如何检索 SSL 客户端正在使用的 KeyManager、TrustManager 和 SecureRandom 对象？

Question

我正在尝试创建一个 SSL 套接字工厂，它使用 TSLv1.2 协议执行握手。

到目前为止我所拥有的[更新1/18]：

SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
ServerSocketFactory sf = SSLServerSocketFactory.getDefault();
KeyManager[] km = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm()).getKeyManagers();
TrustManager[] tm = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm()).getTrustManagers();
SecureRandom random = new SecureRandom();
sslContext.init(km, tm, random);
requestContext.put(BindingProviderProperties.SSL_SOCKET_FACTORY, sslContext.getSocketFactory());

我希望从 中获取 KeyManager、TrustManager 和 SecureRandom 对象SSLServerSocketFactory.getDefault()，但没有可用的 getter。
我可以从另一个地方提取这个吗？或者更有效的方法来做到这一点？

我不想手动创建密钥和信任管理器以避免需要系统特定的配置。

完整方法供参考：

    public MyOutBoundClientWSImpl(URL wsdlUrl){
        super(wsdlUrl, serviceName);
        this.wsUrl=wsdlUrl;
        this.mService = this.getMySoapHttpPort();
        Map<String, Object> requestContext = ((BindingProvider)mService).getRequestContext();
        requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, REQUEST_TIMEOUT); // Timeout in millis
        requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, CONNECT_TIMEOUT); // Timeout in millis
        try {
            SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
            ServerSocketFactory sf = SSLServerSocketFactory.getDefault();
            KeyManager[] km = ??;
            TrustManager[] tm = ??;
            SecureRandom random = ??;
            sslContext.init(km, tm, random);
            requestContext.put(BindingProviderProperties.SSL_SOCKET_FACTORY, sslContext.getSocketFactory());
        } catch (NoSuchAlgorithmException e) {
            throw new IllegalArgumentException(e.getMessage(), e);
        }
    }

查看官方文档：

https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLContext.html

public final void init(KeyManager[] km,
        TrustManager[] tm,
        SecureRandom random)
                throws KeyManagementException

初始化此上下文。前两个参数中的任何一个都可以为空，在这种情况下，将搜索已安装的安全提供程序以查找适当工厂的最高优先级实现。同样，安全随机参数可能为空，在这种情况下将使用默认实现。

事实证明这很容易做到，您只需将所有空值传递给 init 方法即可。

    public MyOutBoundClientWSImpl(URL wsdlUrl){
        super(wsdlUrl, serviceName);
        this.wsUrl=wsdlUrl;
        this.mService = this.getMySoapHttpPort();
        Map<String, Object> requestContext = ((BindingProvider)mService).getRequestContext();
        requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, REQUEST_TIMEOUT); // Timeout in millis
        requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, CONNECT_TIMEOUT); // Timeout in millis
        try {
            SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
            KeyManager[] km = null;
            TrustManager[] tm = null;
            SecureRandom random = null;                
            sslContext.init(km, tm, random);
            requestContext.put(BindingProviderProperties.SSL_SOCKET_FACTORY, sslContext.getSocketFactory());
        } catch (NoSuchAlgorithmException e) {
            throw new IllegalArgumentException(e.getMessage(), e);
        }
    }
