exclusive or operation

Exclusive or operation for encryption and decryption In an exclusive or operation, if a character (or value) x and a value m perform an exclusive or operation to obtain y, then use y and m to perform an exclusive or operation to restore x,

In this article, we will use the C language to implement the function of exchanging two variables of any type. It is difficult to use C for any type. If it is C ++, we can easily use the template function: template inline void swap(T& t1, T& t2)

The ^ operator in the PHP language is often used for encryption operations, and the decryption can also be done directly using ^, but when communicating with other languages, other languages such as objective-c may not be able to parse PHP's ^,

Bitwise exclusive or operation ^, operation ^ Bitwise xor (xor): If A xor B is equal to A and B, the result is 0. If the corresponding bits are not equal, the result is 1. Rule: A number is different from 0 or equal to itself: 0 ^ 0 = 0 1 ^ 0 = 1

In order to detect a single bit error, the data of every 256 bytes is divided into a 2048-bit table of 8 X, which uses the 22-bit verification code for verification and the 16-bit row verification code, perform horizontal verification. The six-digit
