Take a brief look at the concept of encryption before implementing this example, encryption is defined by some special way, has changed the content of the information, the unauthorized users even get the encrypted information, if there is no correct decryption method can not get the information. When it comes to the topic of encryption, some readers will be very interested, and will associate the complex encryption algorithm. This example mainly uses XOR "^" operator to realize the function of digital encryption simply.
