微信小程序:3DES加密解密

3DES加密解密  

encryptDES.js主要代码如下：

var CryptoJS = CryptoJS || function(u, l) {

... ...


var encrypt = function() {
  var secretKey = "1!QAZ2@WSXCDE#3$4RFVBGT%5^6YHNMJU7&8*IK<.LO9(0P";
  var ivKey = "12481632";
  var encryptByDES = function encryptByDES(message) {
    var keyHex = CryptoJS.enc.Utf8.parse(secretKey);
    var ivHex = CryptoJS.enc.Utf8.parse(ivKey);
    var encrypted = CryptoJS.TripleDES.encrypt(message, keyHex, {
      iv: ivHex,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7
    });
    return encrypted.toString();
  };
  var decryptByDES = function decryptByDES(ciphertext) {
    var keyHex = CryptoJS.enc.Utf8.parse(secretKey);
    var ivHex = CryptoJS.enc.Utf8.parse(ivKey);
    var decrypted = CryptoJS.TripleDES.decrypt(ciphertext, keyHex, {
      iv: ivHex,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7
    });
    return decrypted.toString(CryptoJS.enc.Utf8);
  };

  return {
    encryptByDES: encryptByDES,
    decryptByDES: decryptByDES
  };
}();

module.exports = {
  encryptByDES: encrypt.encryptByDES,
  decryptByDES: encrypt.decryptByDES
}

在项目中应用：

var encrypt = require('../../utils/encryptDES.js');

var params = encrypt.encryptByDES(data);   //3des加密

var result = encrypt.decryptByDES("需要解密的字符串");   //3DES解密
