Google is moving to make queries and results from the company s immensely popular search engine encrypted by default in the coming weeks, but only for users signed into their Google Accounts.

It is unclear why Google has decided to roll secure browsing out to signed-in users only and whether or not this will eventually become the default for all Google searches.
