  - getAlgorithmIdentifier
```
 abstract AlgorithmIdentifier getAlgorithmIdentifier()
```
    Return the algorithm identifier describing the signature algorithm and parameters this signer generates.
    
    Returns:
    
    algorithm oid and parameters.
  - getOutputStream
```
 abstract OutputStream getOutputStream()
```
    Returns a stream that will accept data for the purpose of calculating a signature. Use io.anyline.nfc.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
    
    Returns:
    
    an OutputStream
  - getSignature
```
 abstract Array<byte> getSignature()
```
    Returns a signature based on the current data written to the stream, since the start or the last call to getSignature().
    
    Returns:
    
    bytes representing the signature.
