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). WebThe cryptographic key that the sending party uses to encipher the data must be available to the receiving party to decipher the data.
