Verify a drawing record

Every completed drawing is published together with a digital signature. Paste the signed record below, or just the id from a drawing link, to confirm that the record is authentic and that nothing in it has been changed since it was published.

What this proves

A valid signature confirms three things:

  1. The record was issued by OnlineRandomizer.com.
  2. It has not been modified since it was published.
  3. The source file behind it is the exact file recorded at the time, down to the byte.

The record contains the drawing number, its name, the completion time, the number of entries and winners, a SHA-256 fingerprint of the uploaded file, a fingerprint of the winners list, and the random seed source used.

This is an integrity check on the published record. It confirms what was published and when, and that nobody has tampered with it since.

Verify it yourself

You do not have to take our word for the check above. Signatures are Ed25519 over the exact record text, so any standard crypto library can verify them offline using our public key:
