John Package Description. John the Ripper is designed to be both feature-rich and fast. It combines several cracking modes in one program and is fully configurable for your particular needs (you can even define a custom cracking mode using the built-in compiler supporting a subset of C). John The Ripper, AKA John/JTR is the extreme opposite of intuitive, and unless you are an UberGeek, you've probably missed out few subtleties. https://moviesrenew.weebly.com/blog/windows-81-pro-download-crack. Secondly, John The Ripper is a bit like a Muscle Car delivered from the factory with the 'Eco' settings enabled by default.

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.

EPAG: Empirical Poke-Around Graph
Markov Probabilities

Two weeks ago I was in the midst of a nightmare. I’d forgotten a password. Not just any password. THE password. Without this one password I was cryptographically locked out of thousands and gigabytes worth of files I care about. Highly sensitive and valuable files that include work documents, personal projects, photos, code snippets, notes, family stuff, etc. The password in question unlocks these files from the protection of locally stored AES-256 encrypted disk image. A location where an “email me a password reset link” is not an option. File backups? Of course! Encrypted the same way with the same password. Password paper backup? Nope. I’ll get to that. I somehow needed to “crack” this password. If not, the amount of epic self-pwnage would be too horrible to imagine.

Before sharing how I got myself into this predicament, it’s necessary to reveal some details about my personal computer security habits. More specifics than I’m normally comfortable sharing.

As my badge wall shows, I travel a lot, all around the world, and often with the same laptop. A MacBook Pro. My computer becoming lost, stolen, or imaged by border guards and other law enforcement officers is a constant concern. To protect against these potential physical attacks, OS X dutifully offers FileVault.

FileVault is a full disk encryption feature utilizing XTS-AES 128 crypto. Enabling FileVault means that even if someone has physical possession of my computer, or obtains a full copy of the hard drive, they’d be the proud new owner of a cutting-edge machine, but unable to get any useful data off of it. That is unless my admin password, which unlocks FileVault, is ridiculously simple, and it isn’t. By all practical means, “cracking” this password is impossible.

What is possible is law enforcement, or a robber, forcibly stopping me and “asking” for my admin password, a method capable of defeating FileVault’s full disk encryption. Realistically, while my brazilian jiu-jitsu black belt certainly helps in many situations, it can be utterly useless in other real-world encounters. I’ll of course resist giving up my admin password to the extent I’m able, but must assume I may have to “comply” at some point. If this should happen, ideally my data, other than email, should remain safe even after the adversary lands on my desktop.

Setting up this type of layered security fall-back plan is where we return to the conversation of encrypted disk images. On OS X, Disk Utility can be used to create encrypted disk images called DMGs. DMGs are self-contained portable files, of customizable size, that when mounted (i.e. double-clicked) display on the desktop like any other disk drive where files can be stored.

Upon creation of DMGs the level of encryption strength can be set, the highest being AES-256. If FileVault’s AES-128 crypto is already “impossible” to crack, AES-256 DMGs are exponentially more impossible. To ensure this, all you have to do is set a reasonable password. We’re talking even 6 characters or longer, some upper and lower case, and maybe toss in a digit and special character. DON’T SAVE THE PASSWORD IN YOUR KEYCHAIN. Doing so defeats the entire purpose of what we’re trying to accomplish, because the admin password unlocks the keychain.
