Detailed Description

Tiger message digest.

Crypto++ provides the original Tiger hash that was submitted to the NESSIE project. The implementation is different from the revised Tiger2 hash.

Member Function Documentation

AlgorithmProvider()

std::string Tiger::AlgorithmProvider

(

)

const

Definition at line 19 of file tiger.cpp.

InitState()

void Tiger::InitState ( HashWordType *  state )

static

Initialize state array.

Parameters

state

the state of the hash

Definition at line 30 of file tiger.cpp.

StaticAlgorithmName()

CRYPTOPP_STATIC_CONSTEXPR const char * Tiger::StaticAlgorithmName ( )

inline

Definition at line 38 of file tiger.h.

Transform()

void Tiger::Transform ( word64 *  digest, const word64 *  data  )

static

Operate the hash.

Parameters

digest	the state of the hash
data	the data to be digested

Definition at line 54 of file tiger.cpp.

TruncatedFinal()

void Tiger::TruncatedFinal	(	byte *	digest,
		size_t	digestSize
	)

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.
