A free, EU-hosted RFC 3161 timestamp authority. Same protocol, same "free forever" posture as FreeTSA.org — disclosed operator instead of an anonymous personal server.
Standard RFC 3161 over HTTP. Any client that speaks to FreeTSA already
speaks to this — point it at eurotsa.eu/tsr instead.
openssl ts -query -data myfile -cert -sha256 -out request.tsq curl -sSH "Content-Type: application/timestamp-query" \ --data-binary @request.tsq https://eurotsa.eu/tsr -o response.tsr openssl ts -verify -in response.tsr -data myfile \ -CAfile eurotsa-root.crt.pem -untrusted eurotsa-chain.crt.pem
Download the certificate chain — needed to verify a timestamp independently of eurotsa.eu itself.
sha256, sha384, sha512. No md5/sha1 — no reason to carry broken digest algorithms into a service built in 2026.
Operator: SPRK10 B.V., a company registered in the Netherlands.
Service description: EuroTSA issues RFC 3161 trusted timestamps. It is not a qualified trust service under eIDAS — no CAB audit, no ETSI EN 319 421/422 compliance, no EU Trusted List filing. It carries the same evidentiary weight as any other non-qualified RFC 3161 timestamp.

Privacy: EuroTSA does not log submitted hashes or document content. Requester IP addresses are held only transiently, in the rate limiter's sliding window, and are never persisted to disk or a database.
