Default KeyStoreData.getPrivateKey(KeyStoreDataTicket)

Please Login to Remove!

Hi, all!

I got stuck on receiving a private key from the TrustedKeyStore. My code is:

Code:
KeyStore keyStore = TrustedKeyStore.getInstance();
Enumeration keyContainers = keyStore.elements();
while (keyContainers.hasMoreElements()) {
  KeyStoreData keyContainer = (KeyStoreData) keyContainers.nextElement();
  if ("MySPBCompany".equals(keyContainer.getLabel())) {
    Certificate certificate = keyContainer.getCertificate();
    PrivateKey privateKey = keyContainer.getPrivateKey(keyContainer.getTicket());
    if (privateKey != null) {
        // signing message using appropriate signer
    }
  }
}
The issue is I always get null value of the privateKey variable after calling "keyContainer.getPrivateKey(..)" method. It doesn't let me get private key from the KeyStore inspite of it has private key installed with the certificate (I can see a "Private Key on Device" label while viewing "MySPBCompany" certificate properties).

Does anybody know a way to get round this issue?
