Foil 79 Signing Code with Sun's JDK 1.1.x

From Remarks on Internet and Java Security Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Mehmet Sen
Sun has its own set of signing tools, which have evolved along with the JDK.
The JDK ships with a command-line tool called javakey. "javakey" provides management of a database of entities (people, companies, etc.) and their public/private keys and certificates.
HotJava and the appletviewer program that comes with the JDK can validate JARs signed by javakey. Since the VMs in Communicator and Internet Explorer do not support javakey signing, in order to run javakey-signed applets with those browsers, users must download and install Sun's Java Plug-In.
