Client software for the exercises in Crypto 101, the introductory book on cryptography.

Project description

This is a client for the game-shaped exercises which are part of Crypto 101, the introductory book on cryptography by lvh.

Testing and documentation

The short version: use tox.

The long version: see the extra notes for merlyn.



Huge improvements to test suite. Also added support for creating credentials, so you can actually use stanczyk and only stanczyk without ever having to touch any internals yourself.


A much nicer version you can actually play around with.

  • stanczyk is now continuously tested, thanks to Travis CI. Coverage is measured thanks to Coveralls.
  • Solution notification: when an exercise is solved, stanczyk will say something.
  • Exercise listing and exercise details listing commands.
  • Proxy commands. You can now connect to remote virtual servers.
  • Nicer terminal line overwriting routines, which makes it less obvious that stuff is happening asynchronously (sometimes).
  • When starting, a nice table is displayed with all of the available commands, plus a short description of what they do.

I’ve made a short video that roughly coincides with this version.


Initial version. Contains a nice basic manhole with no extra commands.

Name and spelling

stanczyk is named after Stańczyk, a historical Polish jester. Other Crypto 101 projects (such as merlyn, arthur and clarent) were already named after things from the court of Arthurian legend; I picked Stańczyk because:

  1. Poland is awesome.
  2. This project looks simple, but it’s actually pretty clever; perhaps more than its peers.
  3. Poland is awesome.

The banner is an excerpt from the famous painting of Stańczyk by Jan Matejko.
