上文讲了netty如何使用openssl生成的签名证书进行加密通信,结果客户端告诉我他们用的netty版本没有SslContextBuilder类,并且由于一些PY交易的原因还不能更新netty....
SslContextBuilder没有java你总有吧,来吧。
一、老规矩,创建key 1.创建客户端和服务端的keystore文件随便找个文件夹就行,打开命令行输入
keytool -genkey -alias sslserver -keystore sslserverkeys keytool -genkey -alias sslclient -keystore sslclientkeys2.将keystore导出证书格式
keytool -export -alias sslserver -keystore sslserverkeys -file sslserver.cer keytool -export -alias sslclient -keystore sslclientkeys -file sslclient.cer3.将客户端证书导入到服务器端信任的 keystore 里,将服务器端证书导入到客户端信任的 keystore 里。
keytool -import -alias sslclient -keystore sslservertrust -file sslclient.cer keytool -import -alias sslserver -keystore sslclienttrust -file sslserver.cer
最后得到有用的文件分别为
服务端:sslserverkeys、sslservertrust
客户端:sslclientkeys、sslclienttrust
