vue 参数的简单AES加密

分享下我的AES小dome, 话不多说,直接上代码

 

1.vue环境 

 

2.编写加密,解密工具js

/**
* 工具类
*/
import Vue from 'vue'
import CryptoJS from 'crypto-js'
// 默认的 KEY 与 IV
const KEY = CryptoJS.enc.Utf8.parse("dufy20170329java");
const IV = CryptoJS.enc.Utf8.parse("dufy20170329java");

export default {//加密
  encrypt(word, keyStr, ivStr){
    let key = KEY
    let iv = IV

    if(keyStr&&ivStr){
      console.log('----自定义---key,iv')
      key = CryptoJS.enc.Utf8.parse(keyStr);
      iv = CryptoJS.enc.Utf8.parse(ivStr);
    }
    let srcs = CryptoJS.enc.Utf8.parse(word);
    var encrypted = CryptoJS.AES.encrypt(srcs, key, {
      iv: iv,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.ZeroPadding
    });
    return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);
},

  //解密
decrypt(word, keyStr, ivStr){ let key = KEY let iv = IV if(keyStr&&ivStr){    key = CryptoJS.enc.Utf8.parse(keyStr);    iv = CryptoJS.enc.Utf8.parse(ivStr); }
  let base64
= CryptoJS.enc.Base64.parse(word);   let src = CryptoJS.enc.Base64.stringify(base64);   var decrypt = CryptoJS.AES.decrypt(src, key, {     iv: iv,     mode: CryptoJS.mode.CBC,     padding: CryptoJS.pad.ZeroPadding   }) var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8); return decryptedStr.toString(); }
}

 

 

3.vue页面引用   

 import Utils from '@/encrytUtils.js'

   Utils.encrypt(this.content)

 

4.后端代码

java 代码,Aes加密解密工具类

    }

    public static String desEncrypt(String data, String key, String iv) throws Exception {

            return originalString;
        } catch (Exception e) {
            return null;
        }
    }

    /**
    * 使用默认的key和iv加密

        return encrypt(data, KEY, IV);
    }
