    Subject: Question about JDK 1.2 security packages

Hello,

My question is will the JDK 1.2 security packages allow mere mortals
such as myself to read signed objects into my applications and to verify
the signatures. This is not clear to me. I think I need a tutorial on
how to achieve this.

I have looked at how appletviewer (jdk1.1.4) does this and a whole bunch
of non-core classes are apparently required, which I do not care to
implement myself. The crucial class appears to be
sun.tools.jar.JarVerifierStream in JDK1.1.4, but I cannot see an
equivalent in the core classes of JDK1.2.
