-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2013-15499 2013-08-29 21:13:51 --------------------------------------------------------------------------------
Name : freetiger Product : Fedora 18 Version : 5 Release : 2.fc18 URL : http://klondike.es/freetiger Summary : Free implementation of the tiger hash algorithm 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.
