WARNING: UNPROTECTED PRIVATE KEY FILE!

If you are getting this error when you try to SSH in to your computer, then you probably reset the permissions on your hidden .ssh directory in your user folder, and now your keys are not secure. It is important that these files not be writable by everyone with a login to your computer, so openssh will give you an error if you try to use them.
