Package org.bouncycastle.operator

Interface MacCalculator

public interface MacCalculator

General interface for a key initialized operator that is able to calculate a MAC from a stream of output.

Method Summary

Modifier and Type	Method	Description
AlgorithmIdentifier	getAlgorithmIdentifier()
GenericKey	getKey()	Return the key used for calculating the MAC.
byte[]	getMac()	Return the calculated MAC based on what has been written to the stream.
OutputStream	getOutputStream()	Returns a stream that will accept data for the purpose of calculating the MAC for later verification.

Method Details

getAlgorithmIdentifier

AlgorithmIdentifier getAlgorithmIdentifier()

getOutputStream

OutputStream getOutputStream()

Returns a stream that will accept data for the purpose of calculating the MAC for later verification. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.

Returns:

an OutputStream

getMac

byte[] getMac()

Return the calculated MAC based on what has been written to the stream.

Returns:

calculated MAC.

getKey

GenericKey getKey()

Return the key used for calculating the MAC.

Returns:

the MAC key.
