ZOOBC / SHA-256
Hash a file
Drop any file to calculate its SHA-256 locally in your browser. Nothing is uploaded.
Choose a network
The hasher is the same tool on either network: it does arithmetic on a file and never touches the chain. The rows are here only so you land on the gateway you were already using.

01 / WHAT IT DOES
One number, computed locally
Drop one or more files and it prints their SHA-256. The work happens in your browser, so nothing is uploaded and the tool works with the network disconnected.
It makes no claim about whether a file is genuine. For that you want Verify a download, which takes the same hash and asks the chain whether ZooBC published it.
02 / WHY IT IS SEPARATE
A calculator, not an authority
Keeping the hasher separate from the verifier is deliberate. A hash on its own is a fact about bytes that anyone can reproduce; whether the chain vouches for those bytes is a different question with a different answer.
Every file zoobc.com hosts lists its fingerprint on Official files, so you can hash a download here and compare the two strings without trusting either page.
