I have a strange problem, I have encrypted my cc # using Rails - works  
great, now I need to use that private key to decrypt the # using Visual  
Basic - not working so great. Apparently VB has little or no  
functionality to decrypt something by giving it a private key, unless  
you do it a very weird way, which I am having trouble with. Is there a  
way to get at the modulus and the xponent of the key so I can write it  
as an xml file so VB will be happy? Thanks,
