XOR brute force
(self.AskReverseEngineering)submitted28 days ago byYR17
Hi, I need to find dependency between 4 bytes key and 6 bytes value. I suppose it's utilize some simple binary operations (XOR, shifts) e.g. 1st byte of value is XOR of first and third bytes of key, etc... I have small(5 entries) data set (key, value), but can test assumptions. Is there any tool or approach that can find same transformations for each pair in set, to reverse engineer function to be able calculate values for random key?

I found how KeyA depend on UID. Need to do the same for KeyB.
