How to Set Up SSH Keys on Your Raspberry Pi for Secure Access?
Setting up SSH keys on your Raspberry Pi is a straightforward process that significantly enhances the security of your remote IoT platform. Here’s a step-by-step guide to help you get started:
- Generate SSH Keys: On your local machine, open a terminal and run the command
ssh-keygen. This will generate a pair of cryptographic keys: a private key and a public key. - Copy the Public Key to Raspberry Pi: Use the command
ssh-copy-id pi@your_raspberry_pi_ipto copy the public key to your Raspberry Pi. Replaceyour_raspberry_pi_ipwith the actual IP address of your Raspberry Pi. - Disable Password Authentication: To ensure maximum security, disable password authentication on your Raspberry Pi by editing the SSH configuration file. Run
sudo nano /etc/ssh/sshd_configand setPasswordAuthenticationtono. - Restart SSH Service: After making changes to the configuration file, restart the SSH service using the command
sudo systemctl restart ssh.
With these steps, you’ll have a secure SSH connection to your Raspberry Pi, allowing you to manage your IoT devices remotely without worrying about unauthorized access.
