How to recover a password hint from a drive encrypted with Disk Utility?
I encrypted a drive with Disk Utility on macOS and set a password hint. I saved the password in the keychain and my computer was stolen. Unfortunately, my most recent backup is inside this encrypted drive. The answers on this Ask Different thread did not work for me. I use different passwords every time and rely on the hints to remember them.
Here is the ouptut of diskutil coreStorage list:
$diskutil coreStorage list

Note that at the bottom it says Content Hint: Apple_HFS. Note also that a bash command such as diskutil coreStorage unlockVolume [GUID] -passphrase [pass] takes 1-2 seconds to run and does not try to decrypt 240 GB, so I guess that the password is stored somewhere in this hierarchy.
If I knew the password hint, I would remember the password. How can I recover the password hint?

Two reasons: the question would be duplicate on Ask Different and I am looking for a software solution, since Apple products may not work.

You want to write your own program to recover the password hint?

Yes, I wonder if such a program exists.
