cert

Overview

cert is command line utility to generate a self-signed X.509 certificate for a TLS server. Outputs to cert.pem and key.pem and will overwrite existing files. It is based on the generate-cert tool included with the go source -- only slightly modified to take more arguments.

Prerequisites

None, binaries are statically linked. If you want to compile from source you need the go toolchain.

Installation

• Save binary to a location in your PATH (i.e. /usr/local/bin/)
