Google is updating Gmail to allow enterprise users to send encrypted messages to any inbox in just a few clicks. Google says it’s developed a new encryption model that, unlike the current encryption feature on Gmail, doesn’t require senders or recipients to use custom software or exchange encryption certificates.

Although the encryption is for business customers, regular consumers on both Gmail and non-Gmail accounts can receive the encrypted emails.

Gmail is 21 years old today and for its birthday present it wants to give the gift of easier encryption for all. This is a service that’s aimed at companies in regulated industries to more easily encrypt their emails,
