Before Continue, Check the Parameter first that might be useful later. Example of Binary: 01000110 01110010 01100001 01111001 Now let we try to translate the first byte 01000110, in binary there is quick way to calculate the results.
Values: 64, 32 ,16, 8, 4, 2, 1
in alphabets, calculate from behind. we only calculate bit that has true variable or I mean 1 (one). in last bit there zero then one, one, and zero, etc. we count from behind to front.
after see the table, we sum the Valued based the Parameter, 2 + 4 = 6, then it’s the sixth character.
so we know from that tables if the sixth char is F, we know the key then we still have to know if it’s uppercase or lowercase. it’s has 010 on first 3 bits contained there, so we can quickly know if the bytes telling us about uppercase F. let me do the other bytes so we can quickly go to next part, 18 for second bytes, 1 for the third, and 25 for the last one. the last 3 bytes is lowercase so after we find all character it means you may read your first binary bytes manually. by the way it’s Fray from the bytes you saw earlier.
