- Method Detail
  - hasFullMessage
```
boolean hasFullMessage()
```
    Returns true if the signer has recovered the full message as part of signature verification.
    
    Returns:
    
    true if full message recovered.
  - getRecoveredMessage
```
byte[] getRecoveredMessage()
```
    Returns a reference to what message was recovered (if any).
    
    Returns:
    
    full/partial message, null if nothing.
  - updateWithRecoveredMessage
```
void updateWithRecoveredMessage(byte[] signature)
                         throws InvalidCipherTextException
```
    Perform an update with the recovered message before adding any other data. This must be the first update method called, and calling it will result in the signer assuming that further calls to update will include message content past what is recoverable.
    
    Parameters:
    
    signature - the signature that we are in the process of verifying.
    
    Throws:
    
    java.lang.IllegalStateException
    
    InvalidCipherTextException
