Receigen

Description

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 nicely integrates with Xcode for a streamlined build process.

Here are the key points:
- Receigen can generate receipt validation code for OS X and iOS platforms.
- Receigen features a fast and smart code generator; every time the code is generated, it is different in order to defeat binary pattern detection.
- The generated code allows to access all the receipt properties.
- The generated code is compatible with ARC (Automatic Reference Counting).
- The binary code produced is obfuscated by integrating various mechanisms like string and constant obfuscation, non-predictable branching, non-explicit function calls, dead-code, etc.
- Receigen can also be invoked on the command line so it integrates inside a Xcode build process.

Easiest way to handle this and reduce piracy

I thought receipt validation would be too complex, so I skipped it in v1.0 of my app. After seeing a bunch of piracy I bought Receigen and used it for our next release. So far, it hasn't been cracked. I waited to leave this review to ensure it didn't cause any issues, and so far after 2 updates, it's been great. Great app, and actually has saved us money (as our app uses a premium data provider that charges us). Thank you!

Time Saver

It worked for me, and saved me a ton of time. Receipt validation is not for the faint of heart but this app makes it so easy that I found it well worth the price.

Generated Code Outdated

It seems the generated code is outdated and causes compiler errors with the latest version of OpenSSL (1.1). I would love to give this app 5 stars, but I cannot. I sent the the developer a couple of e-mails, no response yet. If the app isn’t current, I’ll be seeking a refund because I do not want to embed an old version of OpenSSL in my app. I also don’t feel I should be editing generated code.

I hate leavng negative reviews. If the developer handles customer support properly, I will revise this review.
