C＃客户端连接到一个Java服务器通过SSL

Question

作为一个团队项目，我需要从C＃客户端连接到一个Java 6.5 SSL服务器，但是当我得到它挂stream.AuthenticateAsClient线。

C＃代码连接

public static void connect(string server, Int32 port)
{
  try
  {
    client = new TcpClient(server, port);
    stream = new SslStream(client.GetStream(), false);
    stream.AuthenticateAsClient("MyCNfield");
...
...

如果我连接到像https://mail.google.com并设置MyCNfield到mail.google.com，它工作得很好，所以我认为它是Java端。

Java的初始化部分是：

public void initSSL() throws IOException, KeyStoreException, NoSuchAlgorithmException,
                             CertificateException, UnrecoverableKeyException, KeyManagementException {
    char[] passphrase = "scared".toCharArray();
    System.out.println(java.security.KeyStore.getDefaultType());
    boolean handshakedone=false;

    KeyStore keystore1 = KeyStore.getInstance("jks");
    FileInputStream fis = new FileInputStream("C:\\\\temp\\\\work.jks");
    keystore1.load(fis, passphrase);
    fis.close();
    KeyStore ksTrust = KeyStore.getInstance("jks");
    FileInputStream fis2 =  new FileInputStream("C:\\\\temp\\\\work.jks");
    ksTrust.load(fis2, passphrase);

    KeyManagerFactory kmf =    KeyManagerFactory.getInstance("SunX509");

    // KeyManager's decide which key material to use.
    kmf.init(keystore1, passphrase);

    // TrustManager's decide whether to allow connections.
    TrustManagerFactory tmf =   TrustManagerFactory.getInstance("SunX509");
    tmf.init(ksTrust);

    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null);

    SSLServerSocketFactory sslserversocketfactory =(SSLServerSocketFactory) sslContext.getServerSocketFactory();
    sslserversocket =(SSLServerSocket) sslserversocketfactory.createServerSocket(2443);
    sslserversocket.setUseClientMode(false);

    //Context conte
    ServerSocketFactory serversocketfactory =(ServerSocketFactory) sslContext.getServerSocketFactory();

    //  serverSocket = new ServerSocket(2443);
    System.out.println("OK we are set up");
}

它被调用：

sslsocket = (SSLSocket) sslserversocket.accept();

和继续进行，即使连接没有充分验证。

有什么需要改变，以解决这个问题：JKS将有由我创建了一个CA签名的证书MyCNfield。如何既导入证书链，以我私人的CA在我的C＃，或者我怎么excange Java和C＃的自签名的证书，只是扔掉我现在JKS？

您需要使用RemoteCertificateValidationCallback回调机制来提供证书认证。你不应该关闭的问题，这是一个有效的问题，很多人可能有。这个答案是在谷歌搜索的第一命中一个，这要归功于计算器伟大的搜索引擎优化，所以它可能会导致人们走上错误的道路。

使用的 RemoteCertificateValidationCallback 回调函数。

private readonly bool allowSsl;

// callback used to validate the certificate in an SSL conversation
private static bool ValidateRemoteCertificate(
object sender,
    X509Certificate certificate,
    X509Chain chain,
    SslPolicyErrors policyErrors
)
{
    if (allowSsl)
    {
        // allow any certificate...
        return true;
    }
    else
    {
        return policyErrors == SslPolicyErrors.None;
    }
}

这是你将如何使用的TcpClient 使用它：

TcpClient client = new TcpClient(machineName,443);
Console.WriteLine("Client connected.");

// Create an SSL stream, specifying the callback above.
SslStream sslStream = new SslStream(
    client.GetStream(), 
    false, 
    new RemoteCertificateValidationCallback (ValidateRemoteCertificate), 
    null
    );
