File hash / checksum
Fingerprint any file with SHA-256, SHA-1 or SHA-512 — and check it against the hash a download page published.
Hashing uses your browser's built-in crypto engine — files never leave your device.
How to verify a download
- Drop the file you downloaded (or paste text).
- Copy the expected hash from the download page into the “Compare” box.
- Match = safe. A green match means the file is byte-for-byte identical to what the publisher released.
Frequently asked questions
Why verify checksums at all?
Corrupted downloads and tampered installers are real. Two seconds of hash-checking confirms the file you got is exactly the file that was published.
Which algorithm should I pick?
Match whatever the publisher listed — usually SHA-256 nowadays. All three are computed at once here, so just compare against the right one.
What about MD5?
MD5 is obsolete and not offered by the browser's crypto engine. If a site only lists MD5, treat that as a hint the site is dated — SHA-256 is the standard.
