Apple has thrown its weight behind encrypting the web, encouraging iOS developers to make encryption the default for their apps.

Among the privacy features Apple announced at its worldwide developer conference last week was an important endorsement of encrypting the web by making all websites and apps, HTTPS by default.

Apple is using iOS 9 to influence iOS developers to make their apps encrypted by-default.

“If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible,” Apple explains in its pre-release documentation for iOS 9.
