SSH Key Pair

#osdc #opensource #ssh

SSH-Key

Accessing a remote repository via SSH without the need to provide username and password every time I pull or push.

Go to your command line prompt (e.g. the GitHub CLI installed previously), and run:

ssh-keygen

Use the same command for Windows, only with .exe extension.

Just hit Enter for each of the questions asked...
It will generate a .ssh/ directory in your home dir with key-pair inside, in the form of 2 files:
- id_rsa - is the private key - which I always keep locally on my computer
- id_rsa.pub is the public key - which I can publish somewhere on the internet

ls ~/.ssh

View and copy the contents of id-rsa.pub (depending on the OS you're using, use the appropriate editor or file viewer, here I will use Linux command cat or less. On Windows one might use Notepad).

cat ~/.ssh/id-rsa.pub

Copy the file content
Go back to your GitHub account page: Click Setting->SSH and GPG keys->New SSH key->paste the public key into the Key text box, provide some Title-> Add SSH key.
Once this is done, I will not need to provide my username and password every time I communicate with the remote repo.
This key pair might be copied over and used over several computers
