All I found in KraClient is a KeyClient which role in retriving process is limited to returning some generic "Key" object. I would love some "find usages" that works across group of jars to find out where that recovering is.
In meantime I refactor PKCS12Export to get that working, but propably it could be done better. Now what is the problem, how to change the "Key" object to some object that implements org.mozzlila.PrivateKey ? I checked all this privatekey classes and any of this had a public constructor or builder with rawdata(byte) and mozilla jss documentation sucks.
