Seal Soft
To seal and authenticate locally on Windows. Demonstrable capabilities: sealing, local certificates, Windows store inventory, local vault.
With CertiShielder™, protect the trust in your documents and digital identities
Seal, authenticate and verify — without turning trust into an overengineered mess.
Today, the heart of the offer is Seal Soft: a Windows application to seal and authenticate your documents locally. Seal Web and Sovereign Trust Gateway complete the range — they are still in progress, and we say so clearly.
The brand
Why CertiShielder?
Files move. So do signatures. Certificates expire. And the Internet has an excellent memory — certificates do too. Digital trust is not a marketing badge: it is a set of concrete gestures — sealing a document, checking that it has not changed, caring for the certificates that say who is speaking, protecting the keys you do not lend, even to your best friends.
We design tools to make these gestures readable day to day — first on the Windows workstation with Seal Soft, then on the web and in organisations with the building blocks still in progress.
Write to be understood, not to impress — even when the subject is cryptographic.
Vision
Digital trust, without the jargon
Sealing means attaching proof of integrity and authenticity to a document — in Soft, via the PAdES, CAdES and XAdES formats. Verifying means checking that proof before you grant trust. Certificates are the cryptographic identity cards of machines and people: useful, worth inventorying, sometimes worth renewing.
When the format allows it, that verification can also be replayed on public validators from the European Commission, for example DSS Validation or the eIDAS / EFDA validation tests. Useful for having a third party re-read a signature — without turning trust into an act of faith.
Our approach stays pragmatic. No promise of inviolability. No “100% secure”. Demonstrable capabilities, named limits, and teaching so the black box stops being one.

Ecosystem
Three ways to approach trust
One product line, distinct roles, honest statuses. Soft first.
In progress
Seal Web
To verify from a browser. A verify-only companion — no signing in the browser.
In progress · not commercialized
Sovereign Trust Gateway
To orchestrate trust in B2B and B2G contexts. A distinct product. Sales are not open.
How they fit
How they work together
Seal Soft is the workstation: you act there, you seal there. Seal Web (in progress) aims at site-side verification. Gateway (in progress) aims at trust coordination between organisations. Three roles, one shared rule: do not promise what is not yet demonstrated.

Guidance
Which product is right for you?
Pick your situation. We point you the right way — without jargon, and without inventing a capability.
I am an SME
Start with Seal Soft: local sealing on Windows, offer on pre-order.
I am a public administration
Soft for the local gesture today. Gateway remains a B2G orchestration perspective — not commercialized.
I develop an application
Soft provides a local API and a CLI. Seal Web verify is in progress for the browser.
I need a signing or sealing solution
Seal Soft (PAdES, CAdES, XAdES). Locally generated certificates do not make a qualified eIDAS signature, unless a QTSP certificate or service is used.
I want to automate renewals
A real need — not a capability presented as available in Soft or Gateway. ACME guidance is in the Knowledge Center.
Commercial priority
What Seal Soft does today
Demonstrable capabilities. Offer on pre-order. Commercial industrialisation (installer, licence, sales go-live) continues.
-
Document sealing
Documents sealed and authenticated in PAdES, CAdES and XAdES formats, with an associated proof layer — including EviDNA™ in Soft.
-
Local certificates
Generation or PKCS#12 import. Locally generated certificates do not constitute a qualified eIDAS signature, unless a certificate or service issued by a QTSP is used.
-
Windows inventory
A view of certificates present in the machine’s Windows stores.
-
Local vault
Encrypted vault with segmented key (patent FR3063365 B1).
Differentiating technology
The added value of EviDNA™
Sealing a document is already proof of integrity and authenticity (PAdES, CAdES, XAdES). EviDNA™ adds a procedural proof layer delivered in Seal Soft: a traceable fingerprint, a sequence identifier, a manifest — so trust stays verifiable, including offline.
-
Complements the signature, does not replace it
Document formats bind the document via a certificate. EviDNA™ brings the procedural layer: proof, ACGT genome, TrustSequence and JSON manifest.
-
A readable fingerprint, not biological DNA
The A/C/G/T alphabet is a symbolic encoding of a derived fingerprint. A clear metaphor for following a proof — not a forensic genetic proof.
-
Local verification and anchoring in Soft
A local EviDNA verification layer, with optional local anchoring offline. A badge or QR can accompany the proof — without inventing a remote TSA.
What EviDNA™ is not: content encryption, a legal identity, or a substitute for a qualified eIDAS signature (QES). Technology delivered in Seal Soft — not a separate commercial product, not a live Gateway integration.
