Johnny the Awesome GUI for John the Ripper – Johnny Johnny Come Home !!!

Johnny is a GUI for John the Ripper. It was proposed by Shinnok. You could look onto original version on John the Ripper GUI sketches page.

Release 1

The first release is prepared to take more opinions from real users. This release includes all things from development release plus nice tabbed panel for mode selection and some additional clean-ups. Basic functionality is supposed to work: password could be loaded from file and cracked with different options.

What do you think? Your opinion is very welcome!

You could download and unpack tarball or use git:

  git clone -b release1

Then build and run (no installation required):

  cd johnny
  make && ./johnny

You could affect decisions about GSoC 2012. Please tell us your suggestions!

Development release

To review current state and make new decisions for GSoC 2012 here is cleaned up version (that has all not implemented features not available).

  1. Download tarball and unpack it,
    • Or clone using git,
  2. Enter directory,
  3. Build and run,
  4. Review and post your suggestions on john-dev list (subsribe here).
    • You are welcome!

For instance,

git clone -b gsoc2012review
cd johnny
qmake && make && ./johnny

Current state

Johnny is in development. Development was started as part of Summer of Security 2011 by Aleksey Cherepanov while Shinnok became a mentor for Aleksey.


At this moment there were no releases. So only source code is available through git:

git clone git://


Prebuilt binaries are available for testing.

Built from version of commit 6ae97db95fa989dca55aaef319a2839763aa018d x86_64-gnome x86_64-kde x86-gnome x86-kde (all was built on x86 and x86_64 (aka Amd64) Debian Squeeze (Stable) machines with KDE and GNOME respectively)


There are few screenshots here. They are done primarily to show differences from original version.

Aleksey Cherepanov propose to name screenshots as
johnny_<repo url with slashes replaced by underscores>_<git commmit name>.<format>
johnny_<repo url with slashes replaced by underscores>_<git commit name>_<screenshot number>.<format>
if there are more than one screenshot for certain commit.

So if someone wants to build exactly this version of Johnny he can do following:
git clone <repo url>
cd johnny
git checkout <git commit name>
