本篇内容主要讲解“Netty与Qt如何实现wss双向认证”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Netty与Qt如何实现wss双向认证”吧!

Netty 4.1.42.Final + Qt 5.9 + SpringBoot2.1.8

一、证书准备

要使用ssl双向验证，就必须先要生成服务端和客户端的证书，并相互添加信任，具体流程如下(本人调试这个用例的时候，花了很多时间来验证证书是否正确，以及握手失败的原因，这里证书生成过程只要按流程走，本人能保证绝对没有问题) 现在打开cmd，在哪个目录下打开，证书就会放在哪个目录下：

第一步:生成Netty服务端私钥和证书仓库命令

keytool -genkey -alias securechat -keysize 2048 -validity 365 -keyalg RSA -dname "CN=localhost" -keypass sNetty -storepass sNetty -keystore sChat.jks -deststoretype pkcs12

-keysize 2048 密钥长度2048位（这个长度的密钥目前可认为无法被暴力破解）
-validity 365 证书有效期365天
-keyalg RSA 使用RSA非对称加密算法
-dname "CN=localhost" 设置Common Name为localhost
-keypass sNetty密钥的访问密码为sNetty
-storepass sNetty密钥库的访问密码为sNetty（其实这两个密码也可以设置一样，通常都设置一样，方便记）
-keystore sChat.jks 指定生成的密钥库文件为sChata.jks
-deststoretype pkcs12 必须要pkcs12

第二步：生成Netty服务端自签名证书

keytool -export -alias securechat -keystore sChat.jks -storepass sNetty -file sChat.cer

第三步：生成客户端的密钥对和证书仓库，用于将服务端的证书保存到客户端的授信证书仓库中

keytool -genkey -alias smcc -keysize 2048 -validity 365 -keyalg RSA -dname "CN=localhost" -keypass sNetty -storepass sNetty -keystore cChat.jks -deststoretype pkcs12

第四步：将Netty服务端证书导入到客户端的证书仓库中

keytool -import -trustcacerts -alias securechat -file sChat.cer -storepass sNetty -keystore cChat.jks

第五步:生成客户端自签名证书

keytool -export -alias smcc -keystore cChat.jks -storepass sNetty -file cChat.cer

最后一步:将客户端的自签名证书导入到服务端的信任证书仓库中：

keytool -import -trustcacerts -alias smcc -file cChat.cer -storepass sNetty -keystore sChat.jks

到这里，证书就生成完毕了，我们就可以得到两个jks文件，一个是服务端的sChat.jks ，一个是客户端的cChat.jks ,这两个文件后面初始化sslCOntext的时候会用到
