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()
|
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 >.
◆ InitState()
|
static |
◆ Transform()
◆ TruncatedFinal()
|
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. The hash is restarted the hash for the next message.
Implements HashTransformation.
