PEBLoader.h allows easy hiding of WinAPI imports via PEB walking technique. No more obvious API calls in your import table!

What is this?

PEBLoader.h is a single-header library that lets you dynamically resol API functions without having them appear in your executable's import table. Instead of directly linking to functions like LoadLibraryA or GetProcAddress, this library walks the Process En Block (PEB) to find loaded modules and their exported functions.

Why would you want this? Well, some security tools and reverse engineers look at import tables to understand what your program does. With PEBLoader.h, your import table stays clean while you still get full access to the Windows API.

How it works

The magic happens through PEB walking:

1. Find modules by hash - Instead of storing module names as strings, we use Adler-32 hashes
2. Parse export tables manually - We dig into PE headers to find function addresses
3. No direct imports - Your executable won't show obvious API dependencies

Here's what a typical workflow looks like:

Ad usage

Want to be extra sneaky? You can resol by hash too:

This way, your executable contains zero readable strings related to the APIs you're using.

Core Functions

CLoaderDynGetModuleByAdler32(uint32_t hash)

CLoaderDynGetProcAddressByAdler32(HMODULE hModule, uint32_t hash)

CLoaderAdler32(const char *data, size_t len)

Wrapper Functions

These work exactly like their Windows API counterparts, but use PEB walking internally:

Compiler Support

This library was originally designed for Tiny C Compiler (TCC) and has been extensively tested with it. While it might work with other compilers like GCC or MSVC, we haven't tested it on anything else, so your mileage may vary.

If you're using TCC, you're golden. For other compilers, you might need to tweak the inline assembly or structure definitions.

Building

Since it's a header-only library, just include it:
