File Hash Calculator

SHA-256/1/384/512 of a file in your browser, with reputation lookups.

Why this exists

ThreatLocker policies and most allow/deny requests key on a file's SHA-256. Computing it locally, and pivoting straight to VirusTotal or a sandbox by hash, turns 'is this safe?' into a 10-second check.

How to use

Drag a file in (or pick one), hashing happens in your browser, nothing is uploaded.
Copy the SHA-256 (toggle uppercase for ThreatLocker) or another digest.
Use the reputation links to look the hash up on VirusTotal, ANY.RUN, and more.

Hashed locally in your browser, never uploaded.

Hashing happens entirely on this device, the file is never uploaded. Only the hash itself is sent if you click one of the reputation links below.
