Configuring private github repo with additional ssh key

Recently, i found that for some cases that you might want to commit to private github repo with additional ssh key can be tricky. I googled for a solution and found this one is quite effective. All you need to do is share ssh key to github repo and config your ssh config file to choose an additional ssh key as ssh identity.

Step 1 - Create an additional ssh key

ssh-keygen -t rsa -b 4096 -C "[email protected]" -f ~/.ssh/<filename>


ssh-keygen -t ed25519 -b 4096 -C "[email protected]" -f ~/.ssh/<filename>

Step 2 - Add origin to your local copy

git remote remove origin
git remote add origin [email protected]:<github_user>/<repository>.git

Step 3 - Config ssh config

Host <repository>
	User git
	IdentityFile ~/.ssh/<filename>
    IdentytiesOnly yes

With these three steps,your local copy should be able to collaborate with preivate repository.
