Receigen v1.8.0 MacOSX | 6 MB
Receigen is a smart code generator for App Store receipt validation (both receipt and InApp purchase).
The generated code is ready-to-integrate, pure C, fully debuggable and integrates various protection mechanisms to harden the reverse engineering. It also integrates nicely with Xcode for a streamlined build process.
