mkcert

mkcert is a convenient tool for creating locally trusted development certificates. Using certificates from real certificate authorities (CAs) for local development can be challenging if not impossible (for hosts such as example.test, localhost or 127.0.0.1). In such situations self-signed certificates may be your only option. mkcert lets you generate self-signed certificates and installs the local CA in the system root store. For anything other than local development and testing, we strongly recommend using certificates from real CAs to avoid trust issues.
