Setup SSH Authentication for Git Bash on Windows

Setup SSH Authentication for Git Bash on Windows

Prepararation

  1. Create a folder at the root of your user home folder (Example: C:/Users/username/) called .ssh.
    You can run something like: mkdir -p ~/.ssh
  2. Create the following files if they do not already exist (paths begin from the root of your user home folder):
    • touch ~/.ssh/config
    • touch ~/.bash_profile
    • touch ~/.bashrc

Create a New SSH Key

Follow the steps in the section named "Generating a new SSH Key" found in the following documentation from GitHub: Generating a new SSH key and adding it to the ssh-agent

Configure SSH for Git Hosting Server

You can use your favorite text editor: nano, vim, subl, atom, code
For example, run code ~/.ssh/config

Then, add the following lines to .ssh/config which should be found in the root of your user home folder:

AddKeysToAgent yes
Host github.com
 Hostname github.com
 IdentityFile ~/.ssh/id_rsa

Enable SSH Agent Startup Whenever Git Bash is Started

Run your editor, e.g. code ~/.bash_profile and add the following lines:

test -f ~/.profile && . ~/.profile
test -f ~/.bashrc && . ~/.bashrc

Run your editor, e.g. code ~/.bashrc and add the following snippet:

# Start SSH Agent
#----------------------------

SSH_ENV="$HOME/.ssh/environment"

function run_ssh_env {
  . "${SSH_ENV}" > /dev/null
}

function start_ssh_agent {
  echo "Initializing new SSH agent..."
  ssh-agent | sed 's/^echo/#echo/' > "${SSH_ENV}"
  echo "succeeded"
  chmod 600 "${SSH_ENV}"

  run_ssh_env;

  ssh-add ~/.ssh/id_rsa;
}

if [ -f "${SSH_ENV}" ]; then
  run_ssh_env;
  ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
    start_ssh_agent;
  }
else
  start_ssh_agent;
