Prove a payslip is genuine.We never see it.
PaySeal certifies the fingerprint of a payslip. The file goes straight from the employer to the employee to whoever asks for it — we never receive it, and we could not produce it if asked.
We are opening employer accounts in France first.

Below is a fragment of a payslip and its SHA-256 fingerprint, taken as it was issued. Edit the text: the second fingerprint follows every keystroke. When the two stop matching, that is what a verifier sees.
Nothing leaves this page. The text and both fingerprints stay in your browser.
- as issued
- as edited
A real payslip is a PDF, and PaySeal fingerprints the file itself. Plain text is used here only so that you can edit it.
Three roles
Each role does one thing.
None of them uploads a payslip to PaySeal. The file travels between the people who need it; only a fingerprint reaches us.
Honest limits
We certify payslips we have never seen.
A verification that claims too much is worth nothing. Here is the exact boundary, so that the part that holds is worth something.
It proves
That a verified employer certified this exact file, on this date, for this recipient. The signature cannot be forged. Any change to the file breaks the match.
It does not prove
That the figures on the payslip are true. PaySeal never reads a payslip and could not. That responsibility stays with the employer who signed it.
