LZHW Windows command line lossless compression tool for tabular files
LZHW Command Line Lossless Compression Tool
is a Windows command line tool used to compress and decompress files from and to any form, csv, excel etc without any dependencies or installations.
Using an optimized algorithm (LZHW) developed from Lempel-Ziv, Huffman and LZ-Welch algorithms.
The tool can work in parallel and most of its code is written in Cython, so it is pretty fast.
A human-readable ISC-Licensed implementation of the LZO1X algorithm.
...So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language.
I expect a severe performance degradation, but I leave optimizing for speed to other people.
