将握手信息使用通信密码加密并使用hash算法进行计算。----6. 使用私钥进行加密获取通信密码。对握手信息使用私钥进行加密并通过hash比对通信秘密的正确性, hash握手信息使用通信密码进行加密7.使用通信密码进行解密握手信息同时计算hash确认双发的通信密钥是一样的。--8. 握手结束使用通信秘密进行加密--http 握手在TCP/IP协议中TCP协议提供可靠的连接服务采用三次握手建立一个连接。第一次握手建立连接时客户端发送syn包(synj)到服务器并进入SYN_SEND状态等待服务器确认第二次握手服务器收到syn包必须确认客户的SYN(ackj1)同时自己也发送一个SYN包(synk)即SYNACK包此时服务器进入SYN_RECV状态 第三次握手客户端收到服务器的SYNACK包向服务器发送确认包ACK(ackk1)此包发送完毕客户端和服务器进入ESTABLISHED状态完成三次握手。 完成三次握手客户端与服务器开始传送数据.http端口80 https 443tomcat 开启https生成证书 如果没有的话keytool -genkey -alias tomcat -keyalg RSA 在user目录下(mac).keystore 文件填写一些信息就可以了今天tomcat 的配置文件进行配置 server.xmlmaxThreads150 SSLEnabledtrue schemehttps securetrue keystoreFile${user.home}/.keystore keystorePass_密码_ clientAuthfalse sslProtocalTLS启动tomcat 进入https://localhost:8443 , 信任证书后看见tomcat就配置成功了。android UrlConnection 使用https把证书放在assets文件下打开应该是这样的-----BEGIN
