Windows PE Packer
What it is
Windows PE Packer is a free, MIT-licensed command-line project for packing Windows PE files. Its process transforms the import table, encrypts sections, clears section names, and adds a shell-entry. When a packed file runs, that entry decrypts the sections, initializes the original import table, and performs relocation. The project describes these changes as a way to obstruct disassembly, searches for constant strings, and import-table analysis.
The command takes an input filename and an output filename: PE-Packer . It currently handles only 32-bit .exe programs and must be configured for 32-bit Windows. Building requires MASM32, MinGW-w64 with the i686 architecture, and CMake. The maker describes the project as a beginner demonstration for studying the Windows PE format and assembly, and says compatibility problems and bugs make it unsuitable for practical use. It is written in C and Intel x86 Assembly, and the repository lists no releases.
For and against
For
- Free and distributed under the MIT License
- Packs Windows PE files
- Command-line input and output filenames are documented
Against
- Processes only 32-bit .exe programs
- Requires a 32-bit Windows build setup
- Maker reports compatibility problems and bugs
- Repository lists no releases
The verdict
Windows PE Packer demonstrates several PE packing steps, but its maker says compatibility issues and bugs make it unsuitable for practical use. It is limited to 32-bit .exe files and requires specific build tools.
Who it suits
This project may suit beginners studying Windows PE format and assembly who can work with its 32-bit build requirements. Its maker says it is unsuitable for practical use.
