Signatures that
stay verifiable
for decades.
SignFlow seals the cryptographic proof inside every PDF. Always verifiable — independent of the provider, the certificate authority, or SignFlow itself.
Proof that lasts
Ordinary signatures fade. Ours hold.
Certificates expire, providers disappear, authorities change. SignFlow embeds the trust chain, timestamp, revocation data and archive timestamps directly inside the document — self-contained proof, verifiable offline.
- Verifiable in 2050 thanks to archive timestamps (B-LTA).
- Provider-independent — the proof travels with the PDF.
- Offline verification via an exportable proof bundle.

One flow, three levels
The right level of assurance, every time.
SES, AES and QES under one signing experience — the level adapts without switching tools.
Simple
Internal consent and low-stakes documents. Instant setup, full traceability.
Advanced
Binding cross-organization contracts. Identity verified by one-time code before signing.
Qualified
Legal equivalent of a handwritten signature. Qualified certificate, maximum evidentiary value.
The platform
A clear command center, from draft to proof.
