xor operation

After Encryption By CryptoAPI is used last time, OpenSSL is implemented this time. Motivation: After using CryptoAPI to create windows IE, Firefox, and chrome encryption controls, we need to add encrypted information to interact with

CRC-16 (Cyclic Redundancy error check)The CRC-16 error check program is as follows: Packet (only data bit, not the start bit, stop bit and optional parity bit) is considered as a continuous binary, its maximum valid bit (MSB) preferred sending. The

Core tip: Hong Sing's authcode function can be said to have made a significant contribution to the PHP community in China. Including Hong Sing's own products, and most of the companies that use PHP in China Use this function for encryption, Authcode

The BITBLT function declaration is as follows: BOOL BitBlt( HDC hdcDest, // handle to destination DC int nXDest, // x-coord of destination upper-left corner int nYDest, // y-coord of destination upper-left corner int nWidth, // width of

The XOR operation is represented by ^. The XOR operation is performed on integers a and B. When the two numbers have different binary locations, this bit is 1. Otherwise, it is 0. The exclusive or operation has a property: If a ^ B = c, c ^ B = a,

Exploration of bit operations and exploration of operationsPreface As the blogger keeps writing articles during the idle time of his work, only the exploration of bit operations here [begin. PS: Update Time: 2014-10-22. Some people did not

An array contains 2n + 1 integers, where n numbers appear twice and 1 number appears once. How many times does one appear? // Method 1: with the aid of an auxiliary array (the length is n + 1, and the element is a struct (including values and//

Input 1: Output 0; input 0: Output 1 I had an interview that day. I encountered such a problem: input 0, output 1, and input 1, and output 0. At that time, I came up with the first three methods. I was wondering if there were any other solutions. 1.

The following is a detailed summary of the description and function of various operational symbols in C #first, []square brackets ([]) are used for arrays, indexers, and properties, and also for pointers.1, the array type is a type followed by

In C #, you can perform a bitwise logical operation on an integer operand. The meaning of the bitwise logical operation is that each bit of the operand is taken sequentially, and the logical operation of each bit is the result of each bit of the

This article introduces an easy-to-use encryption and decryption algorithm: using an exclusive or (XOR) operation. This algorithm is simple in principle and aims to give readers a more intuitive impression on the encryption and decryption of

RAID (reduntdant Arrays of independent disk), Chinese meaning is an array of disks. Since 1988, Berkeley , published the paper "A Case for redundant Array of independent disk", it was intended to combine several inexpensive disks in a way that was
