```
    Signs a message.
    
    Specified by:
    
    generateSignature in interface MessageSigner
    
    Parameters:
    
    message - the message to be signed.
    
    Returns:
    
    the signature.
  - verifySignature
```
public boolean verifySignature(byte[] message,
                               byte[] signature)
```
    This function verifies the signature of the message that has been updated, with the aid of the public key.
    
    Specified by:
    
    verifySignature in interface MessageSigner
    
    Parameters:
    
    message - the message
    
    signature - the signature associated with the message
