The new release of Tighten Pro 1.0.11 is now available on the Mac App Store. This release includes a total rewrite of the Mac App Store receipt validation code generator including extensive checking of the security trust/certificate chain and new code to parse and validate in-app purchase receipts. The in-app purchase receipt validation code is 100% inline-able and as such can be used throughout your application code (ie. salted). Other new features include security code generation for DeveloperID/Gatekeeper applications and more. Tighten Pro represents a comprehensive solution for application developers dealing with the complexities of deploying to the Mac App Store and protecting their work from piracy.
