Interface PGPDigestCalculatorProvider

All Known Implementing Classes:

BcPGPDigestCalculatorProvider

public interface PGPDigestCalculatorProvider

A factory for digest algorithms. The purpose of this class is to act as an abstract factory, whose subclasses can decide, which concrete implementation to use for calculating PGP digests.

Method Summary

PGPDigestCalculator

get(int algorithm) Construct a new instance of a cryptographic digest.
