FileHasher

FSP Productions, LLC·FSPProductions.FileHasher

Windows GUI utility to hash files and folders, write sidecar hash files, and export results to CSV.

FileHasher computes cryptographic hashes for individual files or whole folder trees, writes .sha256-style sidecar files, verifies existing sidecars, and exports results to CSV. It can optionally open .msi installer packages read-only and hash the files contained inside them individually. Ships as a signed, self-contained single executable; no .NET runtime install is required.
