public Interface PGPDigestCalculatorProvider

Known Direct Implementers: org.bouncycastle.openpgp.operator.bc.BcPGPDigestCalculatorProvider
Imports: org.bouncycastle.bcpg.HashAlgorithmTags, org.bouncycastle.openpgp.PGPException

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.
