AES加解密(java android vue互通)

vue

本文用的加密模式为CBC,补码方式为PKCS5Padding(Vue对应的是PKCS7);

注意:不要导错包了,安卓端的base64导入的包是import android.util.Base64;
Java服务器端导入的base64包是import org.apache.commons.codec.binary.Base64;


Android端:

import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

// 秘钥,长度为16,和服务器端保持一致
private final static String defaultKey = "password12345678";
//AES是加密方式 CBC是工作模式 PKCS5Padding是填充模式(要和服务端保持一致)
private static final String CBC_PKCS5_PADDING = "AES/CBC/PKCS5Padding";
//填充值,16位的字符串,和服务器端保持一致
private static final String zeroIv = "1234567812345678";
// 前缀,可要可不要。

Vue端:

1.安装crypto-js :

npm install crypto-js --save-dev

2.代码:
import CryptoJS from "crypto-js";
import CryptoJS from '../utils/CryptoJS'

    // 加密

    encrypt(word, keyStr, ivStr) {

      // 秘钥,长度为16,和服务器端保持一致

      keyStr = keyStr ? keyStr : "password12345678";

      //填充值,16位的字符串,和服务器端保持一致

      ivStr = ivStr ? ivStr : "9769475569322011";

      let key = CryptoJS.enc.Utf8.parse(keyStr);

      let iv = CryptoJS.enc.Utf8.parse(ivStr);

      let srcs = CryptoJS.enc.Utf8.parse(word);

      let encrypted = CryptoJS.AES.encrypt(srcs, key, {

        iv,

        mode: CryptoJS.mode.CBC,

        padding: CryptoJS.pad.Pkcs7

      });

      return encrypted.toString();

    },

    // 解密

    decrypt(word, keyStr, ivStr) {

      // 秘钥,长度为16,和服务器端保持一致

      keyStr = keyStr ? keyStr : "password12345678";

      //填充值,16位的字符串,和服务器端保持一致

      ivStr = ivStr ? ivStr : "9769475569322011";

      var key = CryptoJS.enc.Utf8.parse(keyStr);

      let iv = CryptoJS.enc.Utf8.parse(ivStr);


      var decrypt = CryptoJS.AES.decrypt(word, key, {

        iv,

        mode: CryptoJS.mode.CBC,

        padding: CryptoJS.pad.Pkcs7

      });

      return decrypt.toString(CryptoJS.enc.Utf8);

    }
