John the Ripper Packages

Openwall's John the Ripper (JtR) is a fast password cracker, currently available for many flavors of Unix and for Windows. 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, various macOS password hashes, as well as many non-hashes such as SSH private keys, encrypted filesystems such as macOS .dmg files and "sparse bundles", encrypted archives such as ZIP, RAR, and 7z, encrypted document files such as PDF and Microsoft Office's, plus lots of other hashes and ciphers.

Packaging and Application Distribution

Snap and Flatpak are cool new ways of distributing Linux applications among a wide range of different distros. They are technologies to deploy applications in a secure, sandboxed and containerized way.

A Docker image is a read-only template used to execute code in a Docker container. An image is an immutable file that contains the binaries, configuration files, libraries, dependencies, tools, and other files needed for John the Ripper application to run.

When the Docker user runs an image, it becomes one instance (it becomes a container, in other words, a running instance of the application).

SLSA Provenance Traceability

Running a non-OpenMP build on Windows

In some situations a non-OpenMP build may be faster. You can ask to fallback to a non-OpenMP build specifying the value of OMP_NUM_THREADS in the command-line. You avail the best SIMD instructions at one's disposal without any OpenMP stuff. E.g.:

 PS C:\john-the-ripper\run> set OMP_NUM_THREADS=1
 PS C:\john-the-ripper\run> .\john --list=build-info

Accessing OpenCL on Windows

If John the Ripper is not recognizing your GPU card:

make sure all required GPU drivers are installed;
restart your PC, if you have just installed the drivers.

📂 Snap

Delivered using Launchpad \ Supported architectures: amd64, arm64v8, ppc64le, riscv64, and s390x

A Snap is a gpg signed squashfs file containing an application together with its dependencies, and a description of how it should safely be run on your system.

You can install john by following the instructions at https://snapcraft.io/john-the-ripper. For distributions without snap pre-installed, users should enable snap support, then install:

 sudo snap install john-the-ripper

Just dance now:

 $ john-the-ripper -list=build-info
 [...]
 Build: linux-gnu 64-bit x86_64 AVX2 AC OMP OPENCL
 SIMD: AVX2, interleaving: MD4:3 MD5:3 SHA1:1 SHA256:1 SHA512:1
 Deploy: sandboxed as a Snap app
 [...]

You can also run the software using the official john alias:

 john -list=build-info

John runs confined under a restrictive security sandbox by default. Nevertheless, you can access and audit any file located in your home. Below, an usage example:

 john -list=format-tests | cut -f3 > ~/allTests.in
 john --format=SHA512crypt ~/allTests.in

For your convenience, the snap installed on your system contains the file /snap/john-the-ripper/current/snap/manifest.yaml which field build_url points to its build log.

The highlights (👀):

has fallback for CPU[*] and OMP;
has OpenCL available (GPU driver installation is needed);
John the Ripper is a "featured software" in the security category on Canonical Snap Store;
John the Ripper is a software with 4-star (⭐⭐⭐⭐) user reviews on Canonical Snap Store;
John the Ripper is tagged as safe, confined and auditable software on Canonical Snap Store;
John the Ripper supports and has a package for all architectures supported by Ubuntu itself.
also available via the alias john, e.g. john -list=build-info;
the latest released version:
- install from the Snapcraft stable channel.
a development version is also available:
- install from the Snapcraft edge channel.

[*] John the Ripper runs using the best SIMD instructions available on the host it's running on.

John the Ripper snap package has approximately eight thousand active users [*].

[*] 7 Day Active Users: the number of unique users who had at least one session within a 7 day period.

Enabling Aliases

You are free to pick and set up aliases. To enable the usage of aliases with John the Ripper snap, run sudo snap alias john-the-ripper <alias>. For example:

 sudo snap alias john-the-ripper john-snap
 sudo snap alias john-the-ripper.dmg2john dmg2john

Once enabled, John itself plus the *2john tools can be invoked using the aliases. In the example, to run John type john-snap.

| 📑 More examples of enabling alias for John The Ripper snap.

Running a non-OpenMP build

In some situations a non-OpenMP build may be faster. You can ask to fallback to a non-OpenMP build specifying OMP_NUM_THREADS=1 john <options> in the command-line. You avail the best SIMD instructions at one's disposal without any OpenMP stuff. E.g.:

 OMP_NUM_THREADS=1 john --list=build-info

Accessing OpenCL on Snap

As noted at https://forum.snapcraft.io/t/snaps-and-opencl/8509/17, the use of OpenCL by snaps is a problem. Support for NVIDIA cards is under development.

As a "general" solution (or in the case of AMD hardware), the user can run john out of the sandbox, unconfined (e.g., run /snap/john-the-ripper/current/bin/john).

Snap Deployments

If you followed the instructions above, you have installed the released version of john on your system. If you want to access the hot and bleeding development version of JtR, you must follow the edge channel. For a clean install:

 sudo snap install --channel=edge john-the-ripper

If you already have JtR installed:

 sudo snap refresh --channel=edge john-the-ripper

If you do so, you will be running the development version available on GitHub.

📂 Docker Image

Delivered using GitHub Actions \ Supported architectures: amd64 and arm64v8

Docker provides the ability to package and run an application in a loosely isolated environment called a container.

To use it:

 # CPU and GPU formats
 docker run -it ghcr.io/openwall/john:latest <binary id> <john options>

 # To run ztex formats
 docker run --device=/dev/ttyUSB0 ghcr.io/openwall/john:v1.9.0J1 ztex <john options>

Run John the Ripper and check if it is working:

 docker run ghcr.io/openwall/john # => uses the best SIMD available, tag 'latest' can be omitted
 docker run ghcr.io/openwall/john:bleeding # => uses the latest bleeding release
 docker run ghcr.io/openwall/john:latest best # => uses the best SIMD available

| 📑 More examples of running John The Ripper on Docker.

The highlights (👀):

OpenSSF SLSA 3 compliant;
has NVIDIA OpenCL available (GPU driver is required on the host);

Packages Checksums

Released packages checksums computed by Build Servers

File verification is the process of using an algorithm for verifying the integrity of a computer file. A popular approach is to store checksums (hashes) of files, also known as message digests, for later comparison. All john packages checksums (hashes) are computed by the CI servers.

By accessing the build logs for each release on GitHub releases you can view the hashes of all relevant files.

You can also go to https://github.com/openwall/john-packages/attestations for a list of our named artifacts along with their digest.
