Check that a draw's seed matches the SHA-256 hash shown on the result

SHA-256 hash (from the result / certificate)

Seed (from the result / certificate)

How does it work?

1Each draw uses a random 256-bit seed; the result shows the seed and the SHA-256 hash (also on the PDF certificate).
2Paste both values here: we compute SHA-256 of the seed in your browser and compare it with the hash.
3Automatic draws also get a public result page with the same hash, confirming the published result was not edited afterwards.
