and brute force with any PBKDF2 round count that will be acceptable for a mobile user.
- bduerst 11y agoHasn't Android supported that since 2012? http://developer.android.com/about/versions/android-4.3.html#HardwareKeyChain http://developer.android.com/about/versions/android-4.3.html...
- mentat 11y agoI'm not sure if / how that's integrated into encrypted disk nor how prevalent having a TPM like chip is. TrustZone has had a lot of vulnerabilities.
- bduerst 11y agoThe majority of Android 6.0+ phones have disk encryption enabled by default. Previous android phones didn't have the hardware to handle the workload.
