RSA encrypt decrypt, js and Java

RSA 加密解密， 前后端密码交互

• 启动 ApplicationMain
• 访问 http://localhost:8080/login.html
• 登陆测试

前端

demo 位于 resources/static 目录下

获取jsencrypt.js

• cdn

<script src="https://cdn.bootcss.com/jsencrypt/2.3.1/jsencrypt.min.js"></script>

• 或者下载 http://travistidwell.com/jsencrypt/

• js代码

本地生成公钥密钥

openssl genrsa -out rsa_1024_priv.pem 1024

openssl rsa -pubout -in rsa_1024_priv.pem -out rsa_1024_pub.pem

# 查看私钥
cat rsa_1024_priv.pem
# 查看公钥
cat rsa_1024_pub.pem

JWT RSA 非对称加密的使用

参考： https://www.codeleading.com/article/9278493495/

@see com.stan.jwtdemo.JwtDemo.java

这里的key 需要使用将 rsa_private.pem 转换

openssl pkcs8 -topk8 -inform PEM -in rsa_private.pem -outform pem -nocrypt -out pkcs8Private.key
