C#客户端与java服务器如何作SSL socket通讯，有没有能实现的牛人给下代码例程看看
参考GPT和自己的思路，以下是建立 C# 客户端与 Java 服务器之间的 SSL socket 通讯的详细代码示例：
Java 服务器端代码：
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import javax.net.ssl.SSLServerSocketFactory;
import javax.net.ssl.SSLSocketFactory;
public class SSLServer {
public static void main(String[] args) throws Exception {
int port = 8080;
// 加载 SSL 证书
System.setProperty("javax.net.ssl.keyStore", "server_keystore.jks");
System.setProperty("javax.net.ssl.keyStorePassword", "password");
// 创建 SSL socket 工厂
SSLServerSocketFactory sslServerSocketFactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
// 创建服务器 socket
ServerSocket serverSocket = sslServerSocketFactory.createServerSocket(port);
System.out.println("服务器已启动，监听端口：" + port);
while (true) {
// 等待客户端连接
Socket clientSocket = serverSocket.accept();
System.out.println("客户端已连接：" + clientSocket.getInetAddress());
// 创建输入输出流
BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
// 从客户端读取消息
String message = in.readLine();
System.out.println("接收到客户端的消息：" + message);
// 向客户端发送响应消息
out.println("服务器响应：" + message);
// 关闭流和客户端 socket
in.close();
out.close();
clientSocket.close();
}
}
}
C# 客户端代码：
using System;
using System.IO;
using System.Net.Security;
using System.Net.Sockets;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
using System.Text;
public class SSLClient {
public static void Main() {
int port = 8080;
// 创建 SSL 证书集合
X509CertificateCollection certCollection = new X509CertificateCollection();
certCollection.Add(new X509Certificate2("client_certificate.pfx", "password"));
// 创建 SSL 流
TcpClient client = new TcpClient("localhost", port);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
// 客户端认证
sslStream.AuthenticateAsClient("localhost", certCollection, SslProtocols.Tls12, false);
Console.WriteLine("客户端已连接服务器");
// 向服务器发送消息
string message = "你好，服务器！";
byte[] messageBytes = Encoding.UTF8.GetBytes(message);
sslStream.Write(messageBytes);
sslStream.Flush();
Console.WriteLine("已向服务器发送消息：" + message);
// 接收服务器的响应消息
byte[] buffer = new byte[2048];
int bytesRead = sslStream.Read(buffer, 0, buffer.Length);
string response = Encoding.UTF8.GetString(buffer, 0, bytesRead);
Console.WriteLine("接收到服务器的响应消息：" + response);
// 关闭 SSL 流和客户端 socket
sslStream.Close();
client.Close();
}
private static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) {
if (sslPolicyErrors == SslPolicyErrors.None) {
return true;
}
Console.WriteLine("SSL 证书验证失败：" + sslPolicyErrors);
return false;
}

下面是一个使用C#客户端和Java服务器进行SSL Socket通信的示例代码。请注意，此示例仅适用于演示目的，实际应用中需要进行更多的错误处理和安全措施。
C#客户端代码：
using System;
using System.IO;
using System.Net.Security;
using System.Net.Sockets;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
using System.Text;
class Program
{
static void Main(string[] args)
{
TcpClient client = new TcpClient("serverIpAddress", 8080);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
try
{
sslStream.AuthenticateAsClient("serverName", null, SslProtocols.Tls, false);
}
catch (AuthenticationException e)
{
Console.WriteLine("Exception: {0}", e.Message);
if (e.InnerException != null)
{
Console.WriteLine("Inner exception: {0}", e.InnerException.Message);
}
Console.WriteLine("Authentication failed - closing the connection.");
client.Close();
return;
}
string message = "Hello from the client!";
byte[] messageBytes = Encoding.UTF8.GetBytes(message);
sslStream.Write(messageBytes);
sslStream.Flush();
Console.WriteLine("Message sent: {0}", message);
byte[] buffer = new byte[2048];
int bytes;
while ((bytes = sslStream.Read(buffer, 0, buffer.Length)) > 0)
{
Console.WriteLine(Encoding.UTF8.GetString(buffer, 0, bytes));
}
client.Close();
}
private static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
return true;
Console.WriteLine("Certificate error: {0}", sslPolicyErrors);
// Do not allow this client to communicate with unauthenticated servers.
