プロジェクトの歴史

The badkeys GitHub repository was created in January 2022. Its README says the tool checks public keys in multiple formats for known vulnerabilities, with a public web version at badkeys.info.

The README credits Hanno Boeck as author, says the work was initially funded in 2022 through the CIDI project and CISAT at the IT University of Copenhagen, and notes later 2025/2026 support from NLnet's NGI0 Core Fund.

採用の歴史

The project is distributed through PyPI and appears in Homebrew and Nix in the batch package metadata. The README also points users to Repology for distribution packages, suggesting upstream expected operating-system packaging beyond Python-only installation.

Release names show the project expanding its checks over time, including DKIM support in 2024, parser robustness and return-code improvements in 2026, and a 'Post-Quantum Edition' release in June 2026.

使われ方

badkeys users first download blocklist data with badkeys --update-bl, then scan key, certificate, CSR, SSH public key, TLS host, or SSH host material. The README documents return codes that distinguish application errors, parser problems, and vulnerable keys.

Its command-line use is intentionally automation-friendly: quiet output when no vulnerable keys are found, an all-keys output flag for audits, and bitmask return codes for CI or batch scans.

パッケージ好きにとっての重要性

badkeys is package-nerd relevant because it turns a pile of cryptographic failure cases into a reusable CLI and library with data updates. Packaging it gives security teams a repeatable way to scan public keys without copying ad hoc scripts around.

It also illustrates a modern security package pattern: a small Python CLI, external vulnerability/blocklist data, optional network scanning modes, and package-manager availability for workstation and CI installation.
