Mac App Store Receipt Validation Code?

Question

Wondering if anyone has a tutorial or working code for the new Mac App Store\'s receipt validation? About the only references I\'ve been able to find so far are Apple\'s st

Answer 1

I reviewed Alan Quartermain's code and it looks good. Something to think about:

the last parameter here could/should be a compiled requirement stating that the code must be signed by YOUR certificate and no-one else's.

When the developer submits an app to the store for approval, the signing certificates are as follows:

3rd Party Mac Developer Application: me
Apple Worldwide Developer Relations Certification Authority
Apple Root CA

After the app is delivered from the App Store to the end user, the signing certificates are as follows:

Apple Mac OS Application Signing
Apple Worldwide Developer Relations Certification Authority
Apple Root CA

Also, I suggest only exit(173) when the receipt is missing, but everything else is in order.
