Unsupported key type: Sun DSA Public Key

Hi all,
Does anyone know how to use the SHA1withDSA algorithm with WSS4J/Axis?
When using a private key generated by keytool with type DSA, I get the errors:
org.apache.ws.security.WSSecurityException: Cannot encrypt data
Caused by: java.security.InvalidKeyException: Unsupported key type: Sun DSA Public Key
It seems I have to generate the key using type RSA.
Regards,
Alex

DSA (Digital Signature Algorithm) keys, by definition, can only be used for digital signature and not for encryption. As EJP suggested, you must use the RSA key-type and the SHA1withRSA - I would recommend using SHA256withRSA - construct to enable message-confidentiality.

Invalid Key Exception: Unsupported key type: Sun RSA public key, 1024 bits

I am trying to retrieve certificates from Microsoft Keystore and extract its keys using SunMSCAPI in jdk 1.6. It gives me an invalid key exception, when I am trying to wrap the Symmetric key (which was previously used to perform AES encryption on data), using RSA algorithm.
Code snippet:
           // RSA 1024 bits Asymmetric encryption of Symmetric AES key
            // List the certificates from Microsoft KeyStore using SunMSCAPI.
                  System.out.println("List of certificates found in Microsoft Personal Keystore:");
                   KeyStore ks = KeyStore.getInstance("Windows-MY", "SunMSCAPI");
                   ks.load(null, null) ;
                   Enumeration en = ks.aliases() ;
                   PublicKey RSAPubKey = null;
                   Key RSAPrivKey = null;
                   int i = 0;
                   while (en.hasMoreElements()) {
                        String aliasKey = (String)en.nextElement() ;
                        X509Certificate c = (X509Certificate) ks.getCertificate(aliasKey) ;
                        String sss = ks.getCertificateAlias(c);
                        if(sss.equals("C5151997"))
                        System.out.println("---> alias : " + sss) ;

                   rsaCipher.init(Cipher.WRAP_MODE, RSAPubKey);
                   byte[] encryptedSymmKey = rsaCipher.wrap(aeskey);

Added [ code] tags to make code readable.

A bit of research indicates that the classes of the keys obtained by
                      RSAPubKey = c.getPublicKey();
                           RSAPrivKey = ks.getKey(aliasKey, null); //"mypassword".toCharArray()are sun.security.rsa.RSAPublicKeyImpl and sun.security.*mscapi*.RSAPrivateKey . It seems that for Cipher objects from the SunMSCAPI provider cannot accept RSA public keys of class sun.security.rsa.RSAPublicKeyImpl and that the SunMSCAPI will only accept RSA private keys of class sun.security.mscapi.RSAPrivateKey.
This came up under different guise a couple of years ago. It makes sense since encrypting/wrapping with a public key does not represent a security problem (there is nothing secret in any of the encryption operations) when done outside of MSCAPI so one can use any provider that has the capability BUT the decryption/unwrapping must be done with the SunMSCAPI provider which delegates it to the MSCAPI.
My working test code based on your code implementing this approach is :
        // RSA 1024 bits Asymmetric encryption of Symmetric AES key
        // List the certificates from Microsoft KeyStore using SunMSCAPI.
        System.out.println("List of certificates found in Microsoft Personal Keystore:");
        KeyStore ks = KeyStore.getInstance("Windows-MY", "SunMSCAPI");
        ks.load(null, null);
        Enumeration en = ks.aliases();
        PublicKey RSAPubKey = null;
        Key RSAPrivKey = null;
        int i = 0;
        while (en.hasMoreElements())
            String aliasKey = (String) en.nextElement();
            X509Certificate c = (X509Certificate) ks.getCertificate(aliasKey);
            String sss = ks.getCertificateAlias(c);
            if (sss.equals("rsa_key")) // The alias for my key - make sure you change it back to your alias
                System.out.println("---> alias : " + sss);
                i = i + 1;
                String str = c.toString();
                System.out.println(" Certificate details : " + str);
                RSAPubKey = c.getPublicKey();
         System.out.println(RSAPubKey.getClass().getName());
               RSAPrivKey = ks.getKey(aliasKey, null); //"mypassword".toCharArray()

