Cryptris

A game about asymetric cryptography

Cryptris is a game designed to help people in getting a grasp about how cryptography works, by playing an arguably tetris-like game.

The game was developped by Digital Cuisine for Inria and is based on a concept created by Léo Ducas.

Technology

This game uses html, css and javascript. No server were harmed during the development process.

Installation

The whole application is designed to be a serverless application, hence the installation is pretty straightforward: simply clone this repository or download it as an archive.

Launching the game

To launch the game, simply open the index.html file in a compatible web browser.

Configuring the game for using on a custom domain / url

Changin the app's url is just a matter of changing the url that social networks will use to fetch data about Cryptris (title, descriptions, picture previews…). Unfortunately, due to the serverless nature of this project, a few occurences of this url had to be hard-coded in the html files' meta tags. A global configuration variable is used everywhere else where the app's url is needed, this variable can be found in the js/cryptris-settings.js file.

Before publishing the game, make sure that you proceed to the following:

• open up js/cryptris-settings.js.
• look for the line where cryptrisSettings.appUrl is defined.
• copy appUrl's actual value (e.g. http://inriamecsci.github.io/cryptris)
• search and replace this url in the game's .html files.
• set cryptrisSettings.appUrl to whatever your new url is.
• upload to your new url and carefully test that every sharing function still works as expected.

Be sure to update the app settings for facebook (facebook apps) and google+ (google API console), as of may 2014, twitter doesn't ask for this.

Hosting the game on github

To publish on github the only thing you need to do is to make sure that your gh-pages branch is up-to-date and push it to your github account. You should be able to access it via http://[username].github.io/cryptris where [username] should be replaced by your actual github username.
