Sample Certificate

Preview the certificate first.

Exactly what you get when you issue one — draw metadata · participant hash · masked winners · SHA-256 value. All identical to the real thing.

Numbers on this page are examplesuntil you issue one yourself.
01 · What's inside

Draw metadata, participant count, masked winners, and the SHA-256 hash of the entire result. One changed byte breaks the hash — tampering shows immediately.

02 · Who can verify

Anyone. With the certificate link, /verify recomputes the hash so you can confirm fairness yourself. No login.

03 · About PII

Masked in-browser and hashed before upload. Raw data never hits our servers. Zero leak risk.

Q&A · No. 012
FREQUENTLY · ASKEDEN
Q1Is re-drawing really impossible?
Yes. Each draw link fires once. The result is hashed immediately and sealed into a certificate.
Q2Can a participant verify they were included?
Yes — /verify lets anyone search their name or handle to confirm inclusion.
Q3How is PII handled?
Masked in-browser (‘Kim Gil-dong’ → ‘Kim G.’) before upload. The server stores only hashed values.
Q4How does payment work?
Pay per draw. KakaoPay, Toss, credit cards. No monthly subscription.
Q5Can I get a PDF certificate?
Certificate PDF download (suitable for official submissions) is on the paid plan. The web link is available on every plan.
