Yeah, I see that jsch needs KeyPairGenerator and KeyFactory  
implementations for DH. Both of these are simple to implement,  
though, and I'll post a patch for these this weekend.

There are probably a few other minor KeyFactory implementations that  
most code will expect, but aren't implemented yet in Classpath. All  
of these are fairly trivial, they just translate transparent keys  
(type KeySpec) to and from opaque keys (type Key). Grepping jsch for  
'KeyFactory.getInstance' might be instructive on what's missing.
