我正在使用JAVA 8.我正在尝试使用客户端证书和证书树连接套接字服务器。
我有以下客户提供的信息:
我使用以下步骤创建了keystore.jks:
使用cat
使用私钥加密的组合文件中的Crested PKCS12文件(OpenSSL命令)
使用keytool生成的JKS密钥库文件
我使用以下步骤创建了trustore.jks:
我的示例代码如下:
package com.tutorial.exception.customize;
import javax.net.ssl.SSLHandshakeException;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
import java.io.*;
import java.security.cert.CertPathValidatorException;
import java.security.cert.CertificateException;
import java.util.Scanner;

public class Client {
public Client() {
System.setProperty("javax.net.ssl.keyStore", {keystore Location});
System.setProperty("javax.net.ssl.keyStorePassword", {password});
System.setProperty("javax.net.ssl.trustStore", {trustore location});
System.setProperty("javax.net.ssl.trustStorePassword", {password});
System.setProperty("javax.net.debug", "all");
System.setProperty( "sun.security.ssl.allowUnsafeRenegotiation", "true" );
}
public void connectHost(){
SSLSocketFactory sslSocketFactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
SSLSocket sslSocket = null;
try {
sslSocket = (SSLSocket) sslSocketFactory.createSocket(host, port);
sslSocket.setEnabledProtocols(new String[] {"TLSv1.2"});
sslSocket.startHandshake();
InputStream inputStream = sslSocket.getInputStream();
OutputStream outputStream = sslSocket.getOutputStream();
System.out.println("Sending request to Socket Server");
outputStream.write("Hello".getBytes());
outputStream.write("exit".getBytes());
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
int bytesRead = 0;
String messageString = "";
DataInputStream in = new DataInputStream(sslSocket.getInputStream());
while(!end)
{
bytesRead = in.read(messageByte);
messageString += new String(messageByte, 0, bytesRead);
if (messageString.length() == 100)
{
end = true;
}
}
System.out.println("MESSAGE: " + messageString);
// byte[] read = (byte[]) ois.readObject();
//String s2 = new String(read);
//System.out.println("" + s2);
//System.out.println("Message: " + message);
//close resources
//System.out.println(receive(inputStream));
}catch (IOException e) {
e.printStackTrace();
System.out.println("=====");
System.out.println(e.getMessage());
System.out.println("=====");
CertPathValidatorException ce = new CertPathValidatorException(e);
System.out.println("******");
System.out.println(ce.getIndex());
System.out.println(ce.getReason());
System.out.println("******");
//e.printStackTrace();
}
}
public static void main(String[] args){
new Client().connectHost();
}
}
我在执行代码后遇到异常:

在分析了日志之后,我发现了“clientHello”和“serverHello”消息,但是在该应用程序抛出上述异常之后。
我做错了什么?请指教。
谢谢, Somnath Guha
答案 0 :(得分:1)
在分析调试后,我已经找到了问题。
" BasicConstraints"服务器V3证书中缺少该证书,因此java无法将证书识别为有效证书。一旦添加了该约束,客户端就能够与服务器握手并能够与服务器通信。
