In the context of the Open eCard Project, industrial as well as academic experts have decided to work together on providing an open source and cross platform implementation of the eCard-API-Framework (BSI-TR-03112), through which arbitrary applications can utilize authentication and signatures with arbitrary chip cards.
The artifacts of the project consist of modularized, and to some extent extensible, libraries as well as client implementations such as a Desktop application (richclient), an Android app and a Java Applet.
Detailed build instructions can be found in the INSTALL.md file bundled with this source package.
The simplified build instructions are as follows:
$ git clone git://github.com/ecsec/open-ecard.git
$ cd open-ecard
$ git submodule update --init
$ mvn clean install
In case you received a preassembled source bundle, the build instructions are as follows:
$ tar xaf open-ecard-${version}.tar.xz
$ cd open-ecard-$version
$ mvn clean install
