OutputVerifier

Type Parameters:

T - the parameters type for the verifier.

All Known Subinterfaces:

OutputVerifierWithMessageRecovery<T>

All Known Implementing Classes:

FipsOutputVerifier
```
public interface OutputVerifier<T extends Parameters>
```
Base interface for an output verifier which can be used to verify a signature against a data stream.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`T`	`getParameters()`	Return the parameters for this output verifier.
`UpdateOutputStream`	`getVerifyingStream()`	Returns a stream that will accept data for the purpose of verifying a previously calculated signature.
`boolean`	`isVerified(byte[] signature)`	Return true if the data written to the verifying stream matches the data the signature was calculated against.

- Method Detail
  - getParameters
```
T getParameters()
```
    Return the parameters for this output verifier.
    
    Returns:
    
    the verifier's parameters.
  - getVerifyingStream
```
UpdateOutputStream getVerifyingStream()
```
    Returns a stream that will accept data for the purpose of verifying a previously calculated signature. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
    
    Returns:
    
    an UpdateOutputStream
  - isVerified
```
boolean isVerified(byte[] signature)
            throws InvalidSignatureException
```
    Return true if the data written to the verifying stream matches the data the signature was calculated against.
    
    Parameters:
    
    signature - the signature to be confirmed.
    
    Returns:
    
    true if the data verifies against the signature, false otherwise.
    
    Throws:
    
    InvalidSignatureException
