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 can generate receipt validation code in Objective-C and Swift languages.
- 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.

This release mainly brings some bug fixes:
- [ENGINE] Enable StoreKit testing (Refer to the website for more details.)
Please pay attention that the generated code targets OpenSSL 1.0 by default. If you need to target OpenSSL 1.1, you MUST pass a command line option. Refer to the website for more details.
Ratings and Reviews
Works well with Xcode 7
The application has not been updated for a long time, and the negative review below further increased my doubt whether I should buy this incredibly useful tool. But yesterday I did anyway, because I realized that that negative review is actually the result of a user error. And indeed it is. The tool works just fine on Xcode 7.1 on El Capitan. There’s no need to replace any imports at all. Just configure your project right regarding the include files.
I would have given it 5 stars if it had not been for the lack of updates. I obviously wouldn’t be too happy if, say, 4.0 comes out tomorrow, but then again I believe it would be wise for the developer to continue to add more obfuscation to the output, as well as finding a way to obfuscate the openssl source itself.
Starting with Xcode 7 Apple has removed openssl. This caused Receigen to stop working. You can get your project to build by replacing all 222 instances of #import <openssl/headername> with #import “header name” to use the supplied headers. The problem is that the resulting app won’t work. It will fail to correctly verify the valid receipt added by the App Store, exiting with error 173. The proceedure at the Receigen site for testing receipt validation also doesn’t work.
The developer doesn’t respond to E-mail requests for help.
Untill this is fixed Don’t buy this App. This is a shame because this was such a huge time saver for developers.
It’s still great!
I have been using Receigen for several years now across many apps. Despite the lack of updates, it’s still working just fine. I just completed a new app using auto-renewable subscriptions and was pleasantly surprised to find all the support I needed was there from the 2014 release and working fine with Xcode 8.3.2.
