Hi
Can someone help me. I still get these errors when I try to compile classes from book. Logs below:

KeyTransEnvelopedDataExample.class
xception in thread "main" org.bouncycastle.cms.CMSException: key inappropriate for algorithm.

This normally indicates the unrestricted jurisdiction policy files
haven't been installed. There's an example program you can use to
confirm this in the first chapter - try that first and see how you go.
