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.

Retrieve the provider of this algorithm.
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).

virtual |
Computes the hash of the current message.
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.
