Homomorphic hashing in golang

Package tz containts pure-Go implementation of hashing function described by Tillich and Źemor in [1] .

There are existing implementations already (e.g. [2]), however it is written in C.

Package gf127 contains arithmetic in GF(2^127) with x^127+x^63+1 as reduction polynomial.

Description

It can be used instead of Merkle-tree for data-validation, because homomorphic hashes are concatable: hash sum of data can be calculated based on hashes of chunks.

The example of how it works can be seen in tests.
