Context Given two hex encoded strings of similar length we have to return xor of it. XOR (or, Exclusive OR) is a binary operation (like AND, OR) on bits. XOR gives true/1 as when the two inputs differ, otherwise false/0:

WebCrypto Challenge Set 2. This is the first of several sets on block cipher cryptography. This is bread-and-butter crypto, the kind you'll see implemented in most web software that does crypto. This set is relatively easy. People that clear set 1 tend to clear set 2 somewhat quickly. Three of the challenges in this set are extremely valuable in ... WebDec 23, 2024 · Now we need to get the XOR combinations of these bytes. To do that, we need to know what that means! XOR is a bitwise operator (used to compare two bits) that returns 1 if one bit is 1 and the other is 0, otherwise it returns 0. If we break down all the combinations it looks like this: Input A Input B Result. 0 0 0. dunleath porchfest
