Here are the steps to configure your SSH Key with Github & communicate easily with your repositories.

Step 1

First of all check whether you have created any public SSH keys in your computer.

ls -al ~/.ssh

Check the output you get & if you find any file named with, id_dsa.pub / id_ecdsa.pub / id_ed25519.pub / id_rsa.pub

You don’t have to worry about generating the public SSH Key again. Skip the 2nd step & go to the 3rd step if you already have a public SSH Key.

Step 2

To Generate public SSH Key, Copy and paste the below command to your terminal.

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Enter your email address inside double quotation.

Make Sure that you use default settings for following option, just press Enter to continue.

Enter file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]

Then enter a passphrase, just press Enter to continue.

Enter passphrase (empty for no passphrase): [Type a passphrase]
# Enter same passphrase again: [Type passphrase again]

Finally you’ll be able to see the files that automatically created for public SSH Key.

Make sure that you start ssh agent in background by following command.

eval "$(ssh-agent -s)"

Then add the public key to ssh agent

ssh-add ~/.ssh/id_rsa

Finally copy the public key to clipboard by,

pbcopy < ~/.ssh/id_rsa.pub

Then go to Github Settings SSH Page and add your copied SSH Key.
