I built a Windows PE packer in C with manual loading, compression / encryption, and TLS/SEH support

I've recently published a custom executable packer for Windows `.exe` files made in C, called AlushPacker. It first encrypts and compresses the entire input executable, then, the unpacking routine does the reverse operations and then begins to manual map itself, all within the same process. Essentially it reliably replicates the Windows loader and "becomes" a different executable that is stored encoded in a C buffer.

Right now the project has to be compiled from source to pack the file you want, because the builder is still in progress. But I've attached a few sample files in case you want to see how it works.

This took me a lot of time and research to make. I spent a lot of time mainly by debugging and reverse engineering internal Windows structures and logic. I think I've come pretty far, and that you would be interested in this project.

Let me know what you think! :)
