01 / THE WORKFLOW

One drop.
Three simple steps.

Just your files and their SHA-256 fingerprints, calculated on your own machine.

01

Drop your files.

Drag one file or several into the HASHME box above. On a phone, tap to choose your files. Nothing is uploaded.

ONE FILE OR A WHOLE BATCH
02

Get the fingerprint.

HASHME reads each file in small chunks and calculates its SHA-256 hash on your device. Follow the progress as it works.

LOCAL PROCESSING. ZERO UPLOADS.
03

Copy the evidence.

Copy a complete 64-character hash, or copy all results with their filenames. Clear the panel when you’re finished.

COMPLETE HASHES. EVERY TIME.

SHA-256, WITHOUT THE JARGON

A fingerprint for your file.

SHA-256 reads the contents of a file and runs them through a fixed set of mathematical steps. The result is a 256-bit fingerprint, displayed as 64 letters and numbers. The same contents always produce the same hash; even a tiny edit produces a very different-looking result. HASHME reads your file to calculate that fingerprint. It does not change the file or embed anything inside it.

Why use it? Compare a download with a hash published by a trusted source, or compare an original with a backup. Matching hashes give strong evidence that the contents match; different hashes show something changed. A hash checks integrity—it is not encryption, a virus scan or proof of who made the file.

A LITTLE MORE UNDER THE HOOD

A fingerprint, not encryption.

Does my file leave my device?

HASHME reads your file locally and calculates its SHA-256 fingerprint on your device. It does not upload your file or send filenames and results to a HASHME server. It does not write hashes, tags or metadata into the original file. Results live in this page’s memory; clearing the panel or reloading removes them.

Can I use HASHME completely offline?

Yes. Open this page while online and wait for OFFLINE READY beneath the HASHME box. Then disconnect and keep the page open: selecting files, hashing, copying results, clearing and starting again all work locally. Reopening or refreshing the website needs a connection. The Windows desktop app runs offline after installation.

What can a SHA-256 hash tell me?

A SHA-256 hash is a 64-character fingerprint of a file’s contents. You can compare it with a trusted published hash or with the hash of another copy to check integrity. Renaming a file does not change its hash. A hash is not encryption and does not establish whether a file is safe to run.

What type of files can I use?

Any file type—including documents and PDFs, photos and graphics, audio, videos, ZIP archives and software installers. HASHME calculates SHA-256 from the file’s raw data, so its format or extension does not matter. Your file stays unchanged.

Select or drop one file or several. Folders cannot be hashed directly in the browser; ZIP a folder first to calculate a hash for the ZIP file.

Is there a Windows desktop version?

Yes. HASHME v1.2 for Windows 11+ x64 adds a floating desktop strip, local verification records, Pair Match, .sha256 sidecars and SHA256SUMS manifests. Changed baselines require explicit approval before replacement.

The browser edition above generates SHA-256 fingerprints. The desktop version provides the catalogue and verification features. Check the desktop release details.

Download for Windows

Download passcode: sha256
Enter this on the download page when prompted.

Download & install

  1. Download. Select the button above, then enter sha256 when the protected download page asks for the passcode.
  2. Verify. Save the installer, right-click it, open Properties → Digital Signatures, and confirm the signer is KANE-O. Compare its SHA-256 fingerprint with the complete value below.
  3. Install. After the signature and fingerprint match, run the installer and follow the Windows prompts. Launch HASHME from the Start menu.

Windows may mark an internet download as blocked. Check the signature and fingerprint first; use Properties → Unblock only after they match.
