uniapp小程序使用RSA加密解密的操作代码

1.安装wxmp-rsa

npm i wxmp-rsa -S

2.新建rsa.js文件

import WxmpRsa from 'wxmp-rsa'

//公钥和私钥换自己的
// 定义公钥
const publicKey = `
  -----BEGIN PUBLIC KEY-----
  MIGeMA0GCSqGSIb3DQEBAQUAA4GMADCBiAKBgFnWSUwsmGawhMJ30z6y5li2jcf1

// 定义私钥
const privateKey = `

`

//加密
function getRsaCode(str) {
	const rsa = new WxmpRsa()
	rsa.setPublicKey(PUBLIC_KEY);
	const data = rsa.encryptLong(str)
	return data
}
//解密
function getRsaDeCode(str) {
	const rsa = new WxmpRsa()
	rsa.setPrivateKey(PRIVATE_KEY);
	const data = rsa.decryptLong(str)
	return data
}

export default {
	getRsaCode,
	getRsaDeCode,
};

3.页面使用

//引入
import rsa from '../../common/rsa.js';

let str = {name:'老王'}
//加密
let a=rsa.getRsaCode(JSON.stringify(str)) //注意要转为字符串
console.log(a)
//解密
let b=rsa.getRsaDeCode(a)
console.log(b)
