Git and GitHub

Tool	Version
Git	2.55.0
GitHub CLI (gh)	2.97.0

sudo dnf install git gh

Global Git config

~/.gitconfig:

[user]
    name = raioviajante
    email = 195070286+RaioViajante@users.noreply.github.com
[init]
    defaultBranch = main
[pull]
    rebase = false
[fetch]
    prune = true

The @users.noreply.github.com address keeps the real email out of commit metadata.

GitHub authentication over SSH

• Auth method: SSH (not HTTPS tokens).

• Dedicated key: ~/.ssh/id_ed25519_github (+ .pub), used only for GitHub.

• ~/.ssh/config:

  Host github.com
      HostName github.com
      User git
      IdentityFile ~/.ssh/id_ed25519_github
      IdentitiesOnly yes

Setup:

ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519_github -C "raioviajante github"
gh auth login --git-protocol ssh --hostname github.com   # upload the key
ssh -T git@github.com                                     # expect a success banner
gh auth status

Private keys never leave the machine and are not committed (.gitignore blocks id_ed25519*).
