Introduction

Difference between HTTP, HTTPS and SSH links

HTTP: Stands for Hypertext Transfer Protocol. That isn't safe. Since information delivered over HTTP is sent in plain text, hackers can intercept and alter it.

HTTPS: Stands for Hypertext Transfer Protocol Secure. All communications between the user's browser and the website are encrypted if a URL loads using the HTTPS protocol.

SSH: Stands for Secure Shell. Provides encryption for data in transit and also includes authentication for both the client and the server. Used for secure remote access to servers (SSH login)

SSH Keys in GitHub

Need for SSH Keys

You'll frequently need to authenticate yourself to GitHub using your username and password while interacting with a GitHub repository. An SSH key is a backup identity that you can use instead of constantly entering your password and username.

SSH keys are saved in pairs: a private key that is kept on your computer alone and a public key that is shared with services like GitHub. As long as the keys match, you get in.

Nobody will be able to reverse engineer your private key from the public one thanks to the cryptography used in SSH keys.

Steps to generate an SSH key pair

Step1: Navigate to GitHub settings

Step2: Click on SSH and GPG keys

Step3: Click New SSH key, it will open a window asking key title and the key

Step4: Now open your terminal paste the below command

          ssh-keygen -t ed25519 -C "[email protected]"

Step5: It will ask for the file where the key needs to be stored, if we click enter then it will take a default location

Step6: Click enter twice

Step7: In this step the public and private key will be generated and it will show you the location where it is stored.

Step8: We can navigate to that path and find the public and private key in our system. Open the file ***.pub and copy the public key generated

Step9: Paste the public key in the GitHub window and give a key title

Step10: We are done and ready to go!
