    Default Creating keyring files for data encryption

    Hi there,

    I've been reading about data encryption in this link.
    My doubt comes in the end:

    Java Code:
    protected SecretKey lookupSecretKey(String id) {
        SecretKey key = null;
    
        // Get the key-ring file name from the property list for this agent
        String keyringFile = System.getProperty("keyring", "keyring.dat"); //IN THIS LINE
    
        // Try reading the key-ring and looking up the key for the id
        try {
            // Read the key-ring from disk
            ObjectInputStream in =
                new ObjectInputStream(new FileInputStream(keyringFile));
            Hashtable keyring = (Hashtable) in.readObject();
            // Lookup the id's key on the ring
            key = (SecretKey)keyring.get(id);
        }
        catch (Exception e) {
            System.err.println("Failure looking up key on keyring.");
            e.printStackTrace(System.err);
        }
    
        return key;
    }
    In the referred line, how am I supposed to generate a keyring? I've been 'googling' about the topic, but I can find nothing more that some IBM links that speak about some kind of software (owned by them, of course), that uses this kind of files.
