Answer 1

Step 1: First, create the SSH keys by using the following command:  

$ ssh-keygen -t rsa -C "[email protected]"

It will create both id_rsa and id_rsa.pub files for you

Step 2: Now add the id_rsa to ssh list on local computer using the following command: 

$ ssh-add ~/.ssh/id_rsa.

Step 3: After generating the keys get the pubkey using:

$ cat ~/.ssh/id_rsa.pub 

You will get something like :

ssh-rsa AAAB3NzaC1yc2EAAAADAQABAAACAQCvMzmFEUPvaA1AFEBH6zGIF3N6pVE2SJv9V1MHgEwk4C7xovdk7Lr4LDoqEcqxgeJftwWQWWVrWWf7q9qCdHTAanH2Q5vx5nZjLB+B7saksehVOPWDR/MOSpVcr5bwIjf8dc8u5S8h24uBlguGkX+4lFJ+zwhiuwJlhykMvs5py1gD2hy+hvOs1Y17JPWhVVesGV3tlmtbfVolEiv9KShgkk3Hq56fyl+QmPzX1jya4TIC3k55FTzwRWBd+IpblbrGlrIBS6hvpHQpgUs47nSHLEHTn0Xmn6Q== [email protected]

Step 4: Now all you need to do is copy this key (value) and go to github.com and under the setting (ssh and pgp key) add your public key.
