This section describes the Uanataca Timestamp (TSA) product and service. For the full product overview and documentation index, see the Timestamp homepage.
Uanataca Timestamp is a qualified timestamp service (TSA) with full legal value, compliant with European Regulation 910/2014 and RFC-3161 (Time-Stamp Protocol). The service does not use a REST API; it uses request/response messages over TCP (e.g. over HTTP with curl and OpenSSL).
- What it does — Binds reliable date and time and integrity to data; provides irrefutable proof that data existed before a given time.
- How it works — Client sends a hash (e.g. SHA-256) in a timestamp request (.tsq); TSA returns a signed timestamp token (.tsr). The original document is never sent.
For endpoints, authentication, and usage, see GET STARTED. For the step-by-step workflow with OpenSSL and curl, see Usage reference.
