(It was encrypted on OS X 10.6, with legacy filevault) I've seen John the Ripper mentioned a lot for cracking passwords, I've gotten as far as getting a build (1.7.9-jumbo-7 macosx-x86-64) installed. I have a word list ready and a vague idea of what my pass could be, I'm just not sure where to go from here.

Crack Mysql Password Hash John The Ripper Software. You'll learn how to use John the Ripper to recover passwords from. John the Ripper Pro is a free and open source password cracker tool for Mac computers. Its primary purpose is to detect weak Unix passwords, although Windows LM hashes and a number of other password hash types are supported as well. This app has a simple to use interface.
- John the Ripper is a fast password cracker, currently available for many flavors of Unix, macOS, Windows, DOS, BeOS, and OpenVMS (the latter requires a contributed patch). Its primary purpose is to detect weak Unix passwords.
- John the Ripper is a free password cracking software tool. Initially developed for the Unix operating system, it now runs on fifteen different platforms (eleven of which are architecture-specific versions of Unix, DOS, Win32, BeOS, and OpenVMS).
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.

John the Ripper is free and Open Source software, distributed primarily in source code form. If you would rather use a commercial product tailored for your specific operating system, please consider John the Ripper Pro, which is distributed primarily in the form of 'native' packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance.
What's New:
We've just released John the Ripper 1.9.0-jumbo-1, available from the usual place, here.
Only the source code tarball (and indeed repository link) is published right now. I expect to add some binary builds later (perhaps Win64).
It's been 4.5 years and 6000+ jumbo tree commits (not counting JtR core tree commits, nor merge commits) since we released 1.8.0-jumbo-1:
![John John](https://buer.haus/wp-content/uploads/montecrypto/image7.png)

During this time, we recommended most users to use bleeding-jumbo, our development tree, which worked reasonably well - yet we also see value
in making occasional releases. So here goes.

About 70 others have also directly contributed (with 1 to 6 commits each), see doc/CREDITS-jumbo and doc/CHANGES-jumbo (auto-generated from git). Many others have contributed indirectly (not through git).
Indeed, the number of commits doesn't accurately reflect the value of contributions, but the overall picture is clear. In fact, we have the exact same top 6 contributors (by commit count) that we did for the 1.7.9-jumbo-8 to 1.8.0-jumbo-1 period years ago. That's some stability in our developer community. And we also have many new and occasional contributors. That's quite some community life around the project.

Unlike for 1.8.0-jumbo-1, which we just released as-is without a detailed list of changes (unfortunately!), this time we went for the trouble to compile a fairly detailed list - albeit not going for per-format change detail, with few exceptions, as that would have taken forever to write (and for you to read!) This took us (mostly magnum and me, with substantial help from Claudio) a few days to compile, so we hope some of you find this useful. Included below is 1.9.0-jumbo-1/doc/NEWS, verbatim.

Major changes from 1.8.0-jumbo-1 (December 2014) to 1.9.0-jumbo-1 (May 2019):
- Updated to 1.9.0 core, which brought the following relevant major changes:
- Optimizations for faster handling of large password hash files (such as with tens or hundreds million hashes), including loading, cracking, and '--show'. These include avoidance of unnecessary parsing (some of which creeped into the loader in prior jumbo versions), use of larger hash tables, optional use of SSE prefetch instructions on groups of many hash table lookups instead of doing the lookups one by one, and data layout changes to improve locality of reference. [Solar; 2015-2017]
- Benchmark using all-different candidate passwords of length 7 by default (except for a few formats where the length is different - e.g., WPA's is 8 as that's the shortest valid), which resembles actual cracking and hashcat benchmarks closer. [Solar, magnum; 2019]
- Bitslice DES implementation supporting more SIMD instruction sets than before (in addition to our prior support of MMX through AVX and XOP on x86(-64), NEON on 32-bit ARM, and AltiVec on POWER):
- On x86(-64): AVX2, AVX-512 (including for second generation Xeon Phi), and MIC (for first generation Xeon Phi).
- On Aarch64: Advanced SIMD (ASIMD). [Solar, magnum; 2015-2019]
- Bitslice DES S-box expressions using AVX-512's 'ternary logic' (actually, 3-input LUT) instructions (the _mm512_ternarylogic_epi32() intrinsic). [DeepLearningJohnDoe, Roman Rusakov, Solar; 2015, 2019] (In jumbo, we now also use those expressions in OpenCL on NVIDIA Maxwell and above - in fact, that was their initial target, for which they were implemented in both JtR jumbo and hashcat earlier than the reuse of these expressions on AVX-512.)
