encryption was implemented back in 2010 as a default option, for users sending and checking their email starting today. According to Google, this means that no one will be able to listen in if using Gmail on public Wi-Fi, phone, tablet, or computer.
If that weren’t enough, Gmail security engineering lead Nicolas Lidzborski revealed that all emails will be encrypted saying, “In addition, every single email message you send or receive—100 percent of them—is encrypted while moving internally. This ensures that your messages are safe not only when they move between you and Gmail\'s servers, but also as they move between Google\'s data centers—something we made a top priority after last summer’s revelations.”
The implementation of the encrypted emails is good news for those wishing for privacy from agencies such as the NSA. However, last August it was reported that Google had been accused of scanning Gmail users’ email messages and that the company believed people have no “reasonable expectation” concerning their communications being confidential. The discovery was made when a class action lawsuit was filed against Google claiming the company “unlawfully opens up, reads, and acquires the content of people’s private email messages.”
Google’s response to these accusations was that it was “an attempt to criminalize ordinary business practices.”
