Java Security

Hello, everybody.

i am trying to write a sample application in order to access the certificates stored in safesign usb token.

I installed the pkcs11 driver provided by A.E.T ( aetpkss1.dll ) and then i write the following code :

/***********************************************/
try {

String configName = "c:/pkcs11.config";
sun.security.pkcs11.SunPKCS11 p = new sun.security.pkcs11.SunPKCS11(configName);
Security.addProvider(p);

char[] pin = {'1','2','3','4'};
KeyStore.Builder builder = KeyStore.Builder.newInstance("pkcs11",p ,new KeyStore.PasswordProtection(pin) );
KeyStore ks = builder.getKeyStore();

X509Certificate x509Cert = null;
Certificate c;

for (Enumeration list = ks.aliases(); list.hasMoreElements();) {
String alias = (String) list.nextElement();
System.out.println(alias);
c = ks.getCertificate(alias);

x509Cert = (X509Certificate) c;
System.out.println("--> Subject: " + x509Cert.getSubjectDN().getName());
System.out.println("--> Issuer: " + x509Cert.getIssuerDN().getName());

}
}

catch (Exception e) { e.printStackTrace(); }
/**************************************/

The configuration file contains the following two lines :

name = Safesign
library = c:\windows\system32\aetpkss1.dll


when i run this code I get the following exception :

java.security.KeyStoreException: KeyStore instantiation failed

Can anybody give me an explanation why is this happening ??
The token administrator utility shows that usb token works fine.


Thanks in advance.
