Hi dev-crypto:
I recently has a project that needs to support TSLv1.2 with JDK1.6_45. We need to \
connection to one of the third party server which, will be using TSLv1.2 only, and \
updating JDK is not an option for us yet. Then I starts to search the web find some \
examples about BouncyCastle, and complete my first draft implementation. However, \
when I run it, I got an exception as follow:
Exception in thread "main" java.io.IOException: Internal TLS error, this could be an \
attack
at org.bouncycastle.crypto.tls.TlsProtocol.failWithError(TlsProtocol.java:879)
at org.bouncycastle.crypto.tls.TlsProtocol.safeReadRecord(TlsProtocol.java:530)
at org.bouncycastle.crypto.tls.TlsProtocol.readApplicationData(TlsProtocol.java:498)
at org.bouncycastle.crypto.tls.TlsInputStream.read(TlsInputStream.java:29)
Then I search around in google, and find an simple sample, when I run it, I got the \
same exception. The sample is basically make a ssl connection to \
www.google.com<http://www.google.com>:443. Below is code:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;
import org.bouncycastle.crypto.tls.CertificateRequest;
import org.bouncycastle.crypto.tls.DefaultTlsClient;
import org.bouncycastle.crypto.tls.TlsAuthentication;
import org.bouncycastle.crypto.tls.TlsClientProtocol;
import org.bouncycastle.crypto.tls.TlsCredentials;
public class BouncyCastleTest {
public static void main(String[] args) throws Exception {
java.security.SecureRandom secureRandom = new java.security.SecureRandom();
Socket socket = new \
Socket(java.net.InetAddress.getByName("www.google.com<http://www.google.com>"), \
443);
TlsClientProtocol protocol = new TlsClientProtocol(socket.getInputStream(), \
socket.getOutputStream(),secureRandom); DefaultTlsClient client = new \
DefaultTlsClient() {
public TlsAuthentication getAuthentication() throws IOException {
TlsAuthentication auth = new TlsAuthentication() {
// Capture the server certificate information!
public void \
notifyServerCertificate(org.bouncycastle.crypto.tls.Certificate serverCertificate) \
throws IOException { }
public TlsCredentials getClientCredentials(CertificateRequest \
certificateRequest) throws IOException { return null;
}
};
return auth;
}
};
protocol.connect(client);
java.io.OutputStream output = protocol.getOutputStream();
output.write("GET / HTTP/1.1\r\n".getBytes("UTF-8"));
output.write("Host: \
www.google.com\r\n".getBytes("UTF-8"))<http://www.google.com/r/n%22.getBytes(%22UTF-8%22))>;
output.write("Connection: close\r\n".getBytes("UTF-8")); // So the server \
will close socket immediately.
output.write("\r\n".getBytes("UTF-8")); // HTTP1.1 requirement: last line \
must be empty line. output.flush();
java.io.InputStream input = protocol.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
String line;
while ((line = reader.readLine()) != null)
{
System.out.println(line);
}
try {
if (socket != null) {
socket.close();
}
if (output != null) {
output.close();
}
if (input != null) {
input.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
** copy mostly from http://stackoverflow.com/questions/18065170/how-do-i-do-tls-with-bouncycastle
When I run this sample, more than half of the page being outputted, but at last, it \
throws the above error at the end. However, if I change the header to connection: \
keep-alive, as below output.write("Connection: keep-alive\r\n".getBytes("UTF-8"));
Then I can see the whole page from google with no problem, only the read.readline() \
will never returns (because the connection is active). What I am guessing is \
somewhere is not considering the steam has been closed by the server? I then download \
the debug version of the jar bcprov-debug-jdk15on-154.jar and run this again. And \
find out org.bouncycastle.crypto.tos.RecordStream.readRecord() line 140, the method \
readRecord() return false when TlsUtils.readAllOrNothing return null (I am guessing \
null is expected as the connection has been close?). When readRecord() return false, \
org.bouncycastle.crypto.tls.TlsProtocal.safeReadRecord() throws an EOFException, and \
pass the exception to failWithError, which then, throw the IOException with message \
showing on the above error.
Sorry about the lengthen email, as I am just trying to give as much as information I \
can find. Can anyone please take a look the above error?
Thank you very much, any help is greatly appreciated!
