SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)
Create a repo.
Make sure there is at least one file in it (even just the README.md)
Generate a SSH key pair (private/public):
1
ssh-keygen -t rsa -C "your_email@example.com"
or even better:
1
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
Copy the contents of the public SSH key
macOS:
1
pbcopy < ~/.ssh/id_rsa.pub
GNU/Linux (requires the xclip package):
1
xclip -sel clip < ~/.ssh/id_rsa.pub
Windows Command Line:
1
type %userprofile%\.ssh\id_rsa.pub | clip
Git Bash on Windows / Windows PowerShell:
1
cat ~/.ssh/id_rsa.pub | clip
or ofcourse copy it via your favorite editor, cat, or whatever suits your needs :)
Copy the public SSH key to GitHub
Copy the contents of the to your SSH keys to your GitHub account settings (https://github.com/settings/keys).
Test the SSH key:
1
ssh -T git@github.com
Change directory into the local clone of your repository (if you’re not already there) and run:
1
git remote set-url origin git@github.com:username/your-repository.git
Now try editing a file (try the README) and then do:
1
2
3
git add -A
git commit -am "Update README.md"
git push
You should not be asked for a username or password. If it works, your SSH key is correctly configured.