return false;
}
}
Java服务器代码：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.security.KeyStore;
import java.security.Security;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLServerSocketFactory;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.TrustManagerFactory;
public class Server {
public static void main(String[] args) throws Exception {
// Set up key manager to do server authentication
char[] passphrase = "password".toCharArray();
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(Server.class.getResourceAsStream("/keystore.jks"), passphrase);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, passphrase);
// Set up trust manager to do client authentication
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(ks);
// Set up SSL context
SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLServerSocketFactory sslServerSocketFactory = sslContext.getServerSocketFactory();
// Start server
ServerSocket serverSocket = sslServerSocketFactory.createServerSocket(8080);
System.out.println("Server started on port 8080");
while (true) {
// Accept client connections
SSLSocket socket = (SSLSocket) serverSocket.accept();
System.out.println("Client connected: " + socket.getInetAddress());
BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter writer = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));
// Receive message from client
String message = reader.readLine();
System.out.println("Message received: " + message);
// Send message back to client
writer.println("Message received: " + message);
writer.flush();
socket.close();
System.out.println("Client disconnected: " + socket.getInetAddress());
}
}
}
请注意，此示例假设存在一个名为“keystore.jks”的密钥库文件，其中包含服务器证书和私钥。您需要根据实际情况更改密码、密钥库和证书的位置。

在C#客户端和Java服务器之间进行SSL Socket通信，您需要在两边设置适当的SSL/TLS配置。以下是一个简单的示例：
Java服务器端代码：
javaCopy code
import javax.net.ssl.SSLServerSocket;
import javax.net.ssl.SSLServerSocketFactory;
import javax.net.ssl.SSLSocket;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
public class SSLServer {
public static void main(String[] args) {
int port = 12345;
try {
SSLServerSocketFactory sslServerSocketFactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
SSLServerSocket sslServerSocket = (SSLServerSocket) sslServerSocketFactory.createServerSocket(port);
System.out.println("SSL Server started on port " + port);
SSLSocket sslSocket = (SSLSocket) sslServerSocket.accept();
System.out.println("Client connected");
BufferedReader in = new BufferedReader(new InputStreamReader(sslSocket.getInputStream()));
PrintWriter out = new PrintWriter(sslSocket.getOutputStream(), true);
String line;
while ((line = in.readLine()) != null) {
System.out.println("Received from client: " + line);
out.println("Server response: " + line.toUpperCase());
}
in.close();
out.close();
sslSocket.close();
sslServerSocket.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
C#客户端代码：
csharpCopy code
using System;
using System.IO;
using System.Net.Security;
using System.Net.Sockets;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
using System.Text;
namespace SSLClient
{
class Program
{
static void Main(string[] args)
{
string serverAddress = "localhost";
int serverPort = 12345;
try
{
TcpClient client = new TcpClient(serverAddress, serverPort);
Console.WriteLine("Connected to server");
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
sslStream.AuthenticateAsClient(serverAddress);
StreamWriter writer = new StreamWriter(sslStream);
StreamReader reader = new StreamReader(sslStream);
string messageToSend = "Hello, Java SSL Server!";
Console.WriteLine("Sending: " + messageToSend);
writer.WriteLine(messageToSend);
writer.Flush();
string response = reader.ReadLine();
Console.WriteLine("Received: " + response);
client.Close();
}
catch (Exception e)
{
Console.WriteLine("Error: " + e.Message);
}
}
public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
return true;
Console.WriteLine("Certificate error: {0}", sslPolicyErrors);
return false;
}
}
}
在运行这些示例之前，您需要确保Java服务器已配置了SSL证书（通常为.keystore文件）。在实际应用中，您需要使用可信的CA签发的证书。同时，您可能需要在C#客户端中对服务器证书进行验证。
注意：这个示例提供了一个简单的实现，用于演示如何在C#客户端和Java服务器之间使用SSL Socket通信。在实际应用中，您可能需要根据具体需求调整代码，例如处理异常、添加超时
该回答引用ChatGPT4
要在 C# 客户端和 Java 服务器之间执行 SSL 套接字通信，您需要使用 TLS/SSL 建立安全通信。在此示例中，我们将使用自签名证书进行演示。但是，在生产中，您应该使用来自受信任的证书颁发机构 (CA) 的证书。
可以分为以下几个步骤
1、先生成证书，使用 keytool（包含在 Java 中）生成自签名证书：
