Description
An md5sum-alike program that works with Tiger/THEX hashes.
tthsum generates or checks TTH checksums (root of the THEX hash tree). The Merkle Hash Tree, invented by Ralph Merkle, is a hash construct that exhibits desirable properties for verifying the integrity of files and file subranges in an incremental or out-of-order fashion. tthsum uses the Tiger hash algorithm for both the internal and the leaf nodes.
The specification of the Tiger hash algorithm is at: http://www.cs.technion.ac.il/~biham/Reports/Tiger/
The specification of the THEX algorithm is at: http://adc.sourceforge.net/draft-jchapweske-thex-02.html.
