Legal validity and proof of integrity, without compromise.
Three guarantees working together: the signer is who they say they are, the signature has legal value and the integrity of the document can be proven by anyone.
Electronic signature
The electronic signature, compliant with the eIDAS Regulation, binds the signer to the document and protects its integrity. We are moving towards the advanced electronic signature (AES).
- Identity of the signer
- Link between signature and document
- Compliant with the eIDAS Regulation
eIDAS compliance
The European eIDAS Regulation gives legal value to electronic signatures across the Union. DOCUJET signatures meet its requirements.
- Qualified electronic seal (PAdES)
- Qualified timestamp
- Admissible as evidence across the EU
Blockchain anchoring
The fingerprint of every document is anchored to the Bitcoin blockchain: a proof of integrity that is public, immutable and independent of us.
- Anchored to the Bitcoin blockchain
- Public and immutable proof
- Verifiable without trusting DOCUJET
How anchoring works
From signature to blockchain, in five steps.
- 1
Signature and qualified seal
The PDF is signed and receives a qualified electronic seal (PAdES).
- 2
SHA-256 fingerprint
A unique digital fingerprint of the document is calculated.
- 3
Qualified timestamp
Date and time certified with legal value.
- 4
Bitcoin block
The fingerprint stays engraved in a block of the blockchain.
- 5
Public verification
Anyone can confirm the integrity, forever.
The proof lives on the public blockchain, not on our servers: it remains verifiable even if DOCUJET no longer existed.
Encryption
Documents encrypted in transit and at rest.
Audit trail
Every action is recorded and can be reconstructed.
Verification in the browser
The hash is calculated on your device: the file never leaves it.
Put transparency to the test.
