Questions tagged [signed-applet]

A privileged applet signed by the digital certificate. Privileged applets do not have the security restrictions that are imposed on sandbox applets and can run outside the security sandbox.

Java applets are loaded on a client when the user visits a page containing an applet. The security model behind Java applets has been designed with the goal of protecting the user from malicious applets.

Applets are either sandbox applets or privileged applets. Sandbox applets are run in a security sandbox that allows only a set of safe operations. Privileged applets can run outside the security sandbox and have extensive capabilities to access the client.

Applets that are not signed are restricted to the security sandbox, and run only if the user accepts the applet. Applets that are signed by a certificate from a recognized certificate authority can either run only in the sandbox, or can request permission to run outside the sandbox. In either case, the user must accept the applet's security certificate, otherwise the applet is blocked from running.
