AloPin

A tool for recovering (brute-forcing) the Family View PIN. This project was inspired by SPPRT, but I wanted to build my own version — so I guess you could call it PET

---

Requirements

• OS: Windows (Steamworks SDK is Windows-only)
• CMake: ≥ 3.20
• Compiler: MSVC (Visual Studio 2019/2022)
• Steamworks SDK: DAutomatically cloned as a submodule into external/SteamworksSDK
  • Requires 64-bit redistributables: redistributable_bin/win64/steam_api64.{dll,lib}

---

Building

1. Clone the repository and enter it:

   git clone --recurse-submodules https://github.com/rodeka/AloPin
   cd AloPin

2. Create and switch to a build directory:

   mkdir build && cd build

3. Configure with CMake:

   cmake .. -G "Visual Studio 17 2022" -A x64 -DBUILD_TESTING=OFF -DCMAKE_BUILD_TYPE=Release

4. Build:

   cmake --build . --config Release

   • Static libraries (crypto.lib, proto.lib) appear in build/lib/Release/.
   • The executable (alopin.exe) and DLLs are in build/bin/Release/.

---

Running

It is a requirement to have Steam running and be logged into the account.

cd build/bin/Release
./alopin.exe [options]

---

Testing

cd build
ctest --output-on-failure

Runs all unit tests if built with BUILD_TESTING=ON.
