I have a JAVA application which runs in windows and interacts with a Nitro HSM Key. However, when access to a key store is attempted, it results in a null pointer exception.
Setup provider as:
SmartCardHSMProvider p = new de.cardcontact.smartcardhsmprovider.SmartCardHSMProvider();
Security.addProvider(p);
Create the keystore:
KeyStore hsm = KeyStore.getInstance(“SmartCardHSMKeyStore”);
Results in:

If the following code is run:
CardTerminalRegistry r = CardTerminalRegistry.getRegistry();
Enumeration<CardTerminal> v = r.getCardTerminals();
while (v.hasMoreElements())
{
CardTerminal c = (CardTerminal)v.nextElement();
System.out.println("Card Name = " + c.getName());
}
The output is:
Card Name = Nitrokey Nitrokey HSM 0
Which matches with slot 0:
C:\Program Files\OpenSC Project\OpenSC\tools>pkcs11-tool.exe --list-slots
Available slots:
Slot 0 (0x0): Nitrokey Nitrokey HSM 0
token label : SmartCard-HSM (UserPIN)
token manufacturer : www.CardContact.de
token model : PKCS#15 emulated
token flags : login required, rng, token initialized, PIN initialized
hardware version : 24.13
firmware version : 3.3
serial num : DENK0102953
pin min/max : 6/15
It appears I have some configuration missing to tie the key store to the NitroHSM Key, as the code:
CardTerminal c = r.cardTerminalForName( “Nitrokey Nitrokey HSM 0” );
correctly returns the CardTerminal.
Thanks in advance for your help.