Please help I am stuck at "not a DSA public key"

Hi
I am just starting with the certificate/security API so this may be a naive question. I have a certificate,private key signature & data from a third-party. I am using following program to verify the signature.
import java.io.*;
import java.security.*;
import java.security.cert.CertificateFactory;
import java.security.cert.X509Certificate;
import java.security.spec.*;
import java.util.Collection;
import java.util.Iterator;
class VerSig {
    public static void main(String[] args) {
        /* Verify a DSA signature */
        if (args.length != 3) {
            System.out.println("Usage: VerSig publickeyfile signaturefile datafile");
        else try{
            InputStream inStream = new FileInputStream(args[0]);
            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            Collection c = cf.generateCertificates(inStream);
            Iterator i = c.iterator();
            X509Certificate cert = null;
            while (i.hasNext()) {
                cert = (X509Certificate)i.next();
            inStream.close();
            PublicKey pubKey = null;
            if (cert != null)
                pubKey = cert.getPublicKey();
            // create a Signature object and initialize it with the public key
            Signature sig = Signature.getInstance("SHA1withDSA","SUN");
            sig.initVerify(pubKey);
            // Update and verify the data
            FileInputStream datafis = new FileInputStream(args[2]);
            BufferedInputStream bufin = new BufferedInputStream(datafis);
            byte[] buffer = new byte[1024];
            int len;
            while (bufin.available() != 0) {
                len = bufin.read(buffer);
                sig.update(buffer, 0, len);
            bufin.close();
            //input the signature bytes
            FileInputStream sigfis = new FileInputStream(args[1]);
            byte[] sigToVerify = new byte[sigfis.available()];
            sigfis.read(sigToVerify );
            sigfis.close();
            boolean verifies = sig.verify(sigToVerify);
            System.out.println("signature verifies: " + verifies);
        } catch (Exception e) {
            System.err.println("Caught exception " + e.toString());
} First of all :
1) I wrote "Signature sig = Signature.getInstance("SHA1withDSA","SUN");" because somewhere in the certificate, I saw Signature Algorithm: SHA1withDSA. Is this correct?
2)I am getting following exception after
Signature sig = Signature.getInstance("SHA1withDSA","SUN");"
sig.initVerify(pubKey);
Caught exception java.security.InvalidKeyException: not a DSA public key: algorithm = SHA1withDSA, params unparsed, unparsed keybits =

what am I doing wrong?

Hi,
I am getting the same issue using JDK 1.4.2 regarding the "not a DSA public key" error.
I also tried using Bouncy Castle instead, but also fail at the verify step (although with a slightly different error):
"java.security.NoSuchAlgorithmException: no such algorithm: SHA
1with1.3.14.3.2.27 for provider BC"
My initial attempt using the Sun classes looks very much like the original example above. My Bouncy Castle implementation looks like:
Provider bc = new BouncyCastleProvider();
Security.insertProviderAt( bc, 1 );
try
// read PKCS#7 data from input stream
CMSSignedData sig = new CMSSignedData( request.getInputStream() );
CertStore certs = sig.getCertificatesAndCRLs( "Collection", "BC" );
SignerInformationStore signers = sig.getSignerInfos();
Collection c = signers.getSigners();
Iterator it = c.iterator();
while (it.hasNext())
SignerInformation signer = (SignerInformation)it.next();
Collection certCollection = certs.getCertificates( signer.getSID() );
Iterator certIt = certCollection.iterator();
X509Certificate cert = (X509Certificate)certIt.next();
logger.debug( "Cert = " + cert );
logger.debug( "Cert Sig Alg = " + cert.getSigAlgName() );
logger.debug( "Pub Key Alg = " + cert.getPublicKey().getAlgorithm() );
if ( signer.verify( cert, "BC" ) )
logger.debug( "Verified!" );
else
logger.debug( "Not verified." );
catch( Exception e )
e.printStackTrace();
return e.getMessage();
and provides the following output:

When trying to attach my key, the 'Attach My Public Key' option is blanked out so I can't use it.

