crycall | Compile-Time Calls Obfuscator for C++14+

Description

This repository provides a compile-time calls obfuscator based on lambdas, virtual calls and on how std::function works.
Users can easily obfuscate their calls using the crycall and crycall_virtual macro provided in the header.
The repository includes an example demonstrating the usage of crycall.
Needs optimization off (C/C++ -> Optimization -> "Optimization" and "Whole Program Optimization")

Key Aspects

The actual sub that's being called is hidden.
All the arguments passed in the call are hidden.
Memory is correctly managed, everything gets free'ed after usage.
Supports virtual functions (see crycall_virtual macro)
Works well with crystr (see the repo)
Supports C++14 and higher versions.

Repository Structure

include/: Contains the crycall.hpp header file providing the compile-time calls obfuscation mechanism.
src/: Holds the example main.cpp file showcasing the usage of the crycall macro.
LICENSE: Licensing information for the provided code.
README.md: Documentation explaining how to use the crycall macro and example usage.

Usage

crycall(returntype, function, args...)

crycall_virtual(returntype, class_address, virtual_index, args...)

Note that the virtual_index must be the index and not the virtual offset. (index = offset / 0x8)

Usage Example

The repository includes an example demonstrating the usage of the crycall macro:

`main.cpp`

#include <iostream>
#include "crycall.hpp"

int sum(int a, int b)
{
    return a + b;
}

int main()
{
    printf("sum: %d", crycall(int, sum, 10, 5));

    return 0;
}
