org.bouncycastle.openpgp.operator

public Interface PGPDigestCalculator

Known Direct Implementers: org.bouncycastle.openpgp.operator.bc.SHA1PGPDigestCalculator, org.bouncycastle.openpgp.operator.jcajce.SHA1PGPDigestCalculator
Imports: java.io.OutputStream, org.bouncycastle.bcpg.HashAlgorithmTags

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

Method Summary

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