The XOR operator is extremely common as a component in more complex ciphers. By itself, using a constant repeating key, a simple XOR cipher can trivially be broken using frequency analysis. If the content of any message can be guessed or otherwise known then the key can be revealed. Its primary merit is that it is … 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 primary reason XOR is so useful in cryptography is because it is "perfectly balanced"; for a given plaintext input 0 or 1, the ciphertext … See more Example using the Python programming language.

Web1 I understand what does to xor two bits (or booleans) means, but what's your definition of xoring strings ? – Thomas W. Sep 15, 2016 at 23:13 In C, a string is just an array of char with a NUL character at the end. str and str2 are arrays of six bytes. output is just one byte. So it's not clear what you're trying to accomplish. – user3386109 burlington swim and tennis club reviewsWebThe Vernam cipher, perfect cipher, One-time pad cipher or OTP is a cipher belonging to the group of polyalphabetic ciphers. It is considered to be the only proven cryptographic method that enables unconditionally secure encryption, which has been mathematically proven.
