history

Project history and usage

sigsum-go is the Go implementation and command-line toolkit for Sigsum key-usage transparency.

Project history

sigsum-go is the principal Go implementation of Sigsum, a system for key-usage transparency based on signed checksums, append-only logs, witnesses, and monitors. The module contains command-line clients and reusable Go packages implementing Sigsum formats and protocols.

Adoption history

Sigsum remains a focused transparency ecosystem rather than a general-purpose signing platform. Its official documentation lists Go, C, and Rust implementations and provides tooling for users, monitors, log operators, and witnesses.

How it is used

Users generate Ed25519 keys, sign and submit checksums to a configured log, collect witness-backed proofs, verify proofs offline, and monitor logs for use of selected signing keys. Trust policies identify accepted logs, witnesses, and quorum rules.

Why package nerds care

sigsum-go interests release engineers because it supplies compact, interoperable tools for proving that signed checksums were publicly logged. Offline proof verification and witness-backed append-only guarantees suit reproducible release and package-verification workflows.

Timeline

2021: Sigsum's early design and implementation work became public.
2024: Current development moved to the Glasklar GitLab service.
2025: The official getting-started workflow documented the 0.14 series and built-in trust policies.

Related projects

Officially documented related implementations include sigsum-c and sigsum-rs. The broader system also includes Sigsum log servers, witnesses, bastions, monitors, and community-maintained trust policies.
