Interface OutputVerifier<T extends Parameters>

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

Methods

Modifier and Type	Method and 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
