Thanks to everyone for their help. I think I will try using symmetric encryption.
Two new questions: 1. Is there code available that implements a new type of filesystem directory? 2. Does anyone have any suggestions or warnings? I.e. if Lucene opens all the files in a directory and then randomly accesses them, I might have memory problems with large indexes. Thanks for any help.

If the ability to block reverse engineering is critical, you should use PKI and would result more and more performance loss than those symmectic methods.
