data 52e - Returns when username is valid but password/credential is invalid.
I am guessing that you are passing the password to Microsoft Active Directory in plain text which usually will not work.
We have a "updateUserPassword" method in our "JNDI Examples" repository that should help.

Bouncy castle gives unknown HashAlgorithm

I am trying to use bouncy castle for DTLS Handshake.
I have generated key by following this link. I am working by extending DefaultTlsClient. It can generate client_hello packet. But when the server_hello packet arrives it gives org.bouncycastle.crypto.tls.TlsFatalAlert: internal_error(80) Caused by: java.lang.IllegalArgumentException: unknown HashAlgorithm. Can anyone give any hint?
Update:
From Wireshark: In the Certificate Request, there are 9 Signature Hash Algorithms. One of them is rsa_pss_sha256(0x0804). In the public static Digest createHash(short hashAlgorithm) function in TlsUtils.java there is no matching for it. That's why it is giving Unknown hash Algorithm. What does that mean? Using Bouncy Castle, is it possible to establish DTLS with that server?
Here is the code for loading the keystore:
public static void initKeyStore() {
char password[] = "bbtone".toCharArray();
if( !isKeystoreLoaded) {
try {
FileInputStream fis = new FileInputStream("bbtone");
KeyMgmt key = new KeyMgmt();
key.open(fis, password);
fis.close();
crt = key.getCRT("bbtone").getEncoded();
fingerprintSHA256 = KeyMgmt.fingerprintSHA256(crt);
ArrayList<byte[]> chain = new ArrayList<byte[]>();
chain.add(crt);
java.security.cert.Certificate root = key.getCRT("root");
if (root != null) {
chain.add(root.getEncoded());
}
privateKey = key.getKEY("bbtone", password).getEncoded();
initDTLS(chain, privateKey, false);
isKeystoreLoaded = true;
} catch(FileNotFoundException e) {
e.printStackTrace();
} catch(Exception e) {
e.printStackTrace();
}
}
}
Generating private key and certificate:
public static boolean initDTLS(java.util.List<byte []> certChain, byte privateKey[], boolean pkRSA) {
try {
org.bouncycastle.asn1.x509.Certificate x509certs[] = new org.bouncycastle.asn1.x509.Certificate[certChain.size()];
for (int i = 0; i < certChain.size(); ++i) {
x509certs[i] = org.bouncycastle.asn1.x509.Certificate.getInstance(certChain.get(i));
}
dtlsCertChain = new org.bouncycastle.crypto.tls.Certificate(x509certs);
if (pkRSA) {
RSAPrivateKey rsa = RSAPrivateKey.getInstance(privateKey);
dtlsPrivateKey = new RSAPrivateCrtKeyParameters(rsa.getModulus(), rsa.getPublicExponent(),
rsa.getPrivateExponent(), rsa.getPrime1(), rsa.getPrime2(), rsa.getExponent1(),

} else {

I have solved the problem using DTLS1.0. It can now finish the handshake.
I replaced
public ProtocolVersion getClientVersion() {
return ProtocolVersion.DTLSv12;
}
with the following code:
public ProtocolVersion getClientVersion() {
return ProtocolVersion.DTLSv10;
}

#Rashed, downgrading TLS version is not a good choice. There is already comment from #bbaldino but I think it should be added as answer - version 1.60 of bouncy castle has a bug. Instead of downgrading TLS, you should upgrade bouncy castle to at least 1.61

TLS 1.2 + Java 1.6 + BouncyCastle

For supporting HTTPS connections through a Java 1.6 API to remote hosts using TLS 1.2, we have developed a customized TLS SocketConnection factory based on Bouncy Castle Libraries (v. 1.53)
It's very easy to use, just:
String httpsURL = xxxxxxxxxx
URL myurl = new URL(httpsURL);
HttpsURLConnection con = (HttpsURLConnection )myurl.openConnection();
con.setSSLSocketFactory(new TSLSocketConnectionFactory());
InputStream ins = con.getInputStream();
During testing, I connect different web and remote hosts exposed into SSLabs Tests
90% of the time this works fine! But there are some cases in which we get an annoying error: "Internal TLS error, this could be an attack" . It has been checked that there is no attack. That's a common error based on the treatment of internal BouncyCastle exceptions. I'm trying to find a common pattern to those remote host that fails with little luck.
Updated:
Updating some code for extra information, we get this:
org.bouncycastle.crypto.tls.TlsFatalAlert: illegal_parameter(47)
at org.bouncycastle.crypto.tls.AbstractTlsClient.checkForUnexpectedServerExtension(AbstractTlsClient.java:56)
at org.bouncycastle.crypto.tls.AbstractTlsClient.processServerExtensions(AbstractTlsClient.java:207)
at org.bouncycastle.crypto.tls.TlsClientProtocol.receiveServerHelloMessage(TlsClientProtocol.java:773)
The extension type i get is this:
ExtensionType:11
ExtensionData:
Acording to ExtensionType class, "ec_point_formats". This causes "UnexpectedServerExtension" --> The "UnexpectedServerExtension" causes a --> TlsFatalAlert: illegal_parameter , and at last this a "Internal TLS error, this could be an attack"
Any advise to log or trace this strange TLS Errors....???? As i say, this code works 90%...but with some remote host i get this errof
The trick consists in overriding startHandShake to use Bouncy's TLSClientProtocol:
Override ClientExtensions to include "host" ExtensionType. Just ExtensionType.server_name ( maybe any more Extension to include?)
Create a TlsAuthentication to include remoteCerts on Socket's
peerCertificate .Also optionally check if remote certs are in
default keystore (cacerts,etc..)

