Receipt verifier
Check it yourself
A tool run on the shared engine writes a Receipt: the size and hash of what went in, the size and hash of what came out under a plain name such as qr-maker-1.svg, and what the page saw on the network while it ran. An output made from what you typed keeps its size only, so nobody can test guesses at it. Drop a Receipt here with the files it describes and this page will tell you whether they belong together. Nothing is uploaded. The checking happens in this tab, against your bytes.
1. The Receipt
The .json file the tool offered you after it ran. Receipts from version 1 still check.
2. The files it describes
The outputs from that run, under any name. A Receipt keeps no file name you saved, chose or typed, so files are matched by their contents. You can add the input files too, and they are recognised by their hash. Leave out a private output: the Receipt keeps no hash of it, so there is nothing to check it against.
