2. Setup valid HTTPS¶
This page shows you how to use the Devilbox on https and how to import the Certificate Authority into your browser once, so that you always and automatically get valid SSL certificates for all new projects.
SSL certificates are generated automatically and there is nothing to do from your side.

Valid HTTPS will automatically be available for all projects

2.1. TL;DR¶
Import the Certificate Authority into your browser and you are all set.
2.2. How does it work¶
2.2.1. Certificate Authority¶
When the Devilbox starts up for the first time, it will generate a
Certificate Authority
and will store its public and private key in
./ca/
within
the Devilbox git directory.
The keys are only generated if they don’t exist and kept permanently if you don’t delete them manually, i.e. they are not overwritten.
host> cd path/to/devilbox
host> ls -l ca/
-rw-r--r-- 1 cytopia cytopia 1558 May 2 11:12 devilbox-ca.crt
-rw------- 1 cytopia cytopia 1675 May 2 11:12 devilbox-ca.key
-rw-r--r-- 1 cytopia cytopia 17 May 4 08:35 devilbox-ca.srl
2.2.2. SSL Certificates¶
Whenever you create a new project directory, multiple things happen in the background:
- A new virtual host is created
- DNS is provided via Setup Auto DNS
- A new SSL certificate is generated for that vhost
- The SSL certificate is signed by the Devilbox Certificate Authority
By having a SSL certificates signed by the provided CA, you will only have to import the CA into your browser ones and all current projects and future projects will automatically have valid and trusted SSL certificates without any further work.
2.3. Import the CA into your browser¶
Important
Importing the CA into the browser is also recommended and required for the Devilbox
intranet page to work properly.
You may also import the CA into your Operating System’s Keystore. Information on that
is available at
GFI Root Certificate guide
.
