...After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. Brotli is open-sourced under the MIT License. ...

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

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. It is based on python lzhw library. Full tool documentation can be found at: https://mnoorfawi.github.io/lzhw/6%20Using%20the%20lzhw%20command%20line%20tool/ While the documentation for the python library is at: https://mnoorfawi.github.io/lzhw/

This software zips and unzips a .txt file, using the Huffman encoding algorithm and the list and tree data structures. The result files are named zippedFile.txt and unzippedFile.txt and can be found at the same directory as the Text Zip executable file.

Lectures on Huffman Code mostly focus on creating the Huffman Tree and converting the given data into the new bitmap. But what about the informations needed to create the Huffman Tree? They must be stored as well. With this project I want to test some possibilities to store these data. gmp,h is needed to compile. See: http://gmplib.org/

hufc is a utility to compress or expand files using Huffman coding. It can use a 16-bit CRC or the IP checksum for error detection.

THIS PROJECT HAS BEEN MOVED TO GITHUB: http://github.com/drichardson/huffman

This project is built for learning purposes so it's implementation is kept simple and easy to read. It has two functions to either encode or decode a file with the expectation that you will modify it to suite your needs best.

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

A compression engine based on the Huffman trie algorithm. The algorithm is pretty cpu-light, and as such, runs much more quickly than RAR or other 'heavy' algorithms, but could still achieve decent compression. Use with tar for multi-file archives.

The algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode message. Built tree is n-ary one.The algorithm is based on a set of template classes : Cell(SYMBOL, WEIGHT), Node(
