javascript使用cryptojs进行AES加密解密算法CBC模式

// 引入crypto-js包import CryptoJS from 'crypto-js'/** * AES加密 * @param {any} word 加密数据 */export const cryptoEncrypt = (word) => {  var key = CryptoJS.enc.Utf8.parse('填写密钥');  var iv = CryptoJS.enc.Utf8.parse('填写偏移量');  var encrypted = '';  if (typeof(word) == 'string') {      var srcs = CryptoJS.enc.Utf8.parse(word);      encrypted = CryptoJS.AES.encrypt(srcs, key, {          iv: iv,          mode: CryptoJS.mode.CBC,          padding: CryptoJS.pad.Pkcs7      });  } else if (typeof(word) == 'object') {//对象格式的转成json字符串      data = JSON.stringify(word);      var srcs = CryptoJS.enc.Utf8.parse(data);      encrypted = CryptoJS.AES.encrypt(srcs, key, {          iv: iv,          mode: CryptoJS.mode.CBC,          padding: CryptoJS.pad.Pkcs7      })  }  return encrypted.ciphertext.toString();}/** * AES解密 * @param {any} word 解密数据 */export const cryptoDecrypt = (word) => {  var key = CryptoJS.enc.Utf8.parse('填写密钥');  var iv = CryptoJS.enc.Utf8.parse('填写偏移量');  var encryptedHexStr = CryptoJS.enc.Hex.parse(word);  var srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);  var decrypt = CryptoJS.AES.decrypt(srcs, key, {      iv: iv,      mode: CryptoJS.mode.CBC,      padding: CryptoJS.pad.Pkcs7  });  var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);  return decryptedStr.toString();}
