WebSep 4, 2009 · XOR allows you to easily encrypt and decrypt a string, the other logic operations don't. If you have a longer string you can repeat your key until its long enough for example if your string was 1010010011 then you'd simple write your key twice and it would become 1011110111 and XOR it with the new string Here's a wikipedia link on the XOR …

WebDec 13, 2011 · Cryptography is implemented digitally. It is nice if values can't be of arbitrary size. If you work with modular arithmetic, you have guarantees about the largest value you will see and can allocate the correct amount of space to hold values. Share Improve this answer Follow answered Dec 12, 2011 at 15:08 PulpSpy 8,487 1 28 44 Add a comment 11 The primary reason XOR is so useful in cryptography is because it is "perfectly balanced"; for a given plaintext input 0 or 1, the ciphertext result is equally likely to be either 0 or 1 for a truly random key bit. The table below shows all four possible pairs of plaintext and key bits. It is clear that if nothing is known about … See more 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 For example where See more • Block cipher • Vernam cipher • Vigenère cipher See more The XOR operator is extremely common as a component in more complex ciphers.
