我完全被困在这里。我有一个需要使用自签名证书连接到SSL服务器的java客户端代码。
当我在服务器端禁用SSLv2支持时，会出现仅问题。
private static DefaultHttpClient createHttpClient(int port) {
try {
java.lang.System.setProperty(
"sun.security.ssl.allowUnsafeRenegotiation", "true");
// First create a trust manager that won't care.
X509TrustManager trustManager = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
// Don't do anything.
}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
// Don't do anything.
}
public X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[0];
}
};
// Now put the trust manager into an SSLContext.
// Supported: SSL, SSLv2, SSLv3, TLS, TLSv1, TLSv1.1
SSLContext sslContext = SSLContext.getInstance("SSLv3");
sslContext.init(null, new TrustManager[] { trustManager },
new SecureRandom());
// Use the above SSLContext to create your socket factory
// (I found trying to extend the factory a bit difficult due to a
// call to createSocket with no arguments, a method which doesn't
// exist anywhere I can find, but hey-ho).
SSLSocketFactory sf = new SSLSocketFactory(sslContext);
// Accept any hostname, so the self-signed certificates don't fail
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
// Register our new socket factory with the typical SSL port and the
// correct protocol name.
//Scheme httpsScheme = new Scheme("https", sf, port);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("https", sf, port));
HttpParams params = new BasicHttpParams();
ClientConnectionManager cm = new SingleClientConnManager(params,
schemeRegistry);
return new DefaultHttpClient(cm, params);
} catch (Exception ex) {
Log.error("ERROR Creating SSL Connection: " + ex.getMessage());
return null;
}
}

在服务器端，我可以看到下一条痕迹：
info sock48 handshake start {before/accept initialization}
info sock48 accept loop {before/accept initialization}
info sock48 accept exit {SSLv3 read client hello B}
error sock48 {wrong version number}
如果我启用SSL2，那么我会看到
info sock47 handshake start {before/accept initialization}
info sock47 accept loop {before/accept initialization}
info sock47 accept loop {SSLv3 read client hello A}
info sock47 accept loop {SSLv3 write server hello A}
info sock47 accept loop {SSLv3 write certificate A}
info sock47 accept loop {SSLv3 write server done A}
info sock47 accept loop {SSLv3 flush data}
info sock47 accept exit {SSLv3 read client certificate A}
info sock47 accept exit {SSLv3 read client certificate A}
info sock47 accept loop {SSLv3 read client key exchange A}
info sock47 accept loop {SSLv3 read finished A}
info sock47 accept loop {SSLv3 write change cipher spec A}
info sock47 accept loop {SSLv3 write finished A}
info sock47 accept loop {SSLv3 flush data}
info sock47 handshake done {SSL negotiation finished successfully}
info sock47 accept exit {SSL negotiation finished successfully}
info sock47 alert write {close notify}
一切正常。
我也知道这不是服务器端的东西，因为与其他软件的连接工作正常。
知道我做错了什么吗？
也有人知道这个“读客户端你好A / B”是什么意思吗？
由于
更新 - 修正
SSLSocketFactory需要被这个新的TLSSocketFactory替换。
public class TLSSocketFactory extends SSLSocketFactory {
private final javax.net.ssl.SSLSocketFactory socketfactory;
public TLSSocketFactory(SSLContext sslContext) {
super(sslContext);
this.socketfactory = sslContext.getSocketFactory();
}
public Socket createSocket() throws IOException {
SSLSocket socket = (SSLSocket) super.createSocket();
socket.setEnabledProtocols(new String[] {"SSLv3, TLSv1"});
return socket;
}
public Socket createSocket(
final Socket socket,
final String host,
final int port,
final boolean autoClose
) throws IOException, UnknownHostException {
SSLSocket sslSocket = (SSLSocket) this.socketfactory.createSocket(
socket,
host,
port,
autoClose
);
sslSocket.setEnabledProtocols(new String[] {"SSLv3", "TLSv1"});
getHostnameVerifier().verify(host, sslSocket);
return sslSocket;
}
}
答案 0 :(得分：5)
从客户端启用的协议列表中删除SSLv2ClientHello。
