# Hass.io Core Add-on: Letsencrypt
|
||
|
||
Let's Encrypt is a certificate authority that provides free X.509 certificates for Transport Layer Security encryption via an automated process designed to eliminate the hitherto complex process of manual creation, validation, signing, installation, and renewal of certificates for secure websites.

|
||
|
||
## About
|
||
|
||
Setting up Letsencrypt allows you to use validated certificates for your webpages and webinterfaces.
|
||
It requires you to own the domain you are requesting the certificate for.
|
||
|
||
The generated certificate can be used within others addons.
|
||
|
||
## Installation
|
||
|
||
The installation of this add-on is straightforward and easy to do.
|
||
|
||
1. Navigate in your Home Assistant frontend to **Hass.io** -> **Add-on Store**.
|
||
2. Find the "letsencrypt" add-on and click it.
|
||
3. Click on the "INSTALL" button.
|
||
|
||
## How to use
|
||
|
||
To use this add-on, you have two options on how to get your certificate:
|
||
|
||
1. http challenge
|
||
- Requires Port 80 to be available from the internet and your domain assigned to the externally assigned IP address
|
||
- Doesnt allow wildcard certificates (*.yourdomain.com).
|
||
|
||
2. dns challenge
|
||
- Requires you to use one of the supported DNS providers (See "Supported DNS providers" below)
|
||
- Allows to request wildcard certificates (*.yourdomain.com)
|
||
- Doesn’t need you to open a port to your hass.io host on your router.
|
||
|
||
You always need to provide the following entries within the configuration:
|
||
|
||
```json
|
||
"email": "your@email.com"
|
||
"domains": "yourdomain.com" /// in case of requesting a wildcard certificate, add "*.yourdomain.com".
|
||
"challenge": "http OR dns"
|
||
```
|
||
|
||
IF you choose "dns" as "challenge", you will also need to fill:
|
||
```json
|
||
"dnsprovider": "" (Add the dnsprovider of your choice from the list of "Supported DNS providers" below)
|
||
|
||
In addition add the fields according to the credentials required by your dns provider:
|
||
