There are adjacent use cases that mkcert might be good for, like acting as a CA infrastructure for microservices, but that's not what mkcert is for. The hardest part of the project, besides figuring out half a dozen different root stores, has been keeping the tool simple and focused. (That is, it uses Subject Alternative Names, instead of the 20-years-deprecated Common Name.)

It even works on mobile devices with a couple manual steps.Īlso, unlike OpenSSL, it does the right thing by default, instead of forcing you to use a dozen flags and materialize a config file for each certificate. It supports macOS, Linux, and Windows, and Firefox, Chrome and Java.

The local CA is now installed in the Firefox trust store (requires browser restart)! 🦊 The local CA is now installed in the system trust store! ⚡️ So when your browser loads a certificate generated by your instance of mkcert, it will show up with a green lock! $ mkcert -install Here's the twist: it doesn't generate self-signed certificates, but certificates signed by your own private CA, which your machine is automatically configured to trust when you run mkcert -install. The certificate is at "./+2.pem" and the key at "./+2-key.pem" ✅ Using the local CA at "/Users/filippo/Library/Application Support/mkcert" ✨Ĭreated a new certificate valid for the following names 📜 It works for any hostname or IP, including localhost, because it only works for you. Mkcert is a simple by design tool that hides all the arcane knowledge required to generate valid TLS certificates. Developing with HTTPS should be as easy as deploying with HTTPS. This is a problem because more and more browser features are being made available only to secure origins, and testing with HTTP hides any mixed content issues that can break a production HTTPS website. But HTTPS needs TLS certificates, and while deployment is increasingly a solved issue thanks to the ACME protocol and Let's Encrypt, development still mostly ends up happening over HTTP because no one can get an universally valid certificate for localhost.

The web is moving to HTTPS, preventing network attackers from observing or injecting page contents. Mkcert: valid HTTPS certificates for localhost
