GitHub SSH Auth/Signing

• Using MinTTy on windows, so environment variables might be different from your existing windows setup.
• Guide meant for windows, but should-not be any different in Linux, just ignore the powershell comands.

1 - Set Working Directory

cd ~/.ssh

touch config

2 - Creating & Adding Key

Generate Key

ssh-keygen -t ed25519 -C "[email protected]"

In Powershell

Get-Service -Name ssh-agent | Set-Service -StartupType Automatic (Elevated Command)

Start-Service ssh-agent

Then on Bash

eval "$(ssh-agent -s)"

OR if want to continue in powershell, just do

ssh-add C:\path\to\your\key

Then, to verify changes do

ssh-add -l

add .pub keys to GitHub, for Auth and Signing if want to sign using same key as well

3 - Configuration

~/.ssh/config

Host OTonGitHub
  HostName github.com
  User git
  IdentityFile ~/.ssh/OTonGitHub
  AddKeysToAgent yes
  IdentitiesOnly yes
# LogLevel INFO | DEBUG
# Port 22

Test Configuration

ssh -T git@OTonGitHub

Set username and email

git config --global user.name "OTonGitHub"

git config --global user.name [email protected]

• quotes not necessary for email

4 - Signing Commits

• First test if it works or not already.
• IF private email is disabled, just unset email, and make sure all staged commits don't contain private email.

git config --global --unset user.email

IF staged commits contain private email, change it to provided no-reply email.

git commit --amend --author="OTonGitHub <[email protected]>" --no-edit

• Finally, enable signing commits, (to get rid of unverified commits)

git config --global --unset gpg.format (skippable)

git config --global gpg.format ssh

git config --global user.signingkey ~/.ssh/OTonGitHub.pub

git config --global commit.gpgsign true

4 - Adding Repository

New Repository

echo "# ProjectName" >> README.md
git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin [email protected]:OTonGitHub/rgwegergewgwerg.git
git push -u origin main

Push from an Existing Repository

git remote add origin [email protected]:OTonGitHub/rgwegergewgwerg.git
git branch -M main
git push -u origin main
