Android通过SSL与Bouncy Castle进行服务器之间的通信

Question

我知道这并不是一件容易的事，但是很遗憾，自昨天以来我一直被困在这里并与之抗争。我遵循了Android互助身份验证教程，将密钥库放置在资源中并尝试通过SSL连接到我的服务器，但是得到以下异常

java.lang.RuntimeException：org.spongycastle.jcajce.provider.asymmetric.x509.CertificateFactory
$ ExCertificateException

我将sslapptruststore.pfx文件放在下面res/raw/sslapptruststore.pfx 并使用了这段代码

try {

                           KeyStore clientCert = KeyStore.getInstance("PKCS12");
                                   clientCert.load(getResources().openRawResource(R.raw.sslapptruststore), "123456".toCharArray());// this line causes exception

                            HttpClient httpClient = null;
                            HttpParams httpParams = new BasicHttpParams();
                            SSLSocketFactory sslSocketFactory = new SSLSocketFactory(clientCert, null, null);
                            SchemeRegistry registry = new SchemeRegistry();
                            registry.register(new Scheme("https", sslSocketFactory, 8443));
                            httpClient = new DefaultHttpClient(new ThreadSafeClientConnManager(httpParams, registry), httpParams);


                            HttpPost httpPost = new HttpPost(
                                    "https://192.168.1.113:8443/CertProvider");
                            httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
                            List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
                            nameValuePair.add(new BasicNameValuePair("csr", csr.toString()));

                            // Url Encoding the POST parameters
                                httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));

                            // Making HTTP Request
                            // HttpResponse response = null;
                            ResponseHandler<String> responseHandler = new BasicResponseHandler();
                            String response = "";
                            response = httpClient.execute(httpPost, responseHandler);
                                } catch (Exception e) {
                                    Log.e("", e.getMessage());
                                }

我也搜索过，但其他人正在使用.bks。

任何帮助表示赞赏。
