One-Liner for Self-Signed Certificates in Go

A handy one-liner for when you need a self-signed certificate while writing an HTTP server in Go.

go run $(go env GOROOT)/src/crypto/tls/generate_cert.go -rsa-bits 2048 -host localhost

This will generate cert.pem and key.pem.

I used to rely on openssl or mkcert, but this seems to work well when using Go.
