history
Project history and usage
certstrap is Square's Go-based CLI for bootstrapping certificate authorities, certificate requests, and signed certificates. Its README describes it as a simple certificate manager adapted from etcd-ca and intended as a friendlier alternative to hand-writing OpenSSL commands and config files.
Project history
The public repository was created in 2015 and the release history includes v1.0.0/v1.0.1 in 2016, later 1.1 and 1.2 releases, and v1.3.0 in 2022. The project documents building from source with Go and contributing through the upstream repository.
Adoption history
certstrap became a packaged PKI helper across multiple ecosystems. The supplied package facts list APK, Homebrew, MacPorts, Nix, and Scoop packages, matching its role as a small standalone executable for development and internal PKI workflows.
How it is used
Typical certstrap usage starts by initializing a CA, then generating identity keys and CSRs, and finally signing certificate requests. By default, generated keys, CSRs, certificates, and CRLs are placed in the depot directory, documented as out/.
Why package nerds care
certstrap matters in package catalogs because it turns the brittle OpenSSL local-CA bootstrap routine into a reproducible CLI. It is especially visible to developers who need throwaway or internal TLS material without adopting a larger PKI system.
