mkcert is a simple CLI tool for making locally-trusted development certificates. It requires no configuration.
mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you.
$ mkcert -install
Created a new local CA at "/Users/filippo/Library/Application Support/mkcert" 💥
The local CA is now installed in the system trust store! ⚡️
The local CA is now installed in the Firefox trust store (requires restart)! 🦊
$ mkcert example.com "*.example.org" myapp.dev localhost 127.0.0.1 ::1
Using the local CA at "/Users/filippo/Library/Application Support/mkcert" ✨
Created a new certificate valid for the following names 📜
- "example.com"
- "*.example.org"
- "myapp.dev"
- "localhost"
- "127.0.0.1"
- "::1"
The certificate is at "./example.com+5.pem" and the key at "./example.com+5-key.pem" ✅