If you look at RFC 4492 5.2, you'll see that the server CAN send the "ec_point_formats" extension, but is only supposed to do so "when negotiating an ECC cipher suite". If you want TLSClient to just ignore the extra extension instead of raising an exception, I suggest overriding TlsClient.allowUnexpectedServerExtension(...) to allow ec_point_formats in the same way the default implementation allows elliptic_curves:
protected boolean allowUnexpectedServerExtension(Integer extensionType, byte[] extensionData)
throws IOException
{
switch (extensionType.intValue())
{
case ExtensionType.ec_point_formats:
/*
* Exception added based on field reports that some servers send Supported
* Point Format Extension even when not negotiating an ECC cipher suite.
* If present, we still require that it is a valid ECPointFormatList.
*/
TlsECCUtils.readSupportedPointFormatsExtension(extensionData);
return true;
default:
return super.allowUnexpectedServerExtension(extensionType, extensionData);
}
}
If this is a widespread problem, we might consider adding this case to the default implementation.
For logging, there are the (TLSPeer) methods notifyAlertRaised and notifyAlertReceived that you can override on your TLSClient implementation.

i am posting this so maybe some people might find this helpful - i was also getting invalid_parameter(47) exception from my BC client code.
this error started to happen when we upgraded BC from version 1.62 (bcprov- and bctls-jdk15on-162 JARs) to 1.71 (bcprov-, bctls-, bcpkix-, bcutil-jdk15to18-171).
my stacktrace was different from the above problem, though:
org.bouncycastle.tls.TlsFatalAlert: illegal_parameter(47)
at org.bouncycastle.tls.TlsClientProtocol.processServerHello(Unknown Source)
at org.bouncycastle.tls.TlsClientProtocol.handleHandshakeMessage(Unknown Source)

I had some trouble figuring out how to debug the internal BC TLS code. Тhe provided JARs are compiled without the debug info - I had to download the source files from Maven Central and build from them, creating a new project in Netbeans with existing sources - the only Java version it can be built with is 8, but the end result could be referenced by my Java 6 client code.
Having compiled bctls with debug info, and referencing it from my client, I could actually land in the code that was throwing the exception:
protected void processServerHello(ServerHello serverHello)
throws IOException
{
...
if (sessionServerExtensions != null && !sessionServerExtensions.isEmpty())
{
{
/*
* RFC 7366 3. If a server receives an encrypt-then-MAC request extension from a client
* and then selects a stream or Authenticated Encryption with Associated Data (AEAD)
* ciphersuite, it MUST NOT send an encrypt-then-MAC response extension back to the
* client.
*/
boolean serverSentEncryptThenMAC = TlsExtensionsUtils.hasEncryptThenMACExtension(sessionServerExtensions);
if (serverSentEncryptThenMAC && !TlsUtils.isBlockCipherSuite(securityParameters.getCipherSuite()))
{
throw new TlsFatalAlert(AlertDescription.illegal_parameter);
}
securityParameters.encryptThenMAC = serverSentEncryptThenMAC;
}
...
}
I don't really know what encrypt-then-MAC and MAC-then-encrypt is, and I didn't want to get deep into their meaning. After some searching, I figured out that possibly I had to limit the list of the cipher suites used for the communication - because possibly some cipher suite that is chosen by default forces the server into some condition where it behaves differently from the RFC specification - and yes, this at least worked:
TrustManagerFactory tmf = ...
SSLContext sc = SSLContext.getInstance("TLSv1.2", BouncyCastleJsseProvider.PROVIDER_NAME);
sc.init(null, tmf.getTrustManagers(), new SecureRandom());
SSLConnectionSocketFactory ret = new SSLConnectionSocketFactory(sc,
new String[] { "TLSv1.2" },
new String[] { "TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384", "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384", "TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256", "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256",
"TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384", "TLS_DHE_DSS_WITH_AES_256_GCM_SHA384", "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256", "TLS_DHE_DSS_WITH_AES_128_GCM_SHA256" },
SSLConnectionSocketFactory.getDefaultHostnameVerifier());
// the created SSLConnectionSocketFactory is then used to create socketFactoryRegistry
// which is then passed to constructor of Apache HttpComponents' PoolingHttpClientConnectionManager
// which is used to create a new instance of Apache HttpClient
Other useful stuff that I learned is
there are sites, e.g. https://www.ssllabs.com/ssltest that analyze the available protocols and cipher suites that a server supports.
the list of the cipher suites above is not exactly arbitrary - I took it from this stackoverflow q&a.

