rsa 加密(已经做成js 可以随便使用)默认支持大数据分块加密,支持私玥加密,公玥解密-公玥加密,私玥解密.

基于jsencrypt 的修改.
直接引用 import RSAEncrypt from '@/common/rsa.js';
中文大数据加密需要把数据转换位base64

var rsa=new RSA();  
//生成私玥  
var pri=rsa.Key.private();  
//生成公玥  
var pub=rsa.Key.public();  
//待加密的数据,中文base64之后的.自己base64解码后就是原始数据,这里已经超过512了.

附近里面2个js 一个rsa.js 可以直接使用.
另一个是 修改过后的jsencrypt.js
导入到 common文件夹 引入 rsa.js 就OK

欢迎技术交流.
