Hello!
Please, if we have
A1=h;
ascii(DEC)=72;
B1=G;
ASCII(dec)=103;
R1=/;
ASCII(dec)=47
and
A2=U;
ASCII=117;
B2=E;
ASCII(dec)=101;
R2=DLE;
ASCII(DEC)=16;
if R1= result of the operation A[1[ XOR B2
R2= result of the operation A2 XOR B2
WHAT IS then the operation XOR and what is it doing?
many thanks!
