WebWhat is the XOR cipher? (Definition) XOR encryption is a symmetrical encryption/decryption method based on the use of the logical/binary operator XOR (also called Exclusive Or, symbolized by ⊕ ). The XOR cipher uses as operands the plain text and the key (previously encoded in binary/bit string). WebExclusive-OR encryption works by using the boolean algebra function exclusive-OR (XOR). XOR is a binary operator (meaning that it takes two arguments - similar to the addition sign, for example). By its name, exclusive-OR, it is easy to infer (correctly, no less) that it will return true if one, and only one, of the two operators is true. mcdonald\\u0027s delivery postmatesWebJul 15, 2024 · return bytes ( [i ^ j for i, j in zip (first, second)]) # Convert two byte strings to their xor product Strongly-typed results best = { 'message': currentString, 'num_chars': num_chars, 'key': byte } If you're only doing this because you need to return multiple things, idiomatic Python is to simply return them as a tuple, i.e. mcdonald\u0027s delivery iasi
