wxChecksums!

The HashCheck Shell Extension makes it easy for anyone to calculate and verify checksums and hashes from Windows Explorer. In addition to integrating file checksumming functionality into Windows, HashCheck can also create and verify SFV files (and other forms of checksum files, such as .md5 files). It is fast and efficient, with a very light disk and memory footprint, and it is open-source.

[Hashtab is free for personal use for Windows, NOT for Mac: it can be bought for $1.99 from the Mac App Store.]

HashMyFiles is small utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system.

Md5Checker is a free, faster, lightweight and easy-to-use tool to manage, calculate and verify MD5 checksum of multiple files/folders

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

QuickSFV integrates into the Windows Explorer shell and makes it very easy to verify files. Just double-click on the SFV file and QuickSFV does the rest. QuickSFV also understands several other file verification formats including CRC, CSV, and CKZ. For even quicker verification of SFV files, QuickSFV remembers which files have been previously verified and will skip them in future checks. You can always tell QuickSFV to go back and verify all files again just to be sure.

GUI frontend for fsum – a hash calculator supporting a ton of algorithms.

FileVerifier++ is a Windows application for verifying the integrity of files. FileVerifier supports various algorithms by means of dynamically loadable hash libraries. It uses the Windows API and doesn't have any dependencies other than what comes with Windows (WinFVC excluded).

Currently supported hash functions include CRC32, ADLER32, GOST, MD2, MD4, MD5, MD6, SHA1, SHA2, SHA3, RIPEMD, HAVAL, TIGER, WHIRLPOOL and BLAKE2.

MD5summer is an application for Microsoft Windows 9x, NT, ME, 2000 and XP which generates and verifies md5 checksums. Its output file is compatible with the output of the Linux GNU MD5Sum and it will also read Linux generated files. MD5summer is written in Borland Delphi 7. Source is available from the download page.

CHK is an advanced checksum utility — a simple application designed to help you verify the integrity of your files, find duplicates and much more!Main Features

checksum is an easy-to-use, no-nonsense BLAKE2, SHA1 & MD5 hashing program for Windows, capable of creating & verifying hashes of files and folders, even whole drives, with just one or two clicks. It is robust, lightning fast, intuitive, and completely customizable. It comes with an installer that adds hashing options to your Explorer menus, or alternatively, can be simply unzipped for portable operation. Or both.

MD5 & SHA Checksum Utility is a tool that allows you to generate CRC32, MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of single or multiple files. You can also verify hashes with the matching file to ensure the file integrity is correct.

cfv is a utility to both test and create .sfv, .csv, .crc, .md5(sfv-like), md5sum, bsd md5, sha1sum, and .torrent files. These files are commonly used to ensure the correct retrieval or storage of data.
