Generating SSH Keys
SSH, or secure shell, is a secure protocol and the most common way of safely administering remote servers. It’s important to understand how SSH is used for authentication with Git and similar tools.
I have multiple accounts in Github and Bitbucket for the usage of work and personal. So I had to set up multiple SSH keys on a single machine.
$ ssh-keygen -t rsa -C "public.hodoo@gmail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/davidlee/.ssh/id_rsa): /Users/davidlee/.ssh/id_rsa_github
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/davidlee/.ssh/id_rsa_github.
Your public key has been saved in /Users/davidlee/.ssh/id_rsa_github.pub.
# Mac
$ pbcopy < ~/.ssh/id_rsa_github.pub
Set a config file
# ~/.ssh/config
Host hodoogithub
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_github
Let’s connect!
$ ssh -T git@hodoogithub
Hi hodoolee! You've successfully authenticated, but GitHub does not provide shell access.
Set a remote-url
$ git remote set-url origin git@hodoogithub:hoodoolee/project.git
