Java實(shí)現(xiàn)SSL Socket長(zhǎng)連接方式
更新時(shí)間：2024年01月23日 14:53:01 作者：走馬川行雪
這篇文章主要介紹了Java實(shí)現(xiàn)SSL Socket長(zhǎng)連接方式,具有很好的參考價(jià)值,希望對(duì)大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教
一、單向認(rèn)證
1、生成服務(wù)端密鑰（配置了jdk的環(huán)境變量即可用keytool命令）
命令：keytool -genkey -keystore server_ks.jks -storepass server_password -keyalg RSA -keypass server_password
結(jié)果：會(huì)生成server_ks.jks密鑰文件
操作：將生成的server_ks.jks密鑰文件配置到服務(wù)端
2、生成服務(wù)端證書
命令：keytool -export -keystore server_ks.jks -storepass server_password -file server.cer
結(jié)果：會(huì)生成server.cer證書文件
操作：將生成的server.cer證書文件配置到客戶端
