The title is not too particular, so to specify extra verbosely: how does iOS be sure that the app’s signature matches the contents inside the payload?
I am at present making an attempt to barely modify the information inside an iOS recreation. I’ve the ipa put in, then I view the information by altering the .ipa extension to .zip. From there, I can view the entire non-compiled information for the app. To change, I extract the info. A considerable amount of the info this app makes use of comes from xml. I discover a particular xml file that pertains to what I want, I modify it, then I zip up the extracted information right into a folder with the very same identify, confirm the format is equivalent to the unique .zip, then change the extension again to .ipa.
Nevertheless, when doing this, the appliance I’m utilizing to put in signed and verified IPAs notes there was a change. It can not detect a change after I merely change the extenstion to .zip, then change it again to .ipa.
I am questioning, what a part of what I did is detectable as not matching the signature?
