This is to be expected --- raw binary executables are generally very  
redundant, and thus compress well.  Encryption seeks to dramatically  
increase data entropy.  Since data compressibility is inversely  
proportional to data entropy, binary encrypted data doesn't compress  
as well.

If only Apple's IPA bundles could compress executables *then* encrypt  
them, we wouldn't have quite as much of a problem.  :^>
