Digital document sealing and verification

AMX TrustMesh

Seal your documents digitally. Let anyone verify them in seconds.

AMX TrustMesh seals invoices, certificates and contracts with a quantum-resistant cryptographic signature and puts a QR code on every document so the recipient can verify it in seconds. It runs on your own machines and server; your documents never leave your network.

Acerca de este producto

Every day your organisation issues documents other people rely on: an invoice a bank pays against, a certificate of origin that clears a shipment, a degree that gets a graduate hired. Each one is a PDF in which a number can be changed without a trace.

AMX TrustMesh closes that gap. It seals the document with a cryptographic signature bound to its exact content, so any later change — even a single digit — shows at once on verification. The recipient needs no account and no special software: they upload the file to the verification page or scan the QR code with a phone.

What sets it apart

Any edit shows at once: changing one byte of a sealed document fails verification.
Quantum-resistant: a dual signature combining Ed25519 and ML-DSA-65; both must be valid.
Your documents never leave your network: sealing happens on your machines and your server.
Works offline: sealing and licensing run in a fully isolated network.
International standards: PDFs signed to PAdES that open in any reader, with an RFC 3161 timestamp.
Works with the systems you have: it watches the output folder and seals every new file, with no change to your accounting or banking system.
A tamper-evident log: every sealed document is recorded in a hash-chained log, and any document can be revoked.

Components

Server (Linux): the core, an API, a public verification site and the sealing console, hosted on your own server.
Desktop program (Windows): seal a file, a whole folder, or automatically, with no server.
Mobile app (Android): verify by scanning the QR code.

Who it is for

Banks and financial institutions, trade and shipping companies, universities, and any body that issues documents others rely on.
