Certified exports
Verify a manuscript certificate
Check the assistance recorded in Prosa, where the manuscript's history begins, and whether the certificate belongs to this exact export. Your manuscript stays in your browser. The record supports an author's disclosure; it cannot establish what happened outside Prosa.
1. The exported manuscript
The file Prosa produced with the certificate, exactly as it was saved. Any change to it, even one character, changes its fingerprint.
2. The certificate
Paste the signed certificate as Studio shows it after a certified export, or choose the certificate file downloaded with your manuscript (.json).
Your manuscript never leaves your browser: it is fingerprinted here and the signature is checked here. Asking Prosa whether the certificate was revoked sends only the certificate and the fingerprint.
