I have left this tombstone entry for historical interest.
Java version 1.1 application for creating and managing digital signatures and signing Applets
so they can get past the security restrictions of the sandbox. This Javasoft standard for Applet-signing is only
honoured by Hotjava and Appletviewer, but not Netscape or IE (Internet Explorer), unless they use the Java Plug-In. Replaced by
keytool and jarsigner in Java version 1.2.
