## Member Function Documentation

virtual void HashTransformation::Final | ( | byte * | digest | ) | `[inline, virtual, inherited]`

| compute hash for current message, then restart for a new message Precondition: size of digest == DigestSize(). Reimplemented in PKCS_DecoratedHashModule< H >, SignatureEncodingMethodWithRecovery, and EMSA2DecoratedHashModule< H >. Definition at line 526 of file cryptlib.h. Referenced by HashFilter::Put2(), PK_SignerBase< H >::SignAndRestart(), and PK_VerifierBase< H >::VerifyAndRestart().

virtual bool HashTransformation::Verify | ( | const byte * | digest | ) | `[inline, virtual, inherited]`

| verify that digest is a valid digest for the current message, then reinitialize the object Default implementation is to call Final() and do a bitwise comparison between its output and digest. Reimplemented in SignatureEncodingMethodWithRecovery. Definition at line 549 of file cryptlib.h. Referenced by VerifierWithRecoveryTemplate< TF, H >::VerifyAndRestart().
