RFC 3161 timestamp receipt
Written by Agorean from what the endpoint says about itself
Proves a piece of data existed at a certain time, without sending the data.
Takes a SHA-256 digest you already computed and returns a Time-Stamp Authority's signed RFC 3161 token over it, proof that whatever you hashed existed at that time. Your data itself is never sent, only its hash, and nothing about the request is retained. Up to 10 digests can be batched into one call bound by a Merkle root. No account or API key is needed.
WHEN TO USE THIS
When: I need to prove something existed at a certain time to someone who has no reason to trust me
For example: Hash it yourself, submit the digest, and keep the returned token as evidence.
When: I have several things to timestamp at once
For example: Submit up to 10 digests together to get them bound by a single Merkle-root timestamp.
When: I need to verify a timestamp token later without contacting this service
For example: Verify the RFC 3161 token directly against the time-stamp authority.
