```
public SignatureProcessorImpl(Signature signature)
```
    The constructor.
    
    Parameters:
    
    signature - the Signature to use.
- Method Detail
  - getSignature
```
protected Signature getSignature()
```
    Returns:
    
    the underlying Signature.
  - getAlgorithm
```
public String getAlgorithm()
```
    Specified by:
    
    getAlgorithm in interface CryptoAlgorithm
    
    Returns:
    
    the name of the underlying algorithm (e.g. "RSA", "NONEwithECDSA", etc.).

    Key.getAlgorithm(), Signature.getAlgorithm(), MessageDigest.getAlgorithm(), SecureRandom.getAlgorithm(), Cipher.getAlgorithm()
  - update
```
public void update(byte[] input,
                   int offset,
                   int length)
```
    Specified by:
    
    update in interface CryptoChunker
    
    Parameters:
    
    input - the next chunk of data.
    
    offset - the index where to start reading data from input.
    
    length - the number of bytes to read from input.
    
    See Also:
    
    MessageDigest.update(byte[], int, int), Signature.update(byte[], int, int)
  - reset
```
public void reset()
```
    Description copied from interface: CryptoProcessor
    
    Will reset the internal state of this object. Please note that complex algorithms especially for Cryptor may not reusable. It is therefore preferable to always create a fresh instance for each cryptographic task.
    
    Specified by:
    
    reset in interface CryptoProcessor
    
    See Also:
    
    MessageDigest.reset()
