TODO
* format support
  - handle volume offset detection of partial encrypted logical volume
  - use the VMK signature (a6 a6 a6 ...) to indicate the volume is unlocked not the unencrypted volume header?
  - volume with no 0x001a, 0x0305 and 0x0505 ?
  - remove libfvde_logical_volume_descriptor_get_last_block_number after debugging unsupported format variants?

* libfvde
  - libfvde_segment_descriptor_compare check for overlapping ranges
  - clean up: split off AES KEK functions
  - add handling of FVDE volumes with corrupt metadata, e.g. file header
  - store passwords as hashes?
  - read and compare secondary (physical) volume header
  - support out-of-order physical volume file IO pool

* add debug output
  - encryption method
  - checksum algorithm

* pyfvde
  - add functionality to set encrypted context plist from a file-like object

* fvdeinfo
  - print logical volume name and/or identifier when asking for a password

* fvdemount
  - print logical volume name and/or identifier when asking for a password

* code clean up
  - remove deprecated functions from libfvde and pyfvde
  - remove libfvde_volume_get_logical_volume_encryption_method
  - rename FileVault to CoreStorage ?
  - check for leading spaces
  - check for () without spaces
  - check for = alignment
  - check for if ( instead of if(
  - check error codes

* check README files
  - make sure pkg-config is mentioned as a dependency
