We can create XML Digital Signature using RSA keys. But how do I use elliptic curve keys to sign xml files ? I get exception at this line xmlSignature.sign(domSignCtx) as -

I am trying to add digital signature to the existing xml document. I am reading private key and public key from .pem file. And I can generate and verify same for SignatureMethod.RSA_SHA256. But for ECDSA_SHA256 I am getting Invalid ECParameterSpec exception. Please suggest how to generate XML Signature for secp256k1 curve using SHA256WithECDSA algorithm in java.

I implemented a custom key manager, in order to choose which alias use when i need a ssl handshake.
The problem is that none of the methods of my custom key manager gets called, although it's correctly instantiated.
With a keystore containing just ONE alias, communication is fine and the code works, but the aim here is to have the possibility to change aliases during runtime.
Here is the full code of my implementation. Any Help is appreciated.
package ssl;
import java.net.Socket;
import java.security.Principal;
import java.security.PrivateKey;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLEngine;
import javax.net.ssl.X509ExtendedKeyManager;
import javax.net.ssl.X509KeyManager;
public class AliasSelectorKeyManager extends X509ExtendedKeyManager {
private X509KeyManager sourceKeyManager = null;
private String alias;
public AliasSelectorKeyManager(X509KeyManager keyManager, String alias) {
this.sourceKeyManager = keyManager;
this.alias = alias;
}
#Override
public String chooseEngineClientAlias(String[] paramArrayOfString, Principal[] paramArrayOfPrincipal, SSLEngine paramSSLEngine) {
return chooseClientAlias(paramArrayOfString, paramArrayOfPrincipal, null);
}
#Override
public String chooseClientAlias(String[] keyType, Principal[] issuers, Socket socket) {
boolean aliasFound = false;
//Get all aliases from the key manager. If any matches with the managed alias,
//then return it.
//If the alias has not been found, return null (and let the API to handle it,
//causing the handshake to fail).
for (int i = 0; i < keyType.length && !aliasFound; i++) {
String[] validAliases = sourceKeyManager.getClientAliases(keyType[i], issuers);
if (validAliases != null) {
for (int j = 0; j < validAliases.length && !aliasFound; j++) {
if (validAliases[j].equals(alias)) {
aliasFound = true;
}
}
}
}
if (aliasFound) {
return alias;
} else {
return null;
}
}
}
All this does is simply override each method calling the specific sourceKeyManager implementation. The customization comes into the two methods:
chooseEngineClientAlias;
chooseClientAlias

Has the needClientAuth flag been turned on the server side?
https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLEngine.html#setNeedClientAuth(boolean)
The server asks the client’s authentication during the handshake only if the flag is turned on.
I am currently developing a SOAP-Server/Client using CXF rev 3.1.10.
Everything is set up and works quite fine as long as I don't try to use https.
I am not using any xml-files/beans, except the ones that might be used 'behind the scenes' by the framework.
I would actually like to leave it that way.
I am using a self signed certificate and its extracted keys, just in case this might be necessary.

The Client is siarting up as well , however, the moment the client tries to retrieve the WSDL and/or tries to execute any of its methods i get:
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
...
As I previously mentioned, everything works fine as long as I use http instead of https.
I don't think that the problem are the keystores as I can finally read them and get their keys by using e.g.
private static void displayKeys(String ksForm, String alias, char[] ksPass, char[] kePass, String keystore) throws Exception {
System.out
.println("---------------------------------------------------------------------------------------------------------------------------");
KeyStore keyStore = KeyStore.getInstance(ksForm);
keyStore.load(new FileInputStream(keystore), ksPass);
Key key = keyStore.getKey(alias, kePass);
if (key instanceof PrivateKey) {
System.out.println("Get private key : ");
System.out.println(key.toString());
java.security.cert.Certificate[] certs = keyStore.getCertificateChain(alias);
System.out.println("Certificate chain length : " + certs.length);
for (Certificate cert : certs) {
System.out.println(cert.toString());
}
} else {
System.out.println("Get public key : ");
System.out.println(key.toString());
}
System.out
.println("---------------------------------------------------------------------------------------------------------------------------");
}
Caused by: java.io.EOFException: SSL peer shut down incorrectly
Thanks in advance and kind regards.
So, I was finally able to figure it out.
Actually there were several Problems at hand
The created keystore itself was fine, the extracted (for client use) cert wasn't
Loading keystore and truststore in both, server and client, was a huge mistake, especially since I've used the same store/certs for both (for this I think WSS4J Interceptors and CallBackHandlers are necessary)
During several trial and error periods I also seems to have mixed up entry and store password.
Below I will give you the code for all the classes that I've used to get a fully running example.
Key And Cert Generation
As I always had problems with the SunAPI and its code examples for certificate creation I decided to use BouncyCastle instead.
Even though I previously decided to not use a 3rd party tool, I changed my mind due to the fact that I use this only for keystore/cert creation.
The class you are about to see is a slightly modified version of the answer from 'Maarten Bodewes' to this question:
How to store and reuse keypair in Java?
The class is pretty straight forward, hence no method comments were added...

Thanks to everyone who read my question and thought of a possible solution.
Hopefully this can help others .
Kind regards
I'm trying to write gpg encryptor/decryptor (code below). In first step program encrypts "#data1\n#data2\n#data3\n" string and in next step decrypts the array of bytes that decryptor returns. But... why text from decryptor is not the same as "#data1\n#data2\n#data3\n" ? Where did I missed something ? Thanks for your help.

They aren't the same because you are base-64 encoding the results of the decryption, rather than decoding it as text. Do this instead:
byte[] decData = decryptData(cipher, privKey, encData);
System.out.println("\n\nDecrypted data=" + new String(decData));
It is poor practice to use the platform default character encoding. Instead, you should convert text to bytes with with specific encoding, and use the same coding when decoding the bytes.
byte[] plaintext = "#data1\n#data2\n#data3\n").getBytes(StandardCharsets.UTF_8);
...
String recovered = new String(decData, StandardCharsets.UTF_8);
