Ask HN: How secure is the encryption offered by OS X's Disk Utility?

If you've ever used Microsoft Windows Encrypting File System (EFS), you'd know that it's pretty much useless. The file table is not encrypted, exposing valuable details about user activity.

Sure, you can't read the contents of a file, but you sure do know a lot about what someone's been up to, by booting up your own system, while mounting their disk as a read-only slave.

You will see highly informative file names, file sizes, and all dates denoting creation, last access, last change, and owner. In a work environment, this means your boss can see a file like:

  C:\Users\User\Documents\i_hate_my_boss_but_my_boss_has_a_daughter_too_hot_to_give_up.txt (12KB, 2017-06-17 13:04:47)

Whoops! Forgot to delete that one!

interesting:

  1) your name is 'User'
  2) you actually do use underscores instead of spaces
  3) any pics?

On a serious note: using archived/compressed files might be fine when one is aware about the shortcomings.
