A fork of 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard.

PeaZip is free file archiver utility, based on Open Source technologies of 7-Zip, p7zip, FreeArc, PAQ, and PEA projects.

With over 500 million users worldwide, WinRAR is the world’s most popular compression tool!

There is no better way to compress files for efficient and secure file transfer. Providing fast email transmission and well-organized data storage options, WinRAR also offers solutions for users working in all industries and sectors.

WinRAR is a powerful archiver extractor tool, and can open all popular file formats.

RAR and WinRAR are Windows 10 (TM) compatible; available in over 50 languages and in both 32-bit and 64-bit; compatible with several operating systems (OS), and it is the only compression software that can work with Unicode.

Though console applications are open source (PAR clients are GPL), GUI application is closed source.
Console applications and some UI resource are open source.

TurboSFV - Software for the calculation and validation of checksums for files. Supported hash algorithms: SHA3-224, SHA3-256, SHA3-384, SHA3-512, xxHash (XXH32, XXH64), BLAKE2S-256, BLAKE2B-256, BLAKE2B-384, BLAKE2B-512, SHA-224, SHA-256, SHA-384, SHA-512, SHA-1, MD5, CRC-32.
TurboSFV produces hash values for files located in folders, folder trees or for all files on a drive. A separate menu entry allows to turn the recursive search for files on and off.
TurboSFV saves the hash values either in a summary checksum file, in one file per folder or per file. For each calculation process, it's easy to switch between the three creation modes.
TurboSFV properly handles files with Unicode characters in file or folder names and can also read from and write to hash files which are encoded in UTF-8 or UTF-16.

RapidCRC is an open source CRC/MD5/SHA hashing program.

This is a mod of the original RapidCRC .

The current unicode support was extended to allow writing of unicode .sfv/.md5/.sha1/.sha256/.sha512 files, which can be turned on/off through the settings page. Unicode sfv files are written as UTF-16LE with BOM or UTF-8 (with or without BOM), and RCRC performs a codepage detection.

RHash (Recursive Hasher) is a console utility for computing and verifying hash sums of files. It supports CRC32, MD4, MD5, SHA1, SHA256, SHA512, Tiger, DC++ TTH, BitTorrent BTIH, ED2K, AICH, GOST R 34.11-94, RIPEMD-160, HAS-160, EDON-R 256/512, Whirlpool and Snefru-128/256 algorithms. Hash sums are used to ensure and verify integrity of large volumes of data for a long-term storing or transferring.

Features:

Can calculate Magnet links.
Output in a predefined (SFV, BSD-like) or user defined format.
Ability to process directories recursively.
Updating of existing hash files (adding sums of files missing in the hash file).
Calculates several hash sums in one pass.
Portability: the program works the same under Linux, *BSD, or Windows.
