Warning: no suitable certificate found - continuing without client authentication


Team I am facing following issue when try to complete a mutual handshake using HTTPS

main, READ: TLSv1.2 Handshake, length = 30
*** CertificateRequest
Cert Types: RSA, DSS, ECDSA
Supported Signature Algorithms: SHA1withRSA, SHA1withDSA, SHA1withECDSA, SHA256withRSA, Unknown (hash:0x4, signature:0x2), SHA256withECDSA, SHA384withRSA, Unknown (hash:0x5, signature:0x2), SHA384withECDSA
Cert Authorities:
main, READ: TLSv1.2 Handshake, length = 4
*** ServerHelloDone
Warning: no suitable certificate found - continuing without client authentication
*** Certificate chain

My JAVA class is a follows

public class ClientCustomSSL {

    public final static void main(String[] args) throws Exception {
        // Trust own CA and all self-signed certs
        final String CLIENT_KEYSTORE = "yourkeystore.jks";
        final String CLIENT_TRUSTSTORE = "catruststore.jks";
        final char[] KEYPASS_AND_STOREPASS_VALUE = "Hello1".toCharArray();

        System.setProperty("https.protocols", "TLSv1");

        //SSLContext sslcontext = SSLContexts.custom().loadKeyMaterial(keystore, keyPassword)(YK,"Hello1".toCharArray(),"Hello1".toCharArray()).loadTrustMaterial(CA, "Hello1".toCharArray(), (TrustStrategy) new TrustSelfSignedStrategy()).build();

        KeyStore clientTrustStore = getStore(CLIENT_TRUSTSTORE, KEYPASS_AND_STOREPASS_VALUE);
        KeyStore clientKeyStore = getStore(CLIENT_KEYSTORE, KEYPASS_AND_STOREPASS_VALUE);  

        SSLContext sslContext = SSLContexts.custom().loadKeyMaterial(clientKeyStore, "Hello1".toCharArray()).loadTrustMaterial(clientTrustStore,(TrustStrategy) new TrustSelfSignedStrategy()).build();
       CloseableHttpClient httpclient = HttpClients.custom().setSSLContext(sslContext).build();

        System.out.println("SSLCONETXT   **** "   sslContext.getProvider());
        try {

            HttpGet httpget = new HttpGet("https://myserver:10220");

            CloseableHttpResponse response = httpclient.execute(httpget);

            try {
                System.out.println("Inside TRY blcok"); 
                HttpEntity entity = response.getEntity();

            } catch (Exception e) {
            finally {
        } finally {

    public static KeyStore getStore(final String storeFileName, final char[] password) throws KeyStoreException, IOException, CertificateException, NoSuchAlgorithmException 
        final String JAVA_KEYSTORE = "jks";
        final KeyStore store = KeyStore.getInstance(JAVA_KEYSTORE);
        URL url = ClientCustomSSL.class.getClassLoader().getResource(storeFileName);
        String workingDir = System.getProperty("user.dir");
        System.out.println("Current working directory : "   workingDir);

        System.out.println("Value of URL *** "   url);
        InputStream inputStream = url.openStream();
        try {
            store.load(inputStream, password);
} finally {

return store;


I am preparing a jar file and testing this from UNIX box

Using following command java -Djavax.net.debug=ssl -cp snSSLclientTrustWithStoreCCC.jar cassandra.cass.ClientCustomSSL

I have followed post why doesn't java send the client certificate during SSL handshake? and also completed all the steps mentioned by Bruno.

I am not sure what I am missing here. Any help will be appreciated

  1. The client was unable to find a certificate in its keystore that was signed directly or indirectly by any of the signers mentioned in the CertificateRequest message.
  2. The reason for that was that the server didn't specify any trusted signers in that message.
  3. Which in turn means that the server's truststore is empty.
