有人可以告诉我我在这段代码中做错了什么吗？服务器端似乎正在工作。一旦我为服务器端运行代码，服务器就会等待客户端请求连接。然后，当我运行客户端代码时，它会在客户端引发以下异常：

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
    at sun.security.ssl.Alerts.getSSLException(Unknown Source)
    at sun.security.ssl.Alerts.getSSLException(Unknown Source)

    at ClientSideMain.main(ClientSideMain.java:5)
Press any key to continue . . .

以及服务器端的以下异常：

服务器端代码

public class ServerSide
{
ServerSocket serverSocket;
Socket regSocket;
Hashtable<String,User> userList;
CTC tempCTC;
File f;
DataInputStream in;
BufferedReader br;

SSLContext sslContext;
KeyManagerFactory keyManagerFactory;
KeyStore keyStore;
char[] keyStorePassphrase;

SSLServerSocketFactory sslServerSocketFactory;
SSLServerSocket sslServerSocket;
SSLSocket sslNormalSocket;

ServerSide()
{
    f = new File("userlist.txt");
    userList = new Hashtable<String, User>();
    loadUsers(f);

    try
    {
        sslContext = SSLContext.getInstance("SSL");
        keyManagerFactory = KeyManagerFactory.getInstance("SunX509");
        keyStore = KeyStore.getInstance("JKS");
        keyStorePassphrase = "passphrase".toCharArray();
        keyStore.load(new FileInputStream("testkeys"), keyStorePassphrase);
        keyManagerFactory.init(keyStore, keyStorePassphrase);
        sslContext.init(keyManagerFactory.getKeyManagers(), null, null);
        sslServerSocketFactory = (SSLServerSocketFactory)SSLServerSocketFactory.getDefault();

        sslServerSocket = (SSLServerSocket)sslServerSocketFactory.createServerSocket(12345);

        try{Thread.sleep(1000);}catch(Exception e){}

        while(true)
        {
            sslNormalSocket = (SSLSocket)sslServerSocket.accept();
            tempCTC = new CTC(sslNormalSocket, userList, f);
        }
    }
    catch(IOException ioe)
    {
        ioe.printStackTrace();
    }
    catch(NoSuchAlgorithmException nsae)
    {
        nsae.printStackTrace();
    }
    catch(KeyStoreException kse)
    {
        kse.printStackTrace();
    }
    catch(CertificateException ce)
    {
        ce.printStackTrace();
    }
    catch(UnrecoverableKeyException uke)
    {
        uke.printStackTrace();
    }
    catch(KeyManagementException kme)
    {
        kme.printStackTrace();
    }
}

客户端代码（发生异常的地方）

private void doConnectToServer()
{
    SSLSocketFactory        sslSocketFactory;
    KeyManagerFactory       keyManagerFactory;
    SSLContext              sslContext;
    KeyStore                keyStore;
    char[]                  keyStorePassphrase;
    SSLSocket               sslSocket;

    try
    {
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

        System.setProperty("javax.net.ssl.trustStore", "samplecacerts");
        System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

        sslContext = SSLContext.getInstance("SSL");
        keyManagerFactory = KeyManagerFactory.getInstance("SunX509");
        keyStore = KeyStore.getInstance("JKS");

        keyStorePassphrase = "passphrase".toCharArray();
        keyStore.load(new FileInputStream("testkeys"), keyStorePassphrase);

        keyManagerFactory.init(keyStore, keyStorePassphrase);
        sslContext.init(keyManagerFactory.getKeyManagers(), null, null);

        sslSocketFactory = sslContext.getSocketFactory();

        sslSocketFactory = (SSLSocketFactory)SSLSocketFactory.getDefault();

        sslSocket = (SSLSocket)sslSocketFactory.createSocket("127.0.0.1", 12345);

        sslSocket.startHandshake(); //line that throws the exception

        cts = new CTS(sslSocket, this);
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}

似乎您在双方（服务器/客户端）上都没有相同的加密方法。

Caused by: javax.net.ssl.SSLHandshakeException: no cipher suites in common

确保你在两边都使用相同的。
