A development of a configurable system for handling X509 certificates

The X509 certification is one of the most important standards used today in a large number of different authentication mechanisms. As such, they represent one of the important topics at the Computer Security course at the School of Electrical Engineering, University of Belgrade. This paper describes a configurable system for handling X509 certificates, which has been used within the practical project at the Computer Security course. The system provides the ability to generate, sign, and manipulate X509 certificates. The system was implemented in such a way that the graphical user interface (GUI) is completely separated from the logic, which relaxes the students from GUI programming and enables them to concentrate on programming the part related to the certificates. The system has been successfully used at the course in the previous school year.
