uni-app vue3引入jsencrypt实现加密解密(PHP后端)

uniapp vue3版本引入jsencrypt实现加密解密,uniapp 引入jsencrypt实现前端加密及PHP后端解密

### uniapp中引入使用示例：
```javascript
import JSEncrypt from '/utils/jsencrypt.js'
const publicKey =`公钥`;

const encryptor = new JSEncrypt();
encryptor.setPublicKey(publicKey)//encryptor.setPrivateKey(RSA的私钥);

let passwordEncry = encryptor.encrypt('123456');//encryptor.decrypt(解密的内容);
console.log(passwordEncry);
```

### jsencrypt程序js文件
```javascript
