vue实现记住密码 JsEncrypt 加密 && Message too long for RSA

需求：前端实现记住密码将密码加密解密存储本地

安装

npm i --save jsencrypt

代码

import JsEncrypt from 'jsencrypt'

let enkey = '' //公钥  公钥私钥自己生成哦
//加密
export const encruption = (enkey, val) => {
   let encrypt = new JsEncrypt()  //新建JSEncrypt对象
   encrypt.setPublicKey(enkey) //设置公钥
   return encrypt.encrypt(val) //加密 
}
let deKey= '' //私钥
//解密
export const decryption  = (deKey，val) => {
   let encrypt = new JsEncrypt()
   encrypt.setPrivateKey(deKey) //私钥
   return encrypt.decrypt(val)  //解密
}

---------------------------------手动分割线----------------------------
报错啦 ！！！！“ Message too long for RSA”，因为加密的字符串太长，所以返回false

解决办法： encryptlong是一个基于jsencrypt扩展长文本分段加解密功能
1.encryptLong() 长文本加密
2.decryptLong() 长文本解密

首先安装

npm i encryptlong -S

修改后的代码

import { JSEncrypt } from 'encryptlong' //引用

//加密
export const encruption = (val) => {
    let encrypt = new JSEncrypt()
    encrypt.setPublicKey(enkey)
    return encrypt.encryptLong(val)
}
//解密
export const decryption  = (val) => {
    let encrypt = new JSEncrypt()
    encrypt.setPrivateKey(deKey)
    return encrypt.decryptLong(val)
}
