我知道这个主题在很多地方都被讨论过,但是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),并使用用户名/密码对用户进行身份验证。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,因为据我所知,Android 将不再支持 Apache 库。
所以这是我的实现(serverCert 和 clientCert 是我的文件的完整路径):
// 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 HTTPS 连接时,出现以下异常:
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。
你们中有人遇到过以下错误吗?你的解决方案是什么?
这些是我浏览的网站(没有成功):