This is referring to 'Digitally Signing and Encrypting Messages'. When trying to send my key by email, the 'Attach My Public Key' option is blanked out so I can't use it. I have a work around but it is a bit of a nuisance.
Any ideas?
Many thanks
Kevin

How to find modulus(n) and public key exponent(e)Sor

I did the following code:
import java.security.*;
class keypair
public static void main(String args[])
try {
        KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA");
        keyGen.initialize(1024);
        KeyPair keypair = keyGen.genKeyPair();
        PrivateKey privateKey = keypair.getPrivate();
        PublicKey publicKey = keypair.getPublic();
        System.out.println(publicKey);
catch (java.security.NoSuchAlgorithmException e) {
}It produced the following output:
E:\java>java keypair
Sun RSA public key, 1024 bits
modulus: 104598424699919432698042124865237006532583108525971624656815039032375

How to parse modulus(n) and public exponent(e) from this output?
Similarly when i print private key, it produces the following output:

From this output how to parse n and d, where d is the secret exponent or decryption exponent? Thanks in advance. Apologies, for posting in this forum instead of cryptography forum.

P.S. Extract the public and private keys from the key pair, cast them to RSAPublicKey and RSAPrivateKey as appropriate then look at the methods of classes RSAPublicKey and RSAPrivateKey to see how to get modulus and exponents.

Hello Nivas,
Public Key + Private Key "must pair together to be able to encrypt/decrypt
Private Key used to decrypt the message.
Public Key : used to encrypt the message, distributed freely to everyone
Private Key : kept secret on the machine so that only the owner can decrypt
the message, used to decrypt his public friends encrypted message.
You will find more details at :

Using Public key

Hi,
I really apologize for posting this thread which does not belong to this forum but I know someone must have use this in their shell scripting.
I have to use PUBLIC KEY in my shell script for connecting one server. How do I accomplish this.
Thanks for great help.

Is there any source code??
I can gererate public\private key but i want to decrypt the plain text using a public key .
Is there any way to generate a secret key "AES" from the public key??
Regards

Java.security.InvalidKeyException: Unsupported key type: SunPKCS11-MyPKCS11

I am having a very strange issue with my CAC card. I wrote a small Java program to login into ProjectForge.mil webservice
ICollabNetSoap m_sfSoap = (ICollabNetSoap)
ClientSoapStubFactory.getSoapStub(ICollabNetSoap.class, "https://project.forge.mil/");
String sessionId = m_sfSoap.login("", "");
After entering CAC PIN, it is throwing exception saying that "javax.net.ssl.SSLHandshakeException: Received fatal alert: unsupported_certificate".
More specific exception is:
Caused by: java.security.InvalidKeyException: Unsupported key type: SunPKCS11-MyPKCS11 RSA private key, 2048 bits (id 39632224, token object, sensitive, unextractable)
Note: I have asked three of my co-workers to run the same program using their CAC's and seems to be working fine.
Only the difference between their CACs and mine is CA(Certificate Authority Value. Their's is 24 and where as mine is 25). It looks like JVM was not able to understand the private key of my CAC.
On the other note, my CAC cworks fine with web service client application that was written in .Net.
I am using Jdk-1.6.0_26 and I have already downloaded and installed latest jce .jar files.
Any help is greatly appreciated
Here are the exception details:

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.
Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?
If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, 8007000B.)

I have taken all apple products off my computer per other suggestions, I have run malwarebytes with no viruses found, and have even tried installing itunes as a different user on my computer but get the same message everytime.
