To create locally a certificate you need the [OpenSSL](https://www.openssl.org/) command-line tool.
Change to your Home Assistant [configuration directory](/getting-started/configuration/) like `~/.homeassistant`. This will make it easier to backup your certificate and the key. Run the command shown below.
Change to your Home Assistant [configuration directory](/getting-started/configuration/) like `~/.homeassistant`. This will make it easier to backup your certificate and the key. Run the command shown below.
The certificate **must** be `.pem` extension.
If you are going to use this certificate with the iOS app, you need to ensure you complete **all** fields during the cetificate creation process, then:
* Send **only** `certificate.pem` file to the iOS device using airdrop or other transfer method.
* Open the `.pem` file on the iOS device, follow the prompts to trust and install it.

```bash
$ openssl req -new -x509 -sha256 -newkey rsa:4096 -nodes -keyout privkey.pem -days 730 -out fullchain.pem
$ openssl req -sha256 -newkey rsa:4096 -nodes -keyout key.pem -x509 -days 730 -out certificate.pem
```
For details about the parameters, please check the OpenSSL documentation. Provide the requested information during the generation process. At the end you will have two files called `privkey.pem` and `fullchain.pem`. The key and the certificate.
