Document authenticity infrastructure for official files.
Docseal lets an issuer seal an official document and lets a verifier check whether the received PDF or file is exactly the issued version.
Best first fit
Documents that leave an official issuer and must be trusted by someone else: statements, certificates, attestations, payslips, tax certificates, diplomas.

How it verifies
Compares the received file hash with the reference hash sealed at issuance.
Visibility policies

Not a signature product
