First, generally speaking, encryption is the shell we often consider, an executable file, how to encrypt to be safe? The usual means is the Packers. The working principle of the Shell tool is to encrypt the code and data of the executable file as data storage.

After a long code, the code of the original executable file and the Data section restore, and then jump to the original entrance, continue to run.
