Assume:
unsigned char A = 10;
unsigned char B = 11;
unsigned char C = 12;
unsigned char Diff1 = A ^ B;
unsigned char Diff2 = B ^ C;
//find any of A or B or C using Diff1 and Diff2
Question is: There were 3 values initially for which we found 2 differences. Is there any way we can find any if A or B or C using 2 differences Diff1 and Diff2?
I know XOR is not reversible unless you know the key, but keeping in view that unsigned __int8 is 0...255 maximum 256 different values.
stay well.
