Generate SSH key on Ubuntu

ssh-git-github.md

Here's a simplified guide to generate an SSH key on Ubuntu and link it with Git and a GitHub profile:

1. Generate SSH Key:

   ssh-keygen -t rsa -b 4096 -C "[email protected]"

   When prompted, press Enter to accept the default file path and filename.

2. Start the SSH Agent and Add Your Key:

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

3. Display the SSH Key:

   cat ~/.ssh/id_rsa.pub

   This will display your public SSH key in the terminal. Manually select the content and copy it using your mouse or terminal's copy function.

4. Link SSH Key to GitHub:

   • Go to GitHub and log into your account.
   • Click on your profile picture in the top right corner, and then click on Settings.
   • In the left sidebar, click on SSH and GPG keys.
   • Click the New SSH key button.
   • Paste your copied SSH key into the "Key" field.
   • Give it a meaningful title and then click Add SSH key.

5. Test the Connection:

   ssh -T [email protected]

   If everything went well, you should see a message saying that you've successfully authenticated.

6. Configure Git (if not done before):

   git config --global user.name "Your Name"
   git config --global user.email "[email protected]"

That's it! You've generated an SSH key on Ubuntu, linked it to Git, and associated it with your GitHub profile.
