ObjectInputStream上的java.io.StreamCorruptedException,同时将它封装在Java中的CipherInputStream中
我通过套接字(单个客户端单个服务器)发送加密对象。客户端将加密对象作为密封对象发送,服务器将对象解密。但是在服务器端创建ObjectInputStream的过程中,它抛出了StreamCorruptedException异常。 我在网上搜了很多,我的代码看起来很好,但我不知道为什么抛出异常。ObjectInputStream上的java.io.StreamCorruptedException,同时将它封装在Java中的CipherInputStream中
这里是Client类:
package sample; import javax.crypto.Cipher;
import javax.crypto.CipherOutputStream;
import javax.crypto.SealedObject;
import javax.crypto.spec.SecretKeySpec;
import java.io.ObjectOutputStream;
import java.net.Socket;
public class Client {
private static Socket socket;
public static void main(String args[]) throws Exception {
socket=new Socket("127.0.0.1",7777);
Cipher cipher=Cipher.getInstance("AES/ECB/PKCS5Padding");
SecretKeySpec sks = new SecretKeySpec("MyDifficultPassw".getBytes(), "AES");
cipher.init(Cipher.ENCRYPT_MODE, sks);
CipherOutputStream cos=new CipherOutputStream(socket.getOutputStream(),cipher);
ObjectOutputStream oos=new ObjectOutputStream(cos);
oos.flush();
SealedObject sealedObject=new SealedObject("SampleString",cipher);
oos.writeObject(sealedObject);
}
}
这里是我的服务器类:
package sample; import javax.crypto.Cipher;
import javax.crypto.CipherInputStream;
import javax.crypto.CipherOutputStream;
import javax.crypto.SealedObject;
import javax.crypto.spec.SecretKeySpec;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class Server {
private static ServerSocket serverSocket;
public static SecretKeySpec sks;
public static void main(String args[]) throws Exception{
serverSocket=new ServerSocket(7777);
Socket clientSocket=serverSocket.accept();
Cipher cipher=Cipher.getInstance("AES/ECB/PKCS5Padding");
sks = new SecretKeySpec("MyDifficultPassw".getBytes(), "AES");
cipher.init(Cipher.DECRYPT_MODE, sks);
CipherInputStream cis=new CipherInputStream(clientSocket.getInputStream(),cipher);
ObjectInputStream ois=new ObjectInputStream(cis); //line 23
SealedObject so=(SealedObject) ois.readObject();
System.out.println((String)so.getObject(cipher));
}
}
及以下异常被抛出就当客户端连接服务器端:
Exception in thread "main" java.io.StreamCorruptedException: invalid stream header: 73720019 at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:857)
at java.io.ObjectInputStream.<init>(ObjectInputStream.java:349)
at sample.Server.main(Server.java:23)
回答:
问题是双重加密。输出案例中的密码必须密封对象,然后对流进行加密,但输入案例中的密码对象必须解密流,然后开封对象,这是相反的顺序。
删除SealedObject
或密码流。
