Member Function Documentation

◆ AlgorithmProvider()

std::string Tiger::AlgorithmProvider ( ) const
virtual

Retrieve the provider of this algorithm.

Returns
the algorithm provider

The algorithm provider can be a name like "C++", "SSE", "NEON", "AESNI", "ARMv8" and "Power8". C++ is standard C++ code. Other labels, like SSE, usually indicate a specialized implementation using instructions from a higher instruction set architecture (ISA). Future labels may include external hardware like a hardware security module (HSM).

Note
Provider is not universally implemented yet.

Reimplemented from IteratedHashBase< word64, HashTransformation >.

Definition at line 19 of file tiger.cpp.

◆ TruncatedFinal()

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

Computes the hash of the current message.

Parameters
digesta pointer to the buffer to receive the hash
digestSizethe size of the truncated digest, in bytes

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

Implements HashTransformation.
