Sorry for my ignorance, but how do you get to decrypt the code to run?
Use any kind of wrapper? Is such a wrapper written in C? Do you store
the key inside such a wrapper? 

The same problem would happen with AES or any other crypt method:
where and how to store the key in a way that's easy for the user. 


See you,
