PE-Packer
 

PE-Packer is a simple packer for Windows PE files. The new PE file after packing can obstruct the process of reverse engineering.

Warning
This project is just a demo for beginners to study Windows PE Format and Assembly Language. It still has some compatibility problems and bugs that cannot be used in practice.

How it works:
It will do the following things when packing a PE file:

• Transforming the original import table.
• Encrypting sections.
• Clearing section names.
• Installing the shell-entry.

When running a packed PE file, the shell-entry will decrypt and load the original program as follows:

• Decrypting sections.
• Initializing the original import table.
• Relocation.
