上文講了netty如何使用openssl生成的簽名證書進行加密通訊,結果客戶端告訴我他們用的netty版本沒有SslContextBuilder類,而且因爲一些PY交易的緣由還不能更新netty....
html
SslContextBuilder沒有java你總有吧,來吧。java
隨便找個文件夾就行,打開命令行輸入git
keytool -genkey -alias sslserver -keystore sslserverkeys keytool -genkey -alias sslclient -keystore sslclientkeys
keytool -export -alias sslserver -keystore sslserverkeys -file sslserver.cer keytool -export -alias sslclient -keystore sslclientkeys -file sslclient.cer
keytool -import -alias sslclient -keystore sslservertrust -file sslclient.cer keytool -import -alias sslserver -keystore sslclienttrust -file sslserver.cer
最後獲得有用的文件分別爲
服務端:sslserverkeys、sslservertrust
客戶端:sslclientkeys、sslclienttrustsegmentfault
