How do you generate an SSH key, add it to Github, and configure it in Ubuntu?

SSH (Secure Shell) is used to manage networks, operating systems, and configurations. It is also inside many file transfer tools and configuration management tools. Every major corporation uses it, in every data center.

Today we are gonna learn how to clone the GitHub repository or push your code to that repository through the SSH key. First of all, we need to generate a new SSH key with the following command :

ssh-keygen -t rsa -b 4096

Yoo! it's created but now you need to check where it is located. So, Go to Home Folder and then find .ssh the folder. Click Enter. ( By the way, If you can't find this .ssh folder in the Home Folder, you must have to check Show Hidden Files or Press Ctrl+H )

Here, you will see some files like this screenshot. Open id_rsa.pub with a text editor and you will see some long text ( key). Here is an example how the key looks like :

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQC3H/QMkHQooT7JFFNMT3EwY
A5Ab2VnHMJwaF4eWU29C838+vEYJqHR/6ZhPoeWC3yzAW7SvN6uMjfC6X45I

Don't copy this key by the way. You have to copy your key that you will find in your id_rsa.pub file. Then just copy (Ctrl+C) whole the thing. Now, we have to add it to our own Github Account. Let's login to our GitHub account. Then ,

Settings> SSH and GPG Keys > New SSH Key > Paste your copied key there> Add SSH Key

Here is the visualization for adding SSH key to your GitHub account -

Congratulations! Let's go... It has been done. Now you can clone any repository, push your code to your repository, etc. Try it out right now!
