I appreciate the tips, but we have looked at using cryptix and have run 
into limitations, particularly as regards memory usage when encrypting 
large files and are now thinking that it would be better to use the 
native compiled gnupg code. So, for now, the question is whether it 
would be better to invoke the gpg executable directly or to use the 
gpgme shared library via JNI.

Thanks,
