使⽤CBC + PKCS5Padding + HEX 加解密

前端代码

key 自主生成
iv 自主生成
import CryptoJS from "crypto-js";
// 加密
export function Encrypt(word) {
  let key = '';
  let iv = '';
  key = CryptoJS.enc.Utf8.parse(key);
  iv = CryptoJS.enc.Utf8.parse(iv);
  let str = ''
  if (typeof (word) == 'string') {
    str = word
  } else if (typeof (word) == 'object') {
    str = JSON.stringify(word);
  }
  let srcs = CryptoJS.enc.Utf8.parse(str);
  // 加密模式为CBC，补码方式为PKCS5Padding（也就是PKCS7）
  let encrypted = CryptoJS.AES.encrypt(srcs, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
  });
  //返回Hex
  return CryptoJS.enc.Hex.stringify(encrypted.ciphertext);
}

// 解密
export function Decrypt(word) {
  let key = '';
  let iv = '';
  key = CryptoJS.enc.Utf8.parse(key);
  iv = CryptoJS.enc.Utf8.parse(iv);
  let base64 = CryptoJS.enc.Hex.parse(word);
  let src = CryptoJS.enc.Base64.stringify(base64);
  // 解密模式为CBC，补码方式为PKCS5Padding（也就是PKCS7）
  let decrypt = CryptoJS.AES.decrypt(src, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
  });
  let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
  return decryptedStr.toString();
}
