ContentVerifier (Bouncy Castle Library 1.68 API Specification)

```
public interface ContentVerifier
```
General interface for an operator that is able to verify a signature based on data in a stream of output.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`org.bouncycastle.asn1.x509.AlgorithmIdentifier`	`getAlgorithmIdentifier()`	Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
`java.io.OutputStream`	`getOutputStream()`	Returns a stream that will accept data for the purpose of calculating a signature for later verification.
`boolean`	`verify(byte[] expected)`	Return true if the expected value of the signature matches the data passed into the stream.

- Method Detail
  - getAlgorithmIdentifier
```
org.bouncycastle.asn1.x509.AlgorithmIdentifier getAlgorithmIdentifier()
```
    Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
    
    Returns:
    
    algorithm oid and parameters.
  - 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)
```
    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
