John the Ripper is a password cracking and hacking tool or software which is completely available as a free download and developed for the Unix Operating System (OS). But now it can run on a different platform (approximately 15 different platforms). These platforms are as follows: Unix, DOS, Windows, and Win32, etc. On our website, you can find a great variety of video game mods files. You will be surprised by the vast selection – we offer you Farming Simulator 15, Farming Simulator 17, American Truck Simulator, Euro Truck Simulator 2, GTA5, Fallout 4 and other games mods.

John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix systems, supported out of the box are Windows LM hashes, plus lots of other hashes.

Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix systems, supported out of the box are Windows LM hashes, plus lots of other hashes and ciphers in the community-enhanced version.

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:

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.

Top contributors who made 10+ commits each since 1.8.0-jumbo-1:

• magnum (2623)
• JimF (1545)
• Dhiru Kholia (532)
• Claudio Andre (318)
• Sayantan Datta (266)
• Frank Dittrich (248)
• Zhang Lei (108)
• Kai Zhao (84)
• Solar (75)
• Apingis (58)
• Fist0urs (30)
• Elena Ago (15)
• Aleksey Cherepanov (10)

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.)

Creating strong passwords seems like an easy task at first glance, but it may actually take more than one would expect. Since there are many programs especially created to break such locks, it’s probably a good idea to actually test the strength of a passcode before using it.

A tool that is quite useful for this purpose is John the Ripper, a command-line utility that will also show its worth in case you need to recover a lost passkey. Since it doesn’t have a GUI of its own, you will have to open a Command window and run it from there to view the parameters which can be used to carry out the process.

The actual usage procedure is quite easy and you will have to follow a simple syntax which starts with the executable of John the Ripper, followed by the desired options and then by the password files.

There are several modes in which this application can work, starting with the ‘single crack’ method, followed by the wordlist and ‘incremental’ ones. It is also possible to employ a so-called ‘external’ mode which acts like a word filter. When using John the Ripper for testing purposes, you can run the benchmarks for a specific time by providing manually the appropriate value.

A great thing about this tool is that you will be able to save sessions and restore them when necessary, using their corresponding parameters. The status of these sessions can even be printed and you also have the possibility to have the deciphered passwords displayed.

All things considered, John the Ripper could actually be one of the better choices whenever someone needs to recover a password or assess the strength of a new one without having to go through a whole series of configurations. Nonetheless, the lack of a proper interface and of more functions may certainly deter some users from utilizing it.
