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,
		size_t	digestSize
	)

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() call Final() and then copies digestSize bytes to digest

TruncatedFinal() restarts the hash for the next message.

Precondition: COUNTOF(digest) == DigestSize() or COUNTOF(digest) == HASH::DIGESTSIZE ensures the output byte buffer is large enough for the digest.

Implements HashTransformation.
