history
Project history and usage
signify-osx is a small, audit-oriented macOS port of OpenBSD's signify file-signing utility.
Project history
signify-osx ports OpenBSD's signify(1) utility to macOS. The maintainer states that it tracks upstream OpenBSD sources directly and minimizes portability changes to preserve auditability.
Adoption history
The port is available through Homebrew and MacPorts. Comparable signify implementations are also packaged across several Unix-like operating systems, reflecting the utility's role in lightweight package and artifact verification.
How it is used
Users generate or supply signify key pairs, sign files with a secret key, and verify signatures with a public key. Package-oriented use centers on authenticating release manifests and downloaded artifacts.
Why package nerds care
signify is closely associated with OpenBSD's minimalist approach to signed releases and packages. The macOS port deliberately keeps its portability layer small so users can compare and audit it against upstream OpenBSD sources.
Timeline
- 2014: OpenBSD introduced signify for signing and verifying releases.
- 2015: signify-osx began providing the utility to OS X users.
- 2019: The port documented testing through macOS 10.14 and continued direct tracking of OpenBSD sources.
Related projects
- OpenBSD signify(1) is the authoritative upstream utility.
- The portable `signify` implementations packaged by other operating systems serve the same signing and verification format.
