...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. ...

This is a research project to possible improve compression using LZ77, LZSS or bwt, bwt is used on the bzip2 compression library, the v28 from 04/dec/2022 is the first version to almost beat lzma, indeed it is a tweak of lzma, the decoder for v28 will follow in a few days

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.

Bzip2 compresses files using the Burrows-Wheeler block sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than that achieved by more conventional LZ77/LZ78-based compressors, and approaches the performance of the PPM family of statistical compressors. by Julian Seward.

ngx_brotli is a set of two Nginx modules developed by Google that enable Brotli compression for web content delivery. Brotli is a modern, general-purpose, lossless compression algorithm combining an optimized variant of LZ77, Huffman coding, and second-order context modeling. It provides compression ratios comparable to the best general-purpose compressors while maintaining speeds similar to Deflate (gzip). These modules help websites and APIs deliver smaller payloads, resulting in faster page loads, reduced bandwidth usage, and better Core Web Vitals.

CRUSH is a simple LZ77-based file compressor that features an extremely fast decompression.

liblzg is a minimal implementation of an LZ77 class compression library. The main characteristic of the library is that the decoding routine is very simple, fast and requires no memory.

The shrink library provides a single API into several compressionalgorithms. It enables developers to easily add compression and decompression functionality to an existing code base. Currently it supports: LZO LZ77 LZMA

Simple LZ77 coder with parametrized buffer and dictionary size for better data adaptation. Written in Java. For experimental and study purposes.
