Brotli
Brotli compression format
...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. ... -

web.py
Web framework for python that is as simple as it is powerful
web.py is a web framework for Python that is as simple as it is powerful. web.py is in the public domain, you can use it for whatever purpose with absolutely no restrictions. web.py was originally published while Aaron Swartz worked at reddit.com, where the site used it as it grew to become one of the top 1000 sites according to Alexa and served millions of daily page views. “It’s the anti-framework framework. web.py doesn’t get in your way,” explained founder Steve Huffman. (The site was rewritten using other tools after being acquired by Condé Nast.) The latest stable release 0.62 only supports Python >= 3.5. If you are still using Python 2.7, then please use web.py version 0.51 which is intended to be our last release that supports Python 2. -

Wuffs
Wrangling Untrusted File Formats Safely
...The design prioritizes predictable performance: decoders avoid dynamic allocation by default, return explicit “short read” signals, and run well in streaming or sandbox-free environments. The project ships battle-tested, CPU-friendly implementations for common image/container formats and bit-twiddly primitives like Huffman and checksum routines. Its standard library emphasizes portability and constant-time behavior where appropriate, which is valuable in security-sensitive contexts. Because the language is purpose-built, the resulting C output is small, auditable, and easy to embed in larger systems. -

libjpeg-turbo
SIMD-accelerated libjpeg-compatible JPEG codec library
...On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface. -

Bzip2 for Windows
A block-sorting file compressor, v1.0.6 for Win-32
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
NGINX module for Brotli compression
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. -

EECE350 Huffman Coding
Huffman Coding Description
The Huffman Coding is used for compressing files and reducing the size of data. The algorithm assign different type of data to to binary representation. The length of a binary number depends on a frequency of this data appears in the file. If it appears often, the binary representation wil contain less bits and vice versa. -
