A few years ago I recommended the Windows-only file hashing tool, Checksum. That tool seems to have been abandoned by the developer.
An alternative is the open source QuickHash GUI.
QuickHash GUI is available for Linux, Windows and Apple Mac OSX. It also supports a wider variety of hashing algorithms, including MD5, SHA1, SHA256, SHA512, xxHash, SHA-3 (256 bit), Blake2B (256) and Blake3.
The main QuickHash GUI site hosts binary downloads, and the code is available on a GitHub repository.
