Now, now, let's be nice - Just hoping to exhibit the Perl virtue of laziness ;>

I'm already invoking jarsigner via qx{ ... } in my Perl scripts, it just happens to be agonizingly slow when I have to validate the signature on hundreds of Sun patch archive JAR files at a time - what with cranking up the Java interpreter for every invocation. Was simply asking if someone had already gone to the trouble of converting the algorithm to Perl or not. A couple of days will tell...

If not, then I won't be wasting my time when I attempt to do it using the modules that are available on CPAN as building blocks.
