SSH for remote git repos

git, ssh

Introduction

There are different ways to connect to a remote git repository like GitHub, CodeBerg, GitLab, etc:

  • HTTPS
  • SSH

HTTPS is for beginners and for casual coding and SSH on the other hand is more secure, easy to work with and used by professionals and few beginners.
The setup is fairly easier and once setup is really easy to work with.

Setup

Step 1: Generate a ssh key

ssh-keygen -t ed25519 -a 100 -f ~/.ssh/git -C "git@tspamiitesh@gmail.com"

Step 2: Start the ssh agent

eval "$(ssh-agent -s)" # Depends upon the shell
ssh-add ~/.ssh/git

Step 3: Add ssh public key to GitHub

cat ~/.ssh/git.pub

Then,

  • Open GitHub (or any remote git service) → Settings
  • Go to SSH and GPG keys
  • Click New SSH key
  • Paste the key
  • Save

Step 4: Test the ssh connection

ssh -T git@github.com

Step 5: Config File

Host *
    AddKeysToAgent yes
    IdentitiesOnly yes
    PreferredAuthentications publickey

Host github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/git

The above configuration is a really basic one and you can add up on many other features

This is one of the most simplest ways to setup ssh
