Verifiable Timestamp Service

May 30, 2025

Description

Lightweight webhook with simple GET/POST endpoints for cryptographic timestamping. Users fetch the public key via GET, then POST messages to be signed and permanently logged with a verifiable timestamp. Enables provable record-keeping of when data was received.

This service is currently housed in a private github repo, if interested, I can allow access.

Tools + Frameworks

Rust, Docker, CI/CD in Github Actions
