CFSSL is Cloudflare's PKI/TLS toolkit for signing, verifying, and bundling TLS certificates, available as both a command line tool and an HTTP API server. It also includes packages for building custom PKI tools, a multi-root certificate authority server, and utilities for generating keys, CSRs, and certificate bundles.
Use cases
- generate private keys and certificate signing requests
- run a lightweight internal certificate authority
- sign and verify TLS certificates
- build certificate chain bundles for HTTPS sites
- serve a JSON API for certificate issuance
- create self-signed certificates for development
When to choose
- you need to operate your own internal CA or sign certificates programmatically
- you want a CLI and HTTP API for certificate generation and bundling
- you need Go packages to build custom PKI tooling
When to avoid
- you only need to obtain certificates from a public CA like Let's Encrypt (use certbot or acme clients)
- you need a full-featured enterprise PKI with revocation infrastructure like CRL/OCSP at scale
- you need a GUI-based certificate manager
