我知道这个主题在很多地方都有讨论,但在我经历了几乎所有这些之后,我决定创建我的第一个StackOverflow问题......
问题如下:
我想连接到使用证书来限制访问的安全Web服务(https),以及用于验证用户身份的用户名/密码。所以我有一个客户端证书(p12文件)和一个服务器证书(pem或der文件)。我尝试使用HttpURLConnection类,因为从我所听到的,Android上将不再支持Apache库。
所以这是我的实现(serverCert和clientCert是我文件的完整路径):
// Load CAs from our reference to the file
CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream caInput = new BufferedInputStream(new FileInputStream(serverCert));
X509Certificate serverCertificate;
try {
serverCertificate = (X509Certificate)cf.generateCertificate(caInput);
System.out.println("ca=" + serverCertificate.getSubjectDN());
} finally {
caInput.close();
}
Log.d(TAG, "Server Cert: " + serverCertificate);
// Create a KeyStore containing our trusted CAs
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null);
trustStore.setCertificateEntry("my ca", serverCertificate);
//Load the Client certificate in the keystore
KeyStore keyStore = KeyStore.getInstance("PKCS12");
FileInputStream fis = new FileInputStream(clientCert);
keyStore.load(fis,CLIENT_PASSWORD);
// Create a TrustManager that trusts the CAs in our KeyStore
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(trustStore);
//Build the SSL Context
KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(keyStore, pref.getString(Constants.clientCertificatePassword, "").toCharArray
());
//Create the SSL context
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
...
//And later, we use that sslContext to initiatize the socketFactory
urlConnection = (HttpsURLConnection) requestedUrl.openConnection();
urlConnection.setSSLSocketFactory(CertificateManager.getInstance().getSslContext().getSocketFactory());
...
所以我可以创建我的SSLContext,并显示我的两个证书内容。但是当我尝试执行我的HTTPS连接时,我得到以下异常:
09-23 13:43:30.283:W / System.err(19422):javax.net.ssl.SSLHandshakeException:java.security.cert.CertPathValidatorException:找不到证书路径的信任锚。
你们其中一个人是否遇到过以下错误?你的解决方案是什么?
这些是我经历的网站(没有成功):

答案 0 :(得分:1)
在您的代码中,您正在创建并初始化SSLContext
但不使用它。也许你应该替换:
urlConnection.setSSLSocketFactory(CertificateManager.getInstance().getSslContext().getSocketFactory());
通过
urlConnection.setSSLSocketFactory(sslContext.getSocketFactory());
我还建议您尽可能将选项-Djavax.net.debug=all
传递给JVM。它将在标准输出上打印有关SSL连接和握手的详细信息。
