Method Details

getParameters

public abstract T getParameters()

Description copied from interface: OutputVerifier

Return the parameters for this output verifier.

Specified by:

getParameters in interface OutputVerifier<T extends Parameters>

Returns:

the verifier's parameters.

getVerifyingStream

public abstract UpdateOutputStream getVerifyingStream()

Description copied from interface: OutputVerifier

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.

Specified by:

getVerifyingStream in interface OutputVerifier<T extends Parameters>

Returns:

an UpdateOutputStream

isVerified

public abstract boolean isVerified(byte[] signature)
                            throws InvalidSignatureException

Description copied from interface: OutputVerifier

Return true if the data written to the verifying stream matches the data the signature was calculated against.

Specified by:

isVerified in interface OutputVerifier<T extends Parameters>

Parameters:

signature - the signature to be confirmed.

Returns:

true if the data verifies against the signature, false otherwise.

Throws:

InvalidSignatureException
