`abstract AlgorithmIdentifier`	`getAlgorithmIdentifier()`	Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
`abstract OutputStream`	`getOutputStream()`	Returns a stream that will accept data for the purpose of calculating a signature for later verification.
`abstract boolean`	`verify(Array<byte> expected)`	Return true if the expected value of the signature matches the data passed into the stream.

  - getAlgorithmIdentifier
```
 abstract AlgorithmIdentifier getAlgorithmIdentifier()
```
    Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
    
    Returns:
    
    algorithm oid and parameters.
  - getOutputStream
```
 abstract OutputStream getOutputStream()
```
    Returns a stream that will accept data for the purpose of calculating a signature for later verification. Use io.anyline.nfc.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
    
    Returns:
    
    an OutputStream
  - verify
```
 abstract boolean verify(Array<byte> expected)
```
    Return true if the expected value of the signature matches the data passed into the stream.
    
    Parameters:
    
    expected - expected value of the signature on the data.
    
    Returns:
    
    true if the signature verifies, false otherwise
