In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: A 0 = A, A A = 0, A B = B A, (A B) C = A (B C), (B A) A = B 0 = B, For example where denotes the exclusive disjunction (XOR) operation. This operation is sometimes called modulus 2 addition (or subtraction, which is identical).

WebWhile in boolean algebra XOR is an eXclusive OR logic operation, in arithmetic context it's just an addition modulo 2. So to answer the original question: in modern cryptography XOR means addition , and addition is used every time we need to combine two blocks of binary data (which in many ciphers happens quite often).
