Signed Applets



In Java 1.1, it is possible to attach a digital signature to a JAR file. When a Web browser or applet viewer loads a JAR file that has been signed by a trusted entity, the browser may grant the applet contained in the JAR file priviledges, such as the ability to read and write local files, that are not available to untrusted applets.
