SSH Key Setup for Raspberry Pi
SSH keys provide a secure way to authenticate and access Raspberry Pi remotely without using passwords. Here’s how to set up SSH keys on Raspberry Pi:
Step 1: Generate SSH Keys
Use the following command to generate SSH keys on your local machine:
ssh-keygen -t rsa -b 4096
This command creates a public and private key pair. Save the keys in the default directory or specify a custom location.
Step 2: Copy the Public Key to Raspberry Pi
Use the following command to copy the public key to your Raspberry Pi:
ssh-copy-id pi@raspberrypi.local
Replace "pi" and "raspberrypi.local" with your Raspberry Pi’s username and hostname or IP address.
Step 3: Test the Connection
Test the SSH connection using:
ssh pi@raspberrypi.local
If the setup is successful, you’ll be logged in without entering a password.
