27 longDescription = ''
28 tthsum generates or checks TTH checksums (root of the THEX hash
29 tree). The Merkle Hash Tree, invented by Ralph Merkle, is a hash
30 construct that exhibits desirable properties for verifying the
31 integrity of files and file subranges in an incremental or
32 out-of-order fashion. tthsum uses the Tiger hash algorithm for
33 both the internal and the leaf nodes.
