SSL Certs

This repository contains ssl certificates we use in multiple cases. We use them as a certificate for our dev docker images-v2 as well as for things like the webpack dev server in our asset-builder.

WARNING: This is a DEV utility! It should not be considered, save for production!

Why?

Using a single root ca for all our dev needs it is possible to add the ca as "trusted authority", meaning no more pesky browsers whining about "insecure certificates".

Usage

If you simply want to add the root ca to your store, you can use this guide. You can find the file you want to add under /rootca

Windows 10: Chrome, IE11 & Edge

Windows 10 recognizes .crt files, so you can right-click on RootCA.crt > Install to open the import dialog.

Make sure to select "Trusted Root Certification Authorities" and confirm.

You should now get a green lock in Chrome, IE11 and Edge.

Windows 10: Firefox

There are two ways to get the CA trusted in Firefox.

The simplest is to make Firefox use the Windows trusted Root CAs by going to about:config, and setting security.enterprise_roots.enabled to true.

The other way is to import the certificate by going to about:preferences#privacy > Certificats > Import > RootCA.pem > Confirm for websites.

npm

You can simply require the latest version of this repository through npm:

npm install @labor-digital/ssl-certs

Where is the LaborRootCA.key?

We store that in our private vault, somewhere at the north-pole, so nobody can do funny stuff with it :) Hint: LABOR_ADMIN_SHARE/SSL

How to make a new cert

Basically follow this guide.

The codes looks like this:

openssl req -x509 -nodes -new -sha256 -days 18250 -newkey rsa:4096 -keyout LaborRootCA.key -out LaborRootCA.pem -subj "/C=DE/CN=LABOR-digital-RootCA"
openssl x509 -outform pem -in LaborRootCA.pem -out LaborRootCA.crt

Localmachine.space

domains.ext:

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names
[alt_names]
DNS.1 = localmachine.space
DNS.2 = *.localmachine.space

Generate the cert:

openssl req -new -nodes -newkey rsa:4096 -keyout localmachine.space.key -out localmachine.space.csr -subj "/C=DE/ST=RLP/L=Mainz/O=LABOR-digital/CN=localmachine.space"
openssl x509 -req -sha256 -days 18250 -in localmachine.space.csr -CA LaborRootCA.pem -CAkey LaborRootCA.key -CAcreateserial -extfile domains.ext -out localmachine.space.crt

localhost

domains.ext:

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names
[alt_names]
DNS.1 = localhost
DNS.2 = *.localhost
IP.1 = 127.0.0.1

Generate the cert:

openssl req -new -nodes -newkey rsa:4096 -keyout localhost.key -out localhost.csr -subj "/C=DE/ST=RLP/L=Mainz/O=LABOR-digital/CN=localhost"
openssl x509 -req -sha256 -days 18250 -in localhost.csr -CA LaborRootCA.pem -CAkey LaborRootCA.key -CAcreateserial -extfile domains.ext -out localhost.crt
