Is there a way we can be notified when some… Continue reading Detect reverse engineering using debugger
I know it’s hard to find but I am still trying to find it.
I have one input and two outputs as "short" and "long" keys. I want to find which algo or encryption is being used.
The encryption remains static means no diffe… Continue reading I have input text and 2 output of encryption short and long key. How to find algo being used [duplicate]

Apple’s NeuralHash algorithm — the one it’s using for client-side scanning on the iPhone — has been reverse-engineered.
Turns out it was already in iOS 14.3, and someone noticed:
Early tests show that it can tolerate image resizing and compression, but not cropping or rotations.
We also have the first collision: two images that hash to the same value.
The next step is to generate innocuous images that NeuralHash classifies as prohibited content.
This was a bad idea from the start, and Apple never seemed to consider the adversarial context of the system as a whole, and not just the cryptography…
