Securing SSH Connections Using a Certificate on macOS or Linux
Below you’ll find the individual steps to secure your SSH connection to a server using a certificate (SSH key).

1. Create an SSH Key

Open the terminal on your Mac (or Linux system) and run the following command to generate an SSH key pair:
Bash
```
ssh-keygen -t ed25519 -C "deine_email@example.com"
```

- The -C "your_email@example.com" adds a comment, such as your email address, to the key.
