pi_registrar — authenticated IP address registrar
Built a client-server service that records hosts’ current IPv4 and IPv6 addresses against their certificate identities. The client creates a signed JSON Web Token from its certificate and submits it over HTTPS; the server validates the certificate against a configured certificate authority before accepting the registration.
- Address registration: Supports IPv4 and IPv6, with a client that can resolve and connect using either address family.
- Storage and DNS: Keeps the latest registered address and timestamp in SQLite, and can optionally update DNS records using authenticated dynamic DNS.
- Deployment: Includes systemd service and timer packages for Debian and Arch Linux, so the client can periodically refresh a host’s address.
- Technologies: Python, CherryPy, SQLite, PyJWT, Cryptography, dnspython, PyYAML, systemd, Debian packaging, and Arch Linux packaging.
