Scripting Crypto via XPCOM

[Jean-Marc Desperrier]

In the "Scripting Certs via XPCOM" thread, Rodrigue gave a method that 
enables to call a XPCOM component from javascript to get back a cert 
nickname.

But it seems you can not do much anything useful once you get that ? 
None of the other NSS Api function that would enable to access the 
private key, and do cryptographic operation is accessible from XPCOM, 
are they ?

Rodrigue, if you read this, did you succeed in doing anything 
interesting in XPCOM with this, or are you in fact only using JSS ?

Also it seems that if I had a java applet that would be able to do the 
crypto through other ways, there is no easy way to do java->javascript 
communication to call this code.
