Which still sounds like your employer was simply incompetent because why was any type of perceptual hashing scheme even involved?
Signing digital data with hardware secure tokens is a commodity capability in the iPhone many of HNs users are reading this site with.

You’re probably right. This is easy, basic stuff that any recent college grad can do with their eyes closed.
I think this has been around for not so long

This was quite a while, before that.
Sure but conceptually no one should've been able to crack any hashing scheme anyone half-way decent at their job could come up. SHA256 is the default and it's unbroken. Even SHA1 has scant few known collisions. So like...what the heck were they hashing and how that anyone was able to crack it?
Maybe its more like the hash was a well known secure hash but someone managed to extract the salt/private key/signing certificate from the camera?
