# Encrypt Private Key

Before FOMO will run, you must generate an encrypted key on the server. This will create your encrypted key file locally. **Keep it safe.**

Run the command below **from the same folder** as the `FOMO` binary. **Note:** format for private key should look like this: `[226,242,156,...]` . No spaces between numbers.\
\
This will generate an encrypted file in the same folder, called: **encrypted\_pk**. Re-running the command, using a different private key will override the existing one.

```shell
./FOMO encrypt-key [your_private_key]
```
