How VeeSign Cryptographically Establishes Trust
In high-stakes legal, financial, and government transactions, trust is not a feeling — it is mathematical proof. Discover the forensic architecture behind every agreement.
Forensic Non-Repudiation for Strategic & Regulated Deals
VeeSign combines signer authentication, a PAdES digital signature with an RFC 3161 timestamp, and a timestamped audit trail into one evidence record for each agreement.
7-Stage Cryptographic Trust Sequence
Canonical Ingestion
Instant binary hashing to lock PDF byte stream and prevent subsequent mutation.
Canonical Document Ingestion
When a document is uploaded, VeeSign parses its binary stream and generates an initial canonical SHA-256 cryptographic hash.
Signer Identity Assertion
Each signer is authenticated by the method the sender requires: email link, access code, account sign-in, passkey, authenticator-app two-factor, email or SMS one-time code, or a national-ID signature.
Interactive Affirmative Consent
Explicit user intent is captured via interactive viewport consent triggers, recording IP, timestamp, and device telemetry.
PAdES Digital Seal
The completed PDF is sealed with a PAdES signature, using the "VeeSign Document Signing" certificate issued by Veebase LLC (RSA 3072-bit) or the organization's own key. Each signer who signs with a national ID adds a PAdES signature from their own certificate, and all signatures stay valid.
Tamper-Evident Audit Trail
Every event is recorded in a timestamped audit trail, and VeeSign stores the SHA-256 fingerprint of the signed PDF. Any post-signing change breaks the signature.
Audit Certificate Issuance
An audit certificate is attached to the PDF, recording who signed, when, from which IP, and how each signer was authenticated. The signature carries a timestamp from an RFC 3161 timestamp authority configured by the customer.
Independent verification
Auditors or courts can verify the document on the public verification page (app.veesign.net/verify) without needing a VeeSign account or exposing private content.
