Crypto++ provides version 3.0 of the Whirlpool algorithm. This version of the algorithm was submitted for ISO standardization.

Since: Crypto++ 5.2

Author: Paulo S.L.M. Barreto; Vincent Rijmen.

Version: 3.0 (2003.03.12)

=============================================================================

Differences from version 2.1:

Suboptimal diffusion matrix replaced by cir(1, 1, 4, 1, 8, 5, 2, 9).

=============================================================================

Differences from version 2.0:

Generation of ISO/IEC 10118-3 test vectors.
Bug fix: nonzero carry was ignored when tallying the data length (this bug apparently only manifested itself when feeding data in pieces rather than in a single chunk at once).
Support for MS Visual C++ 64-bit integer arithmetic.

Differences from version 1.0:

Original S-box replaced by the tweaked, hardware-efficient version.

◆ TruncatedFinal()

void Whirlpool::TruncatedFinal	(	byte *	digest,

virtual

Computes the hash of the current message.

Parameters

digest	a pointer to the buffer to receive the hash
digestSize	the size of the truncated digest, in bytes

TruncatedFinal() calls Final() and then copies digestSize bytes to digest. The hash is restarted the hash for the next message.

Precondition: COUNTOF(digest) <= DigestSize() or COUNTOF(digest) <= HASH::DIGESTSIZE ensures the output byte buffer is a valid size.

Implements HashTransformation.
