1: A company uses a public telephone to pass data, and the data is a four-bit integer that is encrypted during delivery.The encryption rules are as follows: Each digit is prefixed with 5, and the remainder is replaced with and divided by 10, then the first and fourth bits are exchanged, and the second and third bits are exchanged.Package Cn.zzsxt.lianxi;Import Java.util.Scanner;public class Practice {public static void Main (string[] args) {System.out

Put the code first. There are two files: AES. php (aes algorithm file) and aesDemo. php (application instance file) aesDemo. php: Example, The Code is as follows: Require_once ('./AES. php ');// $ Aes = new AES ();$ Aes = new AES (true); // stores encrypted strings in hexadecimal format.// $ Aes = new AES (true, true); // The encrypted string is stored in hexadecimal format with debugging information$ Key = "this is a 32 byte key"; // key$ Keys =

This article mainly introduces the SHA-256 encryption algorithm implemented by Javascript, analyzes the specific steps and related skills of JavaScript to implement SHA-256 encryption in the form of a complete example, A friend can refer to the example of this article describes the Javascript implementation of the SHA-

This article illustrates the PHP code encryption and decryption class based on PHP implementation. Share to everyone for your reference, specific as follows: PHP code encryption class, you can change according to their needs, the original class such as, the example in Ubuntu under the Test no problem.
