This plugin is no longer maintained. Gandi offers an free automated certificates for all simplehosting plans having ssl in the admin interface. This certificate is also auto-renewed automatically.

Let's Encrypt Gandi Plugin

letsencrypt-gandi is a plugin for certbot that allows you to obtain certificates from Let's Encrypt and use them with Gandi products such as Simple Hosting.


  • certbot installed on your computer
  • A Gandi API Key, which you can get from your Gandi Account
  • Root privileges may be required to use certbot on your system (read the "Avoiding sudo" section to try to work around this limitation).


The way you install the plugin will depend on how you installed certbot on your system.

In general terms, after you have installed and configured certbot itself, you'll have to clone the plugin's repository into a local folder on your computer (or download it and extract it from a Zip file). Then, you'll have to run the appropriate command to install it on your system.

The examples below will show you how to install the plugin in different scenarios.

When using certbot from its repository

If you've cloned the certbot repository on your computer, you'll need to use the pip executable distributed with it to install the plugin.

First, run ./certbot-auto --help from inside the cloned repository's folder to ensure that the necessary files are installed on your system.

Then, proceed to downloading and installing the letsencrypt-gandi plugin.

~ $ git clone
~ $ cd letsencrypt-gandi
~/letsencrypt-gandi $ ~/.local/share/letsencrypt/bin/pip install -e .

Note that the . at the end of pip install command is important.

Also note that you might have to run certbot from within its own directory, using the certbot-auto executable. In this case, replace [sudo] certbot by ./certbot-auto in the usage instructions and examples provided below.

When using a packaged version of certbot (Linux distributions)

If you installed certbot using your Linux distribution's package manager, you'll need to install and use pip to install this plugin.

Search the Web for instructions on how to install pip on your system. Once pip is installed, you should then be able to install the plugin with a simple command as exemplified below.

~ $ git clone
~ $ cd letsencrypt-gandi
~/letsencrypt-gandi $ pip install -e .

Note that the . at the end of pip install -e . command is important.

When using certbot from Homebrew on Mac OS X

If you installed certbot using the Homebrew package manager on Mac OS X, you'll need to run some (ugly) commands to install the plugin inside the correct directory.

First, locate the correct directory certbot. The path we're looking for is the one that includes the libexec/ folder:

$ find /usr/local/Cellar/certbot -name site-packages

Now you'll need to run python install --install-purelib /path/that/you/identified, making sure you set the PYTHONPATH environment variable with that same path for that command. For example:

~ $ git clone
~ $ cd letsencrypt-gandi
~/letsencrypt-gandi $ export CERTBOT_LIB="/usr/local/Cellar/certbot/0.8.0/libexec/lib/python2.7/site-packages"
~/letsencrypt-gandi $ PYTHONPATH=$CERTBOT_LIB python install --install-purelib $CERTBOT_LIB

Keep in mind that every time certbot is upgraded by Homebrew, the plugin needs to be reinstalled. As of version 0.9.3 of certbot, you can just execute the command again after replacing the correct version number to the path. Replace 'CERTBOT_VERSION_NUMBER' with the number of the last version installed by Homebrew on your system (for example '0.9.3').

~/letsencrypt-gandi $ export CERTBOT_LIB="/usr/local/Cellar/certbot/CERTBOT_VERSION_NUMBER/libexec/lib/python2.7/site-packages"
~/letsencrypt-gandi $ PYTHONPATH=$CERTBOT_LIB python install --install-purelib $CERTBOT_LIB


You'll be able to tell whether the plugin was successfully installed by running the certbot plugins command and looking for letsencrypt-gandi in the output, as in the following example:

$ [sudo] certbot plugins
* letsencrypt-gandi:gandi-shs
Description: Gandi Simple Hosting - Alpha
Interfaces: IAuthenticator, IInstaller, IPlugin
Entry point: gandi-shs = letsencrypt_gandi.shs:GandiSHSConfigurator

* [...]

If the plugin was correctly installed, you can proceed to using it.

Simple Hosting



  • Currently, only PHP and Ruby instances will work without modification of your code (in most cases). Simply follow the instructions and the plugin will take care of obtaining and installing the certificates for you.
  • Python and Node.js instance users must add a special route to their application prior to using the plugin (examples provided below)
Python instances

Python applications are handled through a WSGI application in Gandi so to get this plugin to work, you need to configure your application to serve a directory called .well-known statically from the application folder.

