Description: freetiger is an implementation of the tiger hash algorithm made
looking only at the tiger reference paper (thus ignoring the reference code
until a working implementation was made). It also includes a modified version
of the main program included with the tiger reference implementation which was
used for benchmarking purposes.
It has been optimized for usage in the TTH calculation algorithm and includes
optimized versions that will calculate the hashes for the 1024 byte file chunks
and the 48 byte hash concatenation appending the proper suffix automatically
thus minimizing memory to memory copying.
Also freetiger features interleaved hashing where the hashes of two different
blocks are calculated at the same time interleaving the operations of one and
the other. Using this increases the implementation performance.
freetiger also supports SSE2 for key scheduling during the tiger rounds which
also increases performance on processors supporting it and provides an
implementation of the partial hashing scheme for a more secure password storage
when authenticating clients using the GPA command in ADC.
