Java Webstart 信任库 SSL

Question

需要一些指导。

我有 java webstart 应用程序，我希望它通过 SSL 连接到服务器。只需添加一个属性，例如：System.setProperty("javax.net.ssl.trustStore","my.keystore");但是由于 JAWS 程序是从服务器下载的文件不起作用，并且本地文件系统上没有 my.keystore。因此决定将证书分发给所有客户。我执行了以下操作并且成功了。

1. 将此信任存储作为流读取（使用 getResourceAsStream 方法）。
2. 将其保存在客户端计算机上的任何文件中（sometemp）
3. Call System.setProperty ("javax.net.ssl.trustStore", trustStorePath);

但我确信一定有比这更好的解决方案。有什么想法可以让它变得更好吗？

public boolean validateUserFromActiveDirectory(String userId) {
                    final String MEMBER_GROUP = "CN=asdadasd,OU=asdasdasd Accounts,OU=adasdas,OU=asdasdas,DC=asdasdas,DC=asdasdas,DC=adasdasd,DC=asdasdasd";
            String employeeNumber = "";
            final String LDAP_INIT_CTX = "com.sun.jndi.ldap.LdapCtxFactory";
            final String LDAP_URL = "ldap://xx-ssssssss.eee.eee.eeeee.eeeee:636";
            final String MY_ATTRS[] = { "employeeNumber" };
            String adminPassword = "somepassword";
            String securityProtocol = "ssl";
            boolean isValidUser = false;
            try {

                  Hashtable env = new Hashtable();
                  env.put(Context.INITIAL_CONTEXT_FACTORY, LDAP_INIT_CTX);
                  env.put(Context.PROVIDER_URL, LDAP_URL);
                  env.put(Context.SECURITY_AUTHENTICATION, "simple");
                  env.put(Context.REFERRAL, "follow");
                  env.put(Context.SECURITY_PRINCIPAL, MEMBER_GROUP);
                  env.put(Context.SECURITY_CREDENTIALS, adminPassword);
                  env.put(Context.SECURITY_PROTOCOL, securityProtocol);

            //C:\Documents and Settings\yourusername\Local Settings\Temp
            File tf = File.createTempFile("someTruststore", ".jks");
            tf.deleteOnExit();
            byte buffer[] = new byte[0x1000];
               ClassLoader cl = JNDI.class.getClassLoader();
            InputStream in = cl.getResourceAsStream(
                    "someTruststore.jks");
            FileOutputStream out = new FileOutputStream(tf);
            int cnt;
            while ((cnt = in.read(buffer)) != -1)
                out.write(buffer, 0, cnt);
            in.close();
            out.close();
            System.setProperty("javax.net.ssl.trustStore", tf
                            .getAbsolutePath());

                  DirContext context = new InitialLdapContext(env, null);
                  SearchControls searchControls = new SearchControls();
                  searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
                  NamingEnumeration results = context.search(
                              "XX=ent,XX=abc,XX=aaaaa,XX=aaaa", "(sAMAccountName="
                                          + userId + ")", searchControls);

                  if (results != null && results.hasMore()) {
                      //some logic

                        }
                  }
            } catch (Exception e) {
                  e.printStackTrace();
            }
            return isValidUser;
      }

Laz 感谢您的耐心，当我有时间时尝试学习。 我开始编写自己的 CustomSSLSocketFactory..现在我正在绕过安全性...基于白金解决方案的示例。如果我这样做...信息会以明文形式在网络上传递吗？

现在我想知道我应该如何处理我拥有“sometruststore.jks”文件的信任库文件。我该怎么办……我有编写自己的自定义信任管理器软件吗？ 请引导我正确的方向。

您无需依赖系统属性和文件系统即可完成此操作。像您正在做的那样将密钥库作为流读取并创建您自己的 SSLSocketFactory 会更干净。

import java.net.URL;
import java.security.KeyStore;
import java.security.SecureRandom;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManagerFactory;

...

    // assume keyStore is the KeyStore you read via getResourceAsStream
    final TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("SunX509");
    trustManagerFactory.init(keyStore);

    final SSLContext context = SSLContext.getInstance("SSL");
    context.init(null, trustManagerFactory.getTrustManagers(), new SecureRandom());

    final URL url = new URL("https://whatever");
    final HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
    urlConnection.setSSLSocketFactory(context.getSocketFactory());

...

我还没有验证，但我认为没有理由不能通过 Webstart 来实现。

更新：

您提到您正在寻求连接到 Active Directory，所以我猜您将使用 LDAPS 作为协议？如果是这样，也许 此 URL 处的代码可以作为灵感？您必须创建 javax.net.ssl.SSLSocketFactory（请参阅 Platinumsolutions 链接中的 BlindSSLSocketFactoryTest），它包装了上面创建 SSLContext 的逻辑 并将调用委托给 context.getSocketFactory() 创建的 SSLSocketFactory。

public class TrustedSSLSocketFactory extends SSLSocketFactory {
    private static SSLContext context;
    public static void initTrustedSSLSocketFactory(final KeyStore keyStore) throws Exception {
        final TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("SunX509");
        trustManagerFactory.init(keyStore);

        final SSLContext context = SSLContext.getInstance("SSL");
        context.init(null, trustManagerFactory.getTrustManagers(), new SecureRandom());
    }

    public static SocketFactory getDefault() {
        return context.getSocketFactory();
    }

    public Socket createSocket(String arg0, int arg1) throws IOException, UnknownHostException {
        return trustedFactory.createSocket(arg0, arg1);
    }

    public Socket createSocket(InetAddress arg0, int arg1) throws IOException {
        return trustedFactory.createSocket(arg0, arg1);
    }

    public Socket createSocket(String arg0, int arg1, InetAddress arg2, int arg3) throws IOException, UnknownHostException {
        return trustedFactory.createSocket(arg0, arg1, arg2, arg3);
    }

    public Socket createSocket(InetAddress arg0, int arg1, InetAddress arg2, int arg3) throws IOException {
        return trustedFactory.createSocket(arg0, arg1, arg2, arg3);
    }
}

希望能够编译，我现在无法测试它！另请注意 initTrustedSSLSocketFactory 上的 throws 子句的惰性。

然后，当您设置 LDAP 环境时，请

TrustedSSLSocketFactory.initTrustedSSLSocketFactory(keyStore);
env.put("java.naming.ldap.factory.socket", TrustedSSLSocketFactory.class.getName())

按照与 Platinumsolutions 中的示例代码类似的方式使用。希望这正是您所寻找的？
