This repository contains Snaps, a Flatpak, Windows packages, and a Docker Image.

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 containerised way.

Ubuntu Snap Packages

  • John the ripper, a password auditing software: check John the Ripper for more details. See the Installation notes.
  • IRPF, a Brazilian government tool: check this text for more details.
  • Namebench, a benchmark tool: check namebench for more details.
  • B1, a file archiver: check B1 for more details.

All the Snap packages are built using a build server. At this moment, I'm using Launchpad to build the Snap packages.

Anyone can get, for free (as in beer), the reviewed packages from uAppExplorer. Despite the fact it is an unofficial repository, all packages are hosted and reviewed (automatically) by Ubuntu.

Flatpak Package

  • John the Ripper also has a Flatpak package available. Click here for more details.

At this moment, I'm using FlatHub and GitLab to build the Flatpak package.

Windows Package

  • John the Ripper also has a Windows package available. Click here for more details.

At this moment, I'm using AppVeyor CI to build the Windows package.

Docker Image

  • John the Ripper also has a Docker image. Click here for more details.

At this moment, I'm using Travis CI to build the Docker image.


Using multiple providers, I've created my DevOps infrastructure. I am mostly interested in quality assurance, CI (continuous integration), and CD (continuous delivery). To achieve this goal, my testing scheme builds and inspects the source code of John the Ripper using:

  • Microsoft Windows:
    • Windows Server 2012 R2 Datacenter (6.3.9600 N/A Build 9600);
    • Windows Server 2016 Datacenter (10.0.14393 N/A Build 14393);
    • Windows Server 2019 Datacenter (10.0.17763 N/A Build 17763);
  • Unix®-like BSD:
    • FreeBSD 11 (11.2-RELEASE);
    • FreeBSD 12 (12.0-RELEASE);
  • MacOS:
    • macOS 10.13 (Darwin Kernel Version 17.4.0);
    • macOS 10.14 (Darwin Kernel Version 18.5.0);
  • Linux:
    • CentOS 6, Ubuntu 12.04, Ubuntu 16.04, Ubuntu 18.04, Ubuntu 19.04, Ubuntu 19.10 (devel), and Fedora 30;
  • Compilers:
    • gcc 4.4, gcc 4.6, gcc 4.8, gcc 5.4, gcc 7.2, gcc 7.4, gcc 8.3, and gcc 9.0;
    • clang 3.9, clang 4.0, clang 5.0, clang 6.0, clang 7.0, and clang 8.0;
    • Xcode 9.4; Apple LLVM version 9.1.0 (clang-902.0.39.2);
    • Xcode 10.2; Apple LLVM version 10.0.1 (clang-1001.0.46.4);
  • Builds:
    • SIMD and non-SIMD builds;
    • OpenMP and non-OpenMP builds;
    • LE (Little Endian) and BE (Big Endian) builds;
    • ASAN (address sanitizer) and UBSAN (undefined behavior sanitizer);
    • Fuzzing (;
    • MinGW and Wine on Fedora Linux;
    • CygWin on Windows Server;
    • OpenCL on CPU using Apple, Intel, and POCL ( runtimes;
    • OpenCL on GPU using Azure cloud (work in progress);
    • And a final assessment using ARMv7 (armhf), ARMv8 (aarch64), PowerPC64 Little-Endian, and IBM System z.

Plans and future vision:

  • Develop a fully automated build and release pipeline using Azure DevOps Services to create the CI/CD pipeline and Azure Services for deploying to development/staging and production. See the release workflow here.

Please inspect all packages prior to running any of them to ensure safety. We already know they're safe, but you should verify the security and contents of any binary from the internet you are not familiar with.

We take security very seriously.
