我有一个常规的Java应用程序，它使用以下代码连接到我的java服务器：
KeyStore ks = KeyStore.getInstance("JKS");
InputStream inputStream = getClass().getResourceAsStream("cert.jks");
ks.load(inputStream, "password".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(ks);
SSLContext ssc = SSLContext.getInstance("TLS");
ssc.init(null, tmf.getTrustManagers(), null);
SSLSocketFactory factory = ssc.getSocketFactory();
Socket socket = new Socket(Proxy.NO_PROXY);
InetAddress host = InetAddress.getByName("<ip address of server">);
int port = <some port>;
socket.connect(new InetSocketAddress(host, port));
SSLSocket ssls = (SSLSocket)factory.createSocket(socket, host.getHostAddress(), port, false);
ssls.setUseClientMode(true);
ssls.setNeedClientAuth(false);
ssls.startHandshake();
一切正常。但是，由于Android不支持JKS Keystores或SunX509，我必须进行一些更改。我已经使用充气城堡（帽子提示到：How to create a BKS (BouncyCastle) format Java Keystore that contains a client certificate chain）将JKS证书转换为BKS证书并使用了TrustManagerFactory的默认算法，所以现在我的代码如下所示：
KeyStore ks = KeyStore.getInstance("BKS");
android.content.res.Resources res = <getter for resources>;
InputStream inputStream = res.openRawResources(R.raw.cert); //The converted bks certificate stored in the raw directory
ks.load(inputStream, "password".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
SSLContext ssc = SSLContext.getInstance("TLS");
ssc.init(null, tmf.getTrustManagers(), null);
... same as above ...
ssls.startHandshake();
但是，上面的代码在startHandshake的最后一行抛出一个异常：
javax.net.ssl.SSLHandshakeException：com.android.org.conscrypt.OpenSSLSocketImpl.startHandshake（OpenSSLSocketImpl.java:324）中com.android.org.conscrypt.NativeCrypto.SSL_do_handshake（本地方法）的对等关闭连接
这里有什么问题？是否有任何其他信息可以提供帮助？
答案 0 :(得分：0)
InputStream inputStream = getClass().getResourceAsStream("cert.bks"); //The converted bks certificate
您应该将cert.bks文件放入/res/raw目录，然后使用getResources().openRawResource(R.raw.cert);打开该文件。
编辑：
我认为您在加载信任库时没有指定提供程序。
KeyStore keyStore = KeyStore.getInstance("BKS", BouncyCastleProvider.PROVIDER_NAME);
如果您忘记了，则需要在Application课程中添加SpongyCastle提供程序。
public class CustomApplication
extends Application {
static {
Security.insertProviderAt(new BouncyCastleProvider(), 1);
}
并将其添加到AndroidManifest.xml
<application
android:allowBackup="true"
android:name=".application.CustomApplication"
但如果仍然无效，您可以尝试做的是从Apache HttpClient的来源添加以下类（它的apache许可所以你可以这样做）：
import java.util.Collection;
class Args {
public static void check(final boolean expression, final String message) {
if (!expression) {
throw new IllegalArgumentException(message);

添加这些内容后，您可以像这样构建SSLContext：
SSLContextBuilder sslContextBuilder = SSLContextBuilder.create();
KeyStore keyStore = KeyStore.getInstance("BKS", BouncyCastleProvider.PROVIDER_NAME);
android.content.res.Resources res = <getter for resources>;
InputStream inputStream = res.openRawResources(R.raw.cert);
keyStore.load(inputStream, trustStorePassword);
sslContextBuilder.loadTrustMaterial(keyStore, trustStorePassword);
SSLContext sslContext = sslContextBuilder.build();
//okHttpClient.setSslSocketFactory(sslContext.getSocketFactory());
编辑：测试证书
keyStore.load(byteArrayInputStream, keyStorePassword);
Certificate[] certificates = keyStore.getCertificateChain("key-alias"); //you need to know the alias
if(certificates.length > 0) {
Certificate certificate = certificates[0];
X509Certificate x509Certificate = (X509Certificate) certificate;
Log.d(TAG,
"Certificate found with DN [" + x509Certificate.getSubjectDN() + "]");
答案 1 :(得分：0)
根据您的要求，您可以参考Google转换文档中的以下示例代码：
// Load CAs from an InputStream
// (could be from a resource or ByteArrayInputStream or ...)
CertificateFactory cf = CertificateFactory.getInstance("X.509");
// From https://www.washington.edu/itconnect/security/ca/load-der.crt
InputStream caInput = new BufferedInputStream(new FileInputStream("load-der.crt"));
Certificate ca;
try {
ca = cf.generateCertificate(caInput);
System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());
} finally {
caInput.close();
}
// Create a KeyStore containing our trusted CAs
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);
// Create a TrustManager that trusts the CAs in our KeyStore
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
// Create an SSLContext that uses our TrustManager
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
// Tell the URLConnection to use a SocketFactory from our SSLContext
URL url = new URL("https://certs.cac.washington.edu/CAtest/");
HttpsURLConnection urlConnection =
(HttpsURLConnection)url.openConnection();
urlConnection.setSSLSocketFactory(context.getSocketFactory());
InputStream in = urlConnection.getInputStream();
copyInputStreamToOutputStream(in, System.out);
