SSH Setup Instructions

This document provides step-by-step instructions for setting up SSH keys and configuring SSH for new devices using the .dotfiles repository.

Step 1: Import the SSH Private Key

1. Securely transfer the id_ed25519 file to the new computer.
2. Place the file in the ~/.ssh directory.

Step 2: Set Correct Permissions for the SSH Key

Set the file permissions for the private key to ensure security:

chmod 600 ~/.ssh/id_ed25519

Step 3: Run Setup Scripts from .dotfiles

Execute mac_bootstrap.zsh from the .dotfiles repository to configure your environment and create a symbolic link for the SSH config file.

Step 4: Start SSH Agent and Add Your SSH Key

Start the SSH agent and add your SSH key:

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519

You will be prompted to enter the passphrase for your SSH key.

ssh-add -l

Step 5: Test SSH Connection

Test your SSH setup, for example, with GitHub:

ssh -T git@github.com

You should receive a message confirming successful authentication.

Step 6: Update SSH Key in Services

If necessary, update your SSH public key (id_ed25519.pub) in services like GitHub or GitLab.

Step 7: Final Testing

Perform operations that require SSH (e.g., Git operations) to ensure everything is configured correctly.

Notes:

• These instructions assume a Unix-like environment (Linux, macOS).
