yubiswitch is an OSX status bar application to enable/disable a Yubikey Nano from Yubico.

Yubikey is the producer of the Yubikeys: an hardware authentication device, designed to provide an easy to use and secure compliment to the traditional username and password.

By touching the exposed gold edge, a YubiKey Nano emits a One Time Password (OTP) as if it was typed in from a keyboard. The unique passcode is verified by a YubiKey compliant application.

So far all looks great doesn't it? :D

Whooops! You see? I brought my laptop (lid opened) with me for a walk to a meeting room holding it with my right hand touching the golden stripe and this caused the Nano to start sending random OTP passwords to my Vim session, and to the FB chat window I had opened with my wife, and right now she's been asking WTF I've been writing :P

This status bar app allows you to avoid sending those accidental OTP passwords by allowing you to enable or disable the yubikey using a convenient global keyboard hot key that you can configure yourself.

Download the latest version in DMG format from github release page here.

The application supports two basic AppleScript commands:

• KeyOn
• KeyOff

You can switch your yubikey on and off using this basic osacript commands:

$ osascript -e 'tell application "yubiswitch" to KeyOn'

$ osascript -e 'tell application "yubiswitch" to KeyOff'

Menu items in the status bar:

Preference window:

• This applicaiton only works with a single model of yubikey, the YubiKey Nano. There is no need to deal with other yubikeys because their form factor doesn't encourage the users to leave it always plugged in. The nano is the only the model that fits cleanly into your usb port. It has idVendor 0x1050 and idProduct 0x0010.

• This app only works with recent version of OSX because it relies on the Notification Centre. OSX 10.8.x and above would do it. Sorry about that.

• Make hotkey configurable via configuration window, currently it's static and it is cmd-Y. (This is done via ShortcutRecorder now)

• Use NSNotificationCenter to notify other classes (ie AppDelegate and YubiKey) when user preferences are changed

• Add "Start at login" feature

• Support for basic AppleScript comomands: KeyOn/KeyOff

• Feature: lock computer when yubikey is removed (use IOServiceAddMatchingNotification in IOKit?)

• Feature: check update features, check if current version is the latest. Connect to github somehow

• Support more yubikeys nano on multiple USB slots

• Better support for plug and unplug events

• Convert release process using [github's Release APIS] (https://github.com/blog/1645-releases-api-preview) and ChocTop

Note that this will change soon to be integrated with [github's Release APIS] (https://github.com/blog/1645-releases-api-preview)

When you want to create a release:

• Tag repo with vx.y, ie git tag -a -m 'comment' v0.2
• Compile release app bundle in Xcode
• Run script: cd dmg/ && bash createdmg.sh
• Get the file at /tmp/yubiswitch\_$VERSION.dmg and distribute via release page as explained in the github blog

yubiswitch uses ShortcutRecoder to implement global hot key and shortcuts recording in the the preference window.

• ShortcutRecorder is at : https://github.com/Kentzo/ShortcutRecorder
• I'll need to add it to your yubiswitch clone using git submodule using command:

git submodule add git://github.com/Kentzo/ShortcutRecorder.git

• See this helpful page for instructions on how to set up your Xcode environment should you have any problem.

Credits to Anton Tolchanov (@knyar), he originally wrote this in Python using PyObjC bridge. I decided to port this into Objective-C to learn the language when I found out that Carbon Event Manager libs have been removed from Python3. See http://docs.python.org/2/library/carbon.html
