In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: A ⊕ {\displaystyle \oplus } 0 = A, A ⊕ {\displaystyle \oplus } A = 0, A ⊕ {\displaystyle \oplus } B = B ⊕ {\displaystyle \oplus } A, ⊕ {\displaystyle \oplus } C = A ⊕ {\displaystyle \oplus }, ⊕ {\displaystyle \oplus } A = B ⊕ {\displaystyle \oplus } 0 = B,For example where ⊕ {\displaystyle \oplus } denotes the exclusive disjunction operation.
