TinyCA

Your very own tiny certificate authority!

A tiny project consisting of two bash scripts and two folders that will neatly organize certificates for use in development projects.

It's fast to setup and pretty straight-forward!

Requirements

• Linux Environment with a Terminal
• OpenSSL [ sudo apt install openssl ]

Usage

First clone this repository using git,

git clone https://github.com/Naushikha/TinyCA.git
cd TinyCA

Then follow these steps to create your own certificates,

1. Generating your own TinyCA (Tiny Certificate Authority)

./gen_CA.sh

• Fill in the required details.

• If done right, you should be able to see your CA files (key & root certificate) in the 'CA' folder.

2. Generating certificate with the TinyCA

./gen_CERT.sh my-awesome-sitename.com

• Give your own site name here to generate a certificate for it.

• If done right, you can find your certificates in a seperate folder with your site name in the 'Sites' folder.

Examples

Here are some placeholder values to get an idea on what to fill in,

Country Name (2 letter code) [AU]: LK
State or Province Name (full name) [Some-State]: Western
Locality Name (eg, city) []: Colombo 10
Organization Name (eg, company) [Internet Widgits Pty Ltd]: Awesome Software Pty Ltd
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []: www.awesomesoftware.com
Email Address []: [email protected]

Known Issue

I've recently encountered an issue while using this where the certificate isn't trusted by Google Chrome. This can be fixed by swapping in 'IP.1 = $DOMAIN' for 'DNS.1 = $DOMAIN' in the script, and also including in the IPs as domain name + FQDN.
