问题
In my android application i connect over https. I am using a self signed certificate to connect. It is working on devices below api level 24 (before android nougat).But on android Nougat it throws the SSL Handshake exception :
javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
This is how i connect over https:-
SSLContext context = null;
try
{
KeyStore keyStore = KeyStore.getInstance("PKCS12");
// Get the raw resource, which contains the keystore with
// your trusted certificates (root and any intermediate certs)
InputStream input = new BufferedInputStream(context.getAssets().open(pkcsFilename));
try {
// Initialize the keystore with the provided trusted certificates
// Also provide the password of the keystore
keyStore.load(input, password.toCharArray());
} finally {
input.close();
}
KeyManagerFactory keyFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyFactory.init(keyStore, "".toCharArray());
// Load CAs from an InputStream
// (could be from a resource or ByteArrayInputStream or ...)
CertificateFactory cf = CertificateFactory.getInstance("X.509");
Certificate ca = null;
input = new BufferedInputStream(context.getAssets().open(certificateFilename));
try
{
ca = cf.generateCertificate(input);
}
finally
{
input.close();
}
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
trustStore.setCertificateEntry("server", ca);
// Create a TrustManager that trusts the CAs in our KeyStore
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(trustStore);
// Create an SSLContext that uses our TrustManager
context = SSLContext.getInstance("TLS");
context.init(keyFactory.getKeyManagers(), tmf.getTrustManagers(), null);
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
I tried the following link, But it does not help.
This is my network config file. I have added it in my AndroidManifest.xml file.
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config>
<domain includeSubdomains="true">xyz.com</domain>
<trust-anchors>
<certificates src="@raw/root_ca" />
</trust-anchors>
</domain-config>
</network-security-config>
Please help me how to solve this .
回答1:
System.setProperty("javax.net.ssl.trustStore",newKeystoreFile.getAbsolutePath());
simliarly, try to set keystorepassword and keypassword property restart the server each time whenever you are trying to use above property https://docs.oracle.com/cd/E17802_01/webservices/webservices/reference/tutorials/wsit/doc/WSIT_Security6.html

i got it working by adding a custom trust managers. While initializing the SSL Context context.init(keyFactory.getKeyManagers(), tmf.getTrustManagers(), null);
I modified it as :
context.init(keyFactory.getKeyManagers(), new TrustManager[] { tm }, null);
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
for (int j=0; j<chain.length; j++)
{
chain[j].checkValidity();
try {
chain[j].verify(ca.getPublicKey());
} catch (NoSuchAlgorithmException | InvalidKeyException | NoSuchProviderException |
SignatureException e) {
e.printStackTrace();
throw new CertificateException(e.getMessage());
}
}
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
i verify the certificate with the server certificate . Now its working .
