However, some protocols have been defined with support for a custom tree hashing with the Tiger hash function, under the name "TTH" (Tiger Tree Hash) or "THEX" (Tree Hash Exchange Format). The specification for TTH appears to be a bit elusive; I find some references to drafts which have either moved or disappeared for good. Still, I am a bit dubious about the concept. It is kind of neat, but ... Hash keying is also known as convergent encryption. This keying and encryption is a cryptosystem that produces ciphertext from plain text. Cloud computer is one area where hash keying has an application. This is because with hash keying you complete operations without giving the provider access to encryption tools. This process was developed in the mid 1990’s. In 2011 Bitcasa – a cloud ...

Fsum Frontend was added by Kissaki in Sep 2011 and the latest update was made in Oct 2020. The list of alternatives was updated Mar 2020. Hash tree, Merkle tree, Tiger tree hash; eDonkey2000 file hash (single-level tree with ~9 MiB block size) Just like what you're doing, these methods takes the list of block hashes and hashes that again, down to a single short hash. Since this is a well established practice, I would assume that it is as secure as sequential hashing. A hash function is an algorithm that transforms (hashes) an arbitrary set of data elements, such as a text file, into a single fixed length value (the hash). The computed hash value may then be used to verify the integrity of copies of the original data without providing any means to derive said original data. Irreversible, a hash value may be freely distributed, stored and used for ...
