anticheat.c ⚡

Lightweight performant anti-cheat written in C.

File verification tool which performs over 62% faster than standard file verification protocol.

Benchmarks

Standard File DFS and Hash time Benchmark (non-threaded-impl branch):

anticheat.c threaded DFS and Hash time benchmark:

Summary:

62%+ increase in performance for large file systems

Usage

1. To generate expected hashes (first time setup)

anticheat-dev <game_directory> -g

Remember to drag in verification.txt file (generated by the tool) into your game directory, and ship with the verification.txt file

2. To verify files

anticheat-dev <game_directory> -v

Will exit with code:

0 - Verification Success

3 - Unsuccessful (Tampered files)

Build instructions

In project root run:

make

To build the tool.

Running Benchmarks

To run timing benchmarks (For Multithreaded version only): (Run command first time only, requires around 100mb of space)

./timeBenchmark -setup

(Simply generates the expected hashes, performance wasn't considered at this step, so no multithreading)

./timeBenchmark -g

(Now can time the verification step, which is threaded)

./timeBenchmark -v

Look at this Nehal guy 💀
