In the world, where Internet dangers are lurking everywhere, from malicious programs to insecurity of suring through the Internet, implementing security was of the utmost importance. Theoretical part of this paper shortly describes main tools and technologies which were used while developing the application, it also describes architectural concept and general direction in which development of the application was going. Practical part is dedicated to displaying different ways of implementations through development, with clarifications why and in what way was that exact implementation used compared to others. In spite of application being fully functional, nowadays, standards and user needs are growing uncontrollably, it could be said that this application is in very early stages of its lifecycle.
