Add a verify page beside OpenTimestamps

Keep your .ots proofs. Certify the file in docstoc for people who will not run ots-client.

Why there’s no “Connect your account” button

File certificates are hashes of bytes, not e-sign envelopes. We do not connect to Adobe or DocuSign accounts. Export the original file you need to prove, then certify it here.

Exporting from OpenTimestamps

  1. 1Keep the original file and any .ots proof you already have.
  2. 2Certify the same file in docstoc for a public link.
  3. 3Do not delete your OTS proofs if they matter legally to you.

Once you have the files

Drop the file in the hash checker or create a certificate in the app. Share the verification link. Optional Bitcoin timestamping is available on accounts that enable it.

Just doing this once?

Hash in the browser — the file does not need to leave your machine for a client-side check.

Making it the new default?

Issue a full certificate when you want a durable public verify page.

Where your files end up

Keep the original file. The certificate proves that this exact file still matches — it is not a qualified electronic signature.
