- Method Detail
  - getUsageIdentifier
```
org.bouncycastle.asn1.ASN1ObjectIdentifier getUsageIdentifier()
```
    Return the usage OID specifying the signature type.
    
    Returns:
    
    algorithm oid.
  - getOutputStream
```
java.io.OutputStream getOutputStream()
```
    Returns a stream that will accept data for the purpose of calculating a signature for later verification. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
    
    Returns:
    
    an OutputStream
  - verify
```
boolean verify(byte[] expected)
```
    Parameters:
    
    expected - expected value of the signature on the data.
    
    Returns:
    
    true if the signature verifies, false otherwise
