Free ParaChat Basic & BasicPlus Get Signed Java Applet


The free ParaChat Basic & ParaChat BasicPlus log-in panel now includes a "Java (Signed)" client selector:

 
When an end-user chooses the "Java (Signed)" client option, they will be connected to ParaChat via a signed Java applet.  During their initial connection attempt, they will see a dialog that requests permission to run the applet: 



To allow the signed Java chat applet to load, click the Run button.  So the dialog does not display during subsequent visits, check the "Do not show this again for apps from this publisher and location above" check box.

The signed ParaChat Java applet has a signature that a web browser may verify through a remotely running, independent certificate authority server. Producing this signature involves specialized tools and interaction with the certificate authority server maintainers themselves. Once the signature is verified by the certificate authority server, and the end-user also approves, a signed Java applet can get more rights, becoming equivalent to an ordinary standalone program. This approach allows Java applets to be used for many tasks that are otherwise not possible by client-side scripting. However, this approach requires more responsibility from the end-user because they have to decide whom they trust.
