Member Function Documentation

virtual void HashTransformation::Final ( byte *  digest)
inlinevirtualinherited

compute hash for current message, then restart for a new message

Precondition
size of digest == DigestSize().

Definition at line 545 of file cryptlib.h.

Referenced by PKCS5_PBKDF2_HMAC< T >::DeriveKey(), RandomPool::IncorporateEntropy(), and HMAC_Base::TruncatedFinal().

virtual bool HashTransformation::Verify ( const byte *  digest)
inlinevirtualinherited

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.
