#Yubikey (and Any Other Smartcard) SSH Connection shortcuts
In Windows envionment, not everything works out of the box especially about Yubikey. So you need to install additional tools and take additional steps.
Because of a bug, in Windows, when you unplug your smart card and re-plug, it may not run always.
These gists are simple batch commands to reset the state of gpg4Win to make your smart card available again with simple clicks, and without restarting your PC.
You may also want to create a new shortcut for gpg-connect-agent and run it on startup:
"C:\Program Files (x86)\GNU\GnuPG\gpg-connect-agent.exe" /bye
