## 4. Data Structures

### 4.1 Witness Registration
```java
package jcifs.internal.witness;

import java.net.InetAddress;
import java.util.concurrent.atomic.AtomicLong;

public class WitnessRegistration {
    private final String registrationId;
    private final String shareName;

```java
HandshakeCertificates serverHandshakeCertificates = new HandshakeCertificates.Builder()
    .heldCertificate(serverCertificate, intermediateCertificate.certificate())
    .build();
```

The client only needs to know the trusted root certificate. It checks the server's certificate by
validating the signatures within the chain.
