SSH tools setup using Yubikey in windows



Note: Only public key is needed


Download and install GPG4win (Currently 3.1.4)


Import the public key using Kleopatra or gnupg tools
Gpg --import etc.
run: gpg --card-status this will fill the private key stubs


Convert the public key to SSH format
gpg --export-ssh-key titasraha@hotmail.com > c:\users\traha\Downloads\sshpubkey.txt


Append the ssh public key to authorized_keys section under <userhome>/.ssh


Use putty to connect leaving the key file location blank


Enable GPG4Win and Putty SSH hook
Open %APPDATA%\gnupg\
Comes out to C:\Users\{user}\AppData\Roaming\gnupg
Create/Edit file gpg-agent.conf
Add Line
enable-putty-support


Connect agent commands useful in case of problem with the card
To Start up (bye means start the agent but close the window)
"C:\Program Files (x86)\GnuPG\bin\gpg-connect-agent.exe" /bye


To force shutdown:
"C:\Program Files (x86)\GnuPG\bin\gpg-connect-agent.exe" killagent /bye