SocketTimeoutException cxf httpconduit PUT

I have a test that takes a lot of time and ended up making a timeout.
I tried the solution bob and nothing it does not work.
The error occurs just on tests PUT.
My Test :
#Test
public void testUpdateUse(){
setExpectedResponse("{\"id\":1,\"username\":\"test\",\"email\":\"bob#test.ca\"}");
User userToUpdate = new User();
userToUpdate.setEmail("bob#test.ca");
userToUpdate.setUsername("superbob");
userToUpdate.setId(1);
UserOrganization userOrganization = new UserOrganization();
userOrganization.setOrganizationId(1);
List<UserOrganization> userOrganizations = new ArrayList<>();
userOrganizations.add(userOrganization);
UserOrganizationUnit userOrganizationUnit = new UserOrganizationUnit();
userOrganizationUnit.setOrganizationUnitId(1);
List<UserOrganizationUnit> userOrganizationUnits = new ArrayList<>();
userOrganizationUnits.add(userOrganizationUnit);
userToUpdate.setOrganizations(userOrganizations);
userToUpdate.setOrganizationUnits(userOrganizationUnits);
userAPIService.update(1, userToUpdate);
assertLatestRequest("PUT", "/users/1");
}
#Before
public void setUpServer() throws Exception {
Thread.sleep(500);
expectedResponse = null;
final Authenticator authenticator = new BasicAuthenticator("") {
#Override
public boolean checkCredentials(final String username, final String password) {
return getUsername().equals(username) && getPassword().equals(password);
}
};
final HttpHandler handler = new HttpHandler() {
#Override
public void handle(HttpExchange exchange) throws IOException {
final Authenticator.Result authResult = authenticator.authenticate(exchange);
if (authResult instanceof Authenticator.Success || !basicAuthRequired) {
latestExchange = exchange;
StringWriter writer = new StringWriter();
try {
IOUtils.copy(new InputStreamReader(latestExchange.getRequestBody()), writer, 1024);
} catch (IOException e) {
e.printStackTrace();
}
latestRequestBody = writer.toString();
byte[] response = expectedResponse.getBytes();
exchange.getResponseHeaders().add("Content-type", expectedContentType);
exchange.sendResponseHeaders(expectedStatus, response.length);
exchange.getResponseBody().write(response);
}
exchange.close();
expectedResponse = null;
}
};
httpServer = HttpServer.create(new InetSocketAddress(testPort), 0);
httpServer.createContext("/", handler);
httpServer.start();
}
#After
public void tearDownServer() throws Exception {
if (httpServer != null) {
httpServer.stop(0);
}
context.assertIsSatisfied();
Thread.sleep(500);
}
example code on applicationContext.xml:
<http:conduit name="{http://service.clientapi.user.com/}*.http-conduit">
<http:client CacheControl="no-store" Connection="Keep-Alive" AllowChunking="false" ConnectionTimeout="10000" ReceiveTimeout="60000"/>
</http:conduit>
Version CXF : 2.7.3
Version Spring 3
Java 7

My solution was to override the httpconduit in my test context.xml
<http:conduit name="*.http-conduit">
<http:client CacheControl="no-store" Connection="Keep-Alive" AllowChunking="false" ConnectionTimeout="10000" ReceiveTimeout="60000"/>
</http:conduit>

When I try to convert a string with certificate, Exception is raised

I have an applet which signes document, and sends a document, sign, and certificate to the server side. On the server side portlet receives these 3 files, all files are stored in base64 format, but when I try to get certificate it raises exception
java.security.cert.CertificateException: Could not parse certificate: java.io.IOException: Empty input
at sun.security.provider.X509Factory.engineGenerateCertificate(X509Factory.java:104)
applet side code:
public static byte[] certificate;
public static String getCertificateString() {
String str = "";
byte[] result = null;
result = Base64.encode(certificate);
for (int i = 0; i < result.length; i++) {
str += (char) (result[i]);
}
return str;
}
//initialization of certificate from the store
Certificate cert = store.getCertificate(aliasKey);
certificate = cert.toString().getBytes();
after this I send certificate to the portlet, where need to verify the sign. But the certificate conversion is failed.
portlet code:
String certificate = request.getParameter("cert");
byte[] cert_array = Base64.decode(certificate.getBytes());
try {
cert = CertificateFactory.getInstance("X509").generateCertificate(new ByteArrayInputStream(cert_array));
}catch(Exception e){
e.printStackTrace();
}
And at this point, in the try block, Exception is raised

Do NOT EVER trust all certificates. That is very dangerous. If you do that you may as well not use HTTPS and just use HTTP

Ok, #test1604 you try something like this, is implements X509TrustManager class, ok here we go:
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
public class YouNameClass implements X509TrustManager {...
public YouNameClass() {
super();
}
}
And add this method,
private static void trustAllHttpsCertificates() throws Exception {
// Create a trust manager that does not validate certificate chains:
javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[1];
javax.net.ssl.TrustManager tm = new YouNameClass();
trustAllCerts[0] = tm;
javax.net.ssl.SSLContext sc = javax.net.ssl.SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, null);
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
}
and methods override:
#Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
return;
}
#Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
return;
}
#Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
That's it. :)
