    LZ4

    LZ4

    Extremely fast compression algorithm

    LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's...

    Zstandard

    Zstandard

    Zstandard - Fast real-time compression algorithm

    Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer...

    Brotli

    Brotli

    Brotli compression format

    Version 1.0.9 contains a fix to "integer overflow" problem. This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. 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...

    Naeon

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    Naeon is a secure cloud storage solution that uses unbreakable military-grade encryption and zero-knowledge privacy to protect confidential data in an untrusted environment. The data are encrypted using the AES 256-bit encryption algorithm with a randomly generated 128-character passphrase. Then, it is split into small pieces called chunks, which are obfuscated by adding random data to each chunk to make them unreadable and indecipherable to unauthorized individuals or processes...

    LZWStream

    The LZW algorithm in C#

    Implementation of the LZW algorithm in C#, adhering to the built-in System.IO.Compression. The algorithm and code is much improved, compared to projects like SharpLZW. The LZW algorithm is for arbitrary lossless data compression and are noticeable for simplicity and low (compared to others) memory consumption. Making it interesting for eg. embedded use. There're many other LZW implementations out there. This one is focused on KISS and C#.

    Firefly's Clean Lzo

    A human-readable ISC-Licensed implementation of the LZO1X algorithm.

    LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C...
