Request your certificate directly
If your certificate never arrived, ask for it here with the register number and college email on your enrolment. You do not need an account.
How it works
Three steps to secure issuance.
The participant list is securely uploaded by your department. Everything else is completely automated.
Identify yourself
Register number, @rathinam.in email and your name. All three must match the same record on the participant list.
We render and seal it
Generated server-side at 300 DPI, watermarked, and signed with the University's private key. Nothing is generated in your browser.
Download and share
PNG or PDF, both print-ready. Anyone can confirm it later by scanning the QR code.
Common Questions
My name is spelled wrong. Can I fix it?
The name is taken from the participant list your department uploaded — it is not something you can type. Ask your department to correct the list. Once a certificate has been issued the record is frozen, so they will also need to revoke and reissue it.
I already downloaded mine. Can I get it again?
Yes. Enter the same details and you will get the same certificate back, with the same code. There is exactly one certificate per student and it never changes.
Why does it not work with my personal email?
Only @rathinam.in addresses are accepted, and only the address on the participant list for your register number. This is what stops someone else claiming your certificate.
What does the QR code actually prove?
It carries the certificate's code and an Ed25519 signature over the printed details. Anyone can check that signature against the University's public key — so even a PDF found years from now can be verified without trusting this website.
