Google wants to make it possible for you to carry your most sensitive data with you without compromising its security. Released yesterday, Secrets for Android, allows users to securely store and manage vital information like passwords, credit card, and login information.
You can’t get the app from the Android Market just yet, but you can grab a copy from the Google Code page (direct link to .apk) if you want it now. Remember to set your phone to allow for apps outside of the Android Market.
The app works best on the premise that you use a strong password (naturally) but Google also adds their own security as well. This includes automatically logging you out after inactivity and “strong encryption” on their end.
The app serves sort of a double duty purpose for aspiring Android developers in that the source code is available. Use it to learn how more on file I/O, using crypto APIs, and simple 3-D view animation.
