Interface PGPDigestCalculator

public interface PGPDigestCalculator

A digest calculator, which consumes a stream of data and computes a digest value over it.

Method Summary

Modifier and Type	Method and Description
int	getAlgorithm() Return the algorithm number representing the digest implemented by this calculator.
byte[]	getDigest() Return the digest calculated on what has been written to the calculator's output stream.
java.io.OutputStream	getOutputStream() Returns a stream that will accept data for the purpose of calculating a digest.
void	reset() Reset the underlying digest calculator

Method Detail

getAlgorithm

int getAlgorithm()

Return the algorithm number representing the digest implemented by this calculator.

Returns:

the hash algorithm number

getOutputStream

java.io.OutputStream getOutputStream()

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

Returns:

an OutputStream that data to be digested can be written to.

getDigest

byte[] getDigest()

Return the digest calculated on what has been written to the calculator's output stream.

Returns:

a digest.

reset

void reset()

Reset the underlying digest calculator
