Different signatures for passbook files

Question

I am using jpasskit to generate and sign passes. So, I created a signature file from a sample manifest.json, using my p12 file and the Apple WWDRCA certificate. Then I decided to do the same thing (using the same manifest and certificates) using this Objective C code. But the signature files are different from each other.

I suspect there is something wrong with the jpasskit code. So, is there any way to decrypt the signature or otherwise inspect them somehow to see what is wrong?

Answer 1

Looking at your pass signature (provide in chat), it looks like you are using an Apple Production IOS Push Services certificate (com.paguemob.mobileios.PagueMob) to sign your pass.

You need to be signing with a Pass Type ID certificate, and that certificate must match the name of the certificate you have in your pass.json (pass.com.paguemob.mobileios.PagueMobS).
