Security
Every document signed through Docuplete receives a trusted timestamp issued by an independent RFC 3161-compliant time-stamping authority. This provides cryptographic, independently verifiable proof of when each signature was applied.
What it covers
Technical details
RFC 3161 is the Internet standard for trusted timestamping. A compliant TSA signs a hash of your document with its private key and the current time — creating a cryptographic receipt.
A signature's legal validity can erode over time if the signing certificate expires. An RFC 3161 timestamp locks in the validity of the signature at the moment it was applied — preserving it for years or decades.
The timestamp is bound to a SHA-256 hash of the document. Any modification to the document after signing produces a different hash — making the timestamp verification fail and the modification detectable.
Docuplete uses an accredited, independent time-stamping authority. The timestamp can be verified without Docuplete's involvement — using any RFC 3161-compliant verification tool.
The combination of OTP identity verification, RFC 3161 trusted timestamp, and SHA-256 tamper detection aligns with the requirements for advanced electronic signatures under eIDAS.
RFC 3161 trusted timestamps are included on all Docuplete plans — Starter through Enterprise. There is no additional cost and no configuration required.
