I use a Yubikey to store a GPG key pair and I like to use this key pair as my SSH key too. GPG on Windows exposes a Pageant style SSH agent and I wanted a way to use this key within WSL2.
- Run
sudo apt-get install socat
- Download and Copy the
wsl2-ssh-pageant.exe
to your $HOME/.ssh directory - Add the following to your
.bashrc
or.zshrc
:
export SSH_AUTH_SOCK=$HOME/.ssh/agent.sock
ss -a | grep -q $SSH_AUTH_SOCK
if [ $? -ne 0 ]; then
rm -f $SSH_AUTH_SOCK
setsid nohup socat UNIX-LISTEN:$SSH_AUTH_SOCK,fork EXEC:$HOME/.ssh/wsl2-ssh-pageant.exe >/dev/null 2>&1 &
fi
export GPG_AGENT_SOCK=$HOME/.gnupg/S.gpg-agent
ss -a | grep -q $GPG_AGENT_SOCK
if [ $? -ne 0 ]; then
rm -rf $GPG_AGENT_SOCK
setsid nohup socat UNIX-LISTEN:$GPG_AGENT_SOCK,fork EXEC:"$HOME/.ssh/wsl2-ssh-pageant.exe --gpg S.gpg-agent" >/dev/null 2>&1 &
fi
Some of the code is copied from benpye's wsl-ssh-pageant. This code shows how to communicate to pageant.
