Unless I'm mistaken, I believe the point of disk encryption is to deny
access to the data. For example, I typically only encrypt data volumes
and swap, since there is less point in encrypting executables -
especially since they should be mounted ro.

The method you're seeing *is* the method for the rightful owner to
recover their data.
