|
|
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.