If you are using Django, you can do this by adding a route to your file:

    url(r'^\.well-known/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '.well-known'}),

After doing that, deploy your application to your Simple Hosting instance and use this plugin to obtain and install a certificate.

Node.js instances

To use this plugin with Node.js applications, you will have to create a special route to serve static files from a directory called .well-known.

For example, if you're using the Express framework :


Once you have added the route to the application, deploy it to your Simple Hosting instance before following the rest of the instructions.


Run the following command from your computer and make sure you replace the placeholders with your own information.

  • SHS-NAME: the name of the instance
  • VHOST: the domain name for the certificate and of the Simple Hosting VHOST
  • API-KEY: your Gandi API key
$ [sudo] certbot run --domains VHOST \
            --authenticator letsencrypt-gandi:gandi-shs \
                --letsencrypt-gandi:gandi-shs-name SHS-NAME \
                --letsencrypt-gandi:gandi-shs-vhost VHOST \
                --letsencrypt-gandi:gandi-shs-api-key API-KEY \
            --installer letsencrypt-gandi:gandi-shs

Simply follow the steps presented on the screen to complete the process.

For certificate renewal and installation execute the same command.


You can also create scripts to make this process easier for certificate creation and renewal.

Here's an example script created by @internationils, a Gandi customer.


Authentication issues

If you experience authentication issues, make sure you can connect to the instance via sftp from your terminal with your SSH Key and without a password.

If the connection via sftp works, but the script still has authentication issues, make sure you have added your SSH Key to ssh-agent on your computer (see the Requirements section for instructions).

In case everything seems to be set correctly, but the script is still not able to authenticate, try to run the above commands with sudo and re-run the script.

Other issues

You can also check previously reported Issues or create a new one if you need any help.

Other products

Support for other Gandi products, such as Web Accelerators and Servers, is not yet available through the plugin but may be added in the future.

You can still use Let's Encrypt certificates with any Gandi product.

Advanced usage

Here are some examples that are especially useful if you are developing the plugin itself.

Setting the API key in the environment

You can also set your API key in an environment variable. This way you don't need to use the --letsencrypt-gandi:gandi-shs-api-key flag.

export GANDI_API_KEY="l00km4im1nth3nv"

Avoiding sudo

certbot might require root privileges to run.

You can work around this requirement by specifiying different paths than the one it uses by default.

For example:

$ certbot --config-dir ~/.letsencrypt \
          --work-dir ~/.letsencrypt \
          --logs-dir ~/.letsencrypt/logs \

More information can be found in certbot's documentation.

certonly command

To only generate and download the certs from Let's Encrypt to your computer, you can use the certonly command with the letsencrypt-gandi:gandi-shs authenticator.

$ [sudo] certbot certonly --domains VHOST \
            --authenticator letsencrypt-gandi:gandi-shs \
                --letsencrypt-gandi:gandi-shs-name SHS-NAME \
                --letsencrypt-gandi:gandi-shs-vhost VHOST \
                --letsencrypt-gandi:gandi-shs-api-key API-KEY \

install command

To only install the certs downloaded to your computer on Simple hosting, you can use the install command and the letsencrypt-gandi:gandi-shs installer.

$ [sudo] certbot install --domains VHOST \
              --cert-path /path/to/cert \
              --key-path /path/to/cert \
              --installer letsencrypt-gandi:gandi-shs \
              --letsencrypt-gandi:gandi-shs-name SHS-NAME \
              --letsencrypt-gandi:gandi-shs-vhost VHOST \
              --letsencrypt-gandi:gandi-shs-api-key API-KEY \


With the following additional flags, you'll be able to use LE's staging server and control where your local files are kept. The log file created in ~/.letsencrypt/letsencrypt.log may contain more information about your problem.

$ [sudo] certbot --config-dir $HOME/.letsencrypt \
            --work-dir $HOME/.letsencrypt \
            --logs-dir $HOME/.letsencrypt \
            run --domains VHOST \
            --server --break-my-certs \
            --authenticator letsencrypt-gandi:gandi-shs \
                --letsencrypt-gandi:gandi-shs-name SHS-NAME \
                --letsencrypt-gandi:gandi-shs-vhost VHOST \
                --letsencrypt-gandi:gandi-shs-api-key API-KEY \
            --installer letsencrypt-gandi:gandi-shs
