HashCheck is a Windows Explorer shell extension that lets users verify and generate file checksums (MD5, SHA-1, SHA-2, SHA-3, and more) directly from file properties and the context menu. It is a maintained fork of the original HashCheck tool from code.kliu.org, adding SHA2/SHA3 support and multithreading.

Use cases

• verify checksums of downloaded files from windows explorer
• generate md5 or sha256 hash of a file
• create and check sfv or md5sum files
• compare a file against a checksum list
• integrity-check large downloads before use

When to choose

• you need checksum verification integrated into windows explorer
• you want a lightweight, free, native windows tool for file hashing
• you need to create or verify checksum files like .sfv or .md5

When to avoid

• you need a cross-platform or command-line-only hashing solution
• you are not on windows vista or later
• you need hashing of directories with exotic formats not supported by the extension
