longDescription = ''
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:
