ANNOUNCEMENT

I have released another PKI utility named acert.
It is a Golang project and independent of OpenSSL.
Options, options... 🤔


Self Signed SSL

This script simplifies the creation of certificate authorities, signing requests and self-signed TLS certificates using OpenSSL.

Video Tutorial

Self-Signed SSL - Introduction Video


Installation


Homebrew (MacOS)

brew tap lstellway/formulae
brew install lstellway/formulae/self-signed-ssl

cURL

curl --output self-signed-ssl https://raw.githubusercontent.com/lstellway/self-signed-ssl/master/self-signed-ssl && chmod +x self-signed-ssl

Usage

self-signed-ssl [OPTIONS]

# Run with no arguments to be prompted for required values
self-signed-ssl

# Only create a certificate authority and trust the generated certificate
self-signed-ssl --ca-only --trust

# Only create a certificate signing request
self-signed-ssl --csr-only

# Generate a signed certificate using existing files
self-signed-ssl --ca='/path/to/CA.pem' --ca-key='/path/to/CA.key' --csr='/path/to/EXAMPLE.csr'

# Automate certificate generation
self-signed-ssl --no-interaction -c 'US' -s 'California' -l 'Los Angeles' -o 'Example Org' -u 'Example Unit' -n 'example.com' -a 'www.example.com'