keytool -genkey -alias selfsigned -keyalg RSA -keysize 2048 -validity 365 -keystore keystore.jks -storetype JKS -dname "CN=localhost, OU=OrgUnit, O=YourOrg, L=City, S=State, C=Country" -storepass changeit
2、创建 Java 服务器：
import javax.net.ssl.*;
import java.io.*;
import java.security.KeyStore;
public class SSLServer {
public static void main(String[] args) throws Exception {
int port = 12345;
String keystorePath = "keystore.jks";
String keystorePassword = "changeit";
KeyStore keyStore = KeyStore.getInstance("JKS");
keyStore.load(new FileInputStream(keystorePath), keystorePassword.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(keyStore, keystorePassword.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keyStore);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLServerSocketFactory sslServerSocketFactory = sslContext.getServerSocketFactory();
SSLServerSocket sslServerSocket = (SSLServerSocket) sslServerSocketFactory.createServerSocket(port);
sslServerSocket.setNeedClientAuth(false);
System.out.println("SSL Server is ready and waiting for a connection...");
SSLSocket sslSocket = (SSLSocket) sslServerSocket.accept();
BufferedReader in = new BufferedReader(new InputStreamReader(sslSocket.getInputStream()));
PrintWriter out = new PrintWriter(sslSocket.getOutputStream(), true);
String input;
while ((input = in.readLine()) != null) {
System.out.println("Received: " + input);
out.println("Echo: " + input);
}
in.close();
out.close();
sslSocket.close();
sslServerSocket.close();
}
}
3、创建 C# 客户端：
using System;
using System.IO;
using System.Net.Security;
using System.Net.Sockets;
using System.Security.Cryptography.X509Certificates;
namespace SSLClient {
class Program {
static void Main(string[] args) {
string serverIP = "localhost";
int port = 12345;
TcpClient client = new TcpClient(serverIP, port);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
try {
sslStream.AuthenticateAsClient(serverIP);
} catch (Exception e) {
Console.WriteLine("Authentication failed - closing the connection.");
client.Close();
return;
}
StreamWriter writer = new StreamWriter(sslStream);
StreamReader reader = new StreamReader(sslStream);
writer.WriteLine("Hello, Java SSL Server!");
writer.Flush();
Console.WriteLine("Sent: Hello, Java SSL Server!");
string response = reader.ReadLine();
Console.WriteLine("Received: " + response);
writer.Close();
reader.Close();
client.Close();
}
public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicy
以下答案由GPT-3.5大模型与博主波罗歌共同编写：
要在C#客户端和Java服务器之间通过SSL socket进行通信，需要使用C#中的SslStream和Java中的SSLSocket。
以下是一个简单的代码例程：
C#客户端：
using System;
using System.Net.Security;
using System.Net.Sockets;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
namespace SslClient
{
class Program
{
private static readonly string serverName = "example.com";
private static readonly int serverPort = 443;
private static readonly string certificateThumbprint = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
static void Main(string[] args)
{
TcpClient client = new TcpClient(serverName, serverPort);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
sslStream.AuthenticateAsClient(serverName);
// 进行SSL socket通讯，发送和接收数据的代码
sslStream.Close();
client.Close();
}
private static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
// 检查服务器证书是否与指定的证书指纹匹配
return certificate != null && certificate.GetCertHashString().Equals(certificateThumbprint, StringComparison.OrdinalIgnoreCase);
}
}
}
Java服务器：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.security.KeyStore;
import javax.net.ssl.*;
public class SslServer {
private static final int PORT = 443;
private static final String KEYSTORE_PATH = "path/to/keystore.jks";
private static final String KEYSTORE_PASSWORD = "keystore_password";
private static final String KEY_PASSWORD = "key_password";
public static void main(String[] args) {
try {
KeyStore keystore = KeyStore.getInstance("JKS");
keystore.load(SslServer.class.getResourceAsStream(KEYSTORE_PATH), KEYSTORE_PASSWORD.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(keystore, KEY_PASSWORD.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keystore);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLServerSocketFactory sslServerSocketFactory = sslContext.getServerSocketFactory();
SSLServerSocket sslServerSocket = (SSLServerSocket) sslServerSocketFactory.createServerSocket(PORT);
SSLSocket sslSocket = (SSLSocket) sslServerSocket.accept();
// 进行SSL socket通讯，发送和接收数据的代码
sslSocket.close();
sslServerSocket.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
