When run against a file in this format John The Ripper does a pretty good job at identifying the hash type and beginning to try and break it. John the Ripper Wordlist Crack Mode. In this mode John the ripper uses a wordlist that can also be called a Dictionary and it compares the hashes of the words present in the Dictionary with the password hash. We can use any desired wordlist. John also comes in build with a password.lst which contains most of the common passwords. Now we need to combine these two files into one.

The input format is a printable hash, which can either be directly created with john's tool “wpapcap2john” (ships with jumbo) from a packet capture in pcap format as produced by tcpdump, wireshark or airodump-ng; or by doing an intermediate conversion to Hashcat's hccap format as described below.

You can convert airodump's .cap file to .hccap in one of the following ways:
When you have hccap file you need to convert it to john's input format using “hccap2john” program shipped with recent jumbo versions.It encodes hccap file to “$WPAPSK$essid#b64encoded hccap”
Example testcase you can get from http://wiki.wireshark.org/SampleCaptures?action=AttachFile&do=view&target=wpa-Induction.pcap or wpa-Induction.tar.gz
From that point you can use john as you always do. The format comes in two flavours:
- -format=wpapsk (will use CPUs, is SIMD and OpenMP capable)
- -format=wpapsk-opencl (for any OpenCL GPU or CPUs)

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.
