Problem with Sun PKCS#11 Provider and Ativcard smart card.

Question

Hi,
I'm trying to make a signature with a smartcard.
I have no problem signing with my card in applications such as Microsoft Office, Outlook (they probably use CAPICOM or MS CryptoAPI).
There is only one certificate on my card with non extractable pair of keys.
When I`m using Java based application I have the following problem:
I have Java 1.5.0 installed, and according to the reference guide on:
http://java.sun.com/j2se/1.5.0/docs/guide/security/p11guide.html
I configured "Sun PKCS#11 Provider".
In file:
%JAVA_HOME%/lib/security/java.security I inserted the following lines:
# Configuration for security providers 1..6 omitted
security.provider.7=sun.security.pkcs11.SunPKCS11 C:/pkcs11.cfg
In my case (I`m using ActivCard) The file "C:/pkcs11.cfg" contains:
name = ActivCard
library = c:\windows\system32\acpkcs211.dll
After that I try tu use configured provider with keytool.exe from jsdk.
In cmdline:
c:\Program Files\Java\jdk1.5.0_06\bin>keytool.exe -keystore NONE -storetype PKCS11 -list
Enter keystore password:  1111
Keystore type: PKCS11
Keystore provider: SunPKCS11-ActivCard
Your keystore contains 1 entry
Cinek's dp ID, keyEntry,
Certificate fingerprint (MD5): 36:19:DD:01:2E:A2:C5:F6:51:44:03:74:14:D5:62:C0
So till now everything looks ok. Certificate is accessible.
But when I trying to use jarsigner.exe to sign something:
c:\Program Files\Java\jdk1.5.0_06\bin>jarsigner.exe -keystore NONE -storetype PKCS11 D:\Applet.jar "Cinek's dp ID"
Enter Passphrase for keystore: 1111
jarsigner error: java.lang.NullPointerException
I`ve got the java.lang.NullPointerException !
To find reason of the exception I`ve written simple application, which signs a byte array:
import java.security.KeyStore;
import java.security.PrivateKey;
import java.security.PublicKey;
import java.security.Signature;
import java.security.cert.Certificate;
import java.util.Enumeration;
public class Main {
     public static void main(String[] args) throws Exception {
          PrivateKey privkey = null;
          char[] pin = { '1', '1', '1', '1' };
          KeyStore smartCardKeyStore = KeyStore.getInstance("PKCS11");
          smartCardKeyStore.load(null, pin);
          Enumeration aliasesEnum = smartCardKeyStore.aliases();
          if (aliasesEnum.hasMoreElements()) {
               String alias = (String) aliasesEnum.nextElement();
               privkey = (PrivateKey) smartCardKeyStore.getKey(alias, null);
               byte[] aDocument = new byte[100];
               Signature signatureAlgorithm = Signature.getInstance("SHA1withRSA");
               signatureAlgorithm.initSign(privkey);
               signatureAlgorithm.update(aDocument);
               byte[] digitalSignature = signatureAlgorithm.sign();
When I`ve run this application in last line in method signatureAlgorithm.sign() I got:
Exception in thread "main" java.lang.NullPointerException
     at java.math.BigInteger.modPow(Unknown Source)
     at sun.security.rsa.RSACore.crtCrypt(Unknown Source)
     at sun.security.rsa.RSACore.rsa(Unknown Source)
     at sun.security.rsa.RSASignature.engineSign(Unknown Source)
     at java.security.Signature$Delegate.engineSign(Unknown Source)
     at java.security.Signature.sign(Unknown Source)
     at Main.main(Main.java:31)
In debug, before this exception variables are:
alias= "Cinek's dp ID"
privkey =
SunPKCS11-ActivCard RSA private key, 1024 bits (id 192168768, token object, not sensitive, extractable)
  modulus:          112271510887039102410124262012976131016781096451891854145879061791454872222254764386718257162446565027910080375427552248069203548913907633164297672417327888344423061606707834842776634133861005271620794248782338105033496749719965719732501903618453514554701005390412127008091861831421936757053019877456102263703

  private exponent: null
  prime p:          null
  prime q:          null
  prime exponent p: null
  prime exponent q: null
  crt coefficient:  null
As you can see, private key has extractable attribute set, what is wrong. Attribute is set and key has no values.
I think that can be the reason of NullPointerException. (Maybe when extractable = true, sign() methods expects key values filled).
So, I can not sign anything.
I tryed to add some additional attributes to file "C:/pkcs11.cfg":
attributes(*,CKO_PRIVATE_KEY,*) = {
  CKA_EXTRACTABLE = false
but with no effect. Key was still extractable.
Can you help me to solve this problem?
PS. I`m using acpkcs211.dll (v3.2.102.0) as an implementation of PKCS#11. (Activcard says that it is PKCS#11 v2.11 implementation)
PS2. Sorry for my english

Answer 1

Can I ask you one question?
Which driver did you specify? I mean the smarcard reader driver or the smartcard itself driver?
If the second, does it come along with the card? because as far as I know I just got the smart card but no software at all (apart the smartcard reader driver).
Can you help me out with this?
thanks in advance,
Marco
