For example, say a DMG file isn't just storing compressed files like images and videos but is instead holding a software program. You can extract/open the DMG file in Windows using one of the programs mentioned below, but you can't actually execute the program and use it like you would another Windows application. To use the same program in. Learn how to open or convert files with.DMG extension. Read the informations and fix.DMG files errors.

John The Ripper : Cracking a .DMG
Let's cut to the chase right now:
Cracking encrypted disk image, AKA DMG is feasible, but, and there are many buts, is extremely, extremely time consuming.
If you do not remember at all the password, or if you attempt to crack in 'blind mode', you will probably need to teach your kids how to do it: By the time you'll have a fighting chance, you'll be long dead.
Step 1: Write down everything you can remember about the forgotten password, i.e what you could have used, and what you are sure not to have used, i.e. never used a space or a '@' sign.

Step 1a: If you remember enough of your password, or if you are just missing trailing numbers i.e Mypassword???? >> MyPassword1234 and do not remember if it's 1234 or 4321, or 9999, Just use CrowbarDMG and a Wordlist.
For good Wordlists, go here!
If you need to create a specific wordlist (because you remember what you may have used and, most importantly, what you may have not used, go here and look for Wordlists On Demand)
Warning!: CrowbarDMG is slow!
CrowbarDMG is basically a GUI for the hdiutil command

ETA for trying 9999 passwords: About 3 hrs
99,999 passwords: About 30 hrs
999,999 passwords: About 300 hrs Or 12 days ....
Step 2: Do you know how to compile and use John The Ripper? I mean 'use it! including editing Rules, etc?

--> No? Proceed here. Read carefully. Pause. Repeat.

--> Yes! Ok, Sure?

1) Download JTR, version Bleeding Jumbo by Magnum
As of Aug 2013, it's here otherwise here

2) Compile. Don't forget to edit the Makefile and John.conf. Check for CUDA and OMP/MPI RUN. Creating a new Charset? that could be wise...

3) Run dmg2John.py to extract the hash
python [path to file ]dmg2john.py [path to file] myfile.dmg > dmg.txt

4) Edit/Create your rules as needed

5) ./ John etc (Run Baby, run ....)

6) There is always Hashcat (Win/Lin)

7) Because most you have seen, in movies, Hackers cracking an AES within minutes, you'll try without thinking too much about it.
It's going to leave you with a lot of time to read ....
Enjoy ...
8) Without going into too much details, the use of GPU assisted is highly recommended. If you have one of those ones, you'll most likely increase your speed by a factor of 1000, sometimes 10,000 times faster.
