Email was one of the earliest forms of communication on the internet, and if you’re reading this you almost undoubtedly have at least one email address. Critics today decry the eventual fall of email, but for now it’s still one of the most universal means of communicating with other people that we have. One of the biggest problems with this cornerstone of electronic communication is that it isn’t very private. By default, most email providers do not provide the means to encrypt messages or attachments. This leaves email users susceptible to hackers, snoops, and thieves.

So you want to start encrypting your email? Well, let’s start by saying that setting up email encryption yourself is not the most convenient process. You don’t need a degree in cryptography or anything, but it will take a dash of tech savvy. We’ll walk you through the process later on in this article.

Alternatively, you can use an off-the-shelf encrypted email client. Tutanota is one such secure email service, with apps for mobile and a web mail client. It even encrypts your attachments and contact lists. Tutanota is open-source, so it can be audited by third parties to ensure it’s safe. All encryption takes place in the background. While we can vouch for Tutanota, it’s worth mentioning that there are a lot of email apps out there that claim to offer end-to-end encryption, but many contain security vulnerabilities and other shortcomings. Do your research before choosing an off-the-shelf secure email app.

If you’d prefer to configure your own email encryption, keep reading.

Google has not had any of its 85,000+ employees successfully phished on their work-related accounts since early 2017, when it began requiring all employees to use physical Security Keys in place of passwords and one-time codes, the company told KrebsOnSecurity.

Security Keys are inexpensive USB-based devices that offer an alternative approach to two-factor authentication (2FA), which requires the user to log in to a Web site using something they know (the password) and something they have (e.g., a mobile device).

The US Department of Justice (DOJ) this week released the first report from its Cyber Digital Task Force – which was set up in February to advise the government on strengthening its online defenses.
The report [PDF], compiled by 34 people from six different government agencies, examines the challenges facing Uncle Sam´s agencies in enforcing the law and protecting the public from hackers. It also lays out what the government needs to do to thwart looming threats to its computer networks.

Let´s (not) Encrypt

If you´ve been following the news for the last few years it will come as no surprise that the Justice Department is not a fan of the common man having access to encryption.
The report bemoans the current state of encryption and its ability to keep the government from gathering and analyzing traffic for criminal investigations. The word ´encryption´ comes up 17 times in the report, not once in a favorable light.
In the past several years, the Department has seen the proliferation of default encryption where the only person who can access the unencrypted information is the end user, the report reads.
The advent of such widespread and increasingly sophisticated encryption technologies that prevent lawful access poses a significant impediment to the investigation of most types of criminal activity.

The demand for quantum computing services will be driven by some process hungry research and development projects as well as by the emergence of several applications including advanced artificial intelligence algorithms, next-generation encryption, traffic routing and scheduling, protein synthesis, and/or the design of advanced chemicals and materials. These applications require a new processing paradigm that classical computers, bound by Moore’s law, cannot cope with. However, one should not expect quantum computers to displace their classical counterparts anytime soon.

Ray Ozzie thinks he has an approach for accessing encrypted devices that attains the impossible: It satisfies both law enforcement and privacy purists. (?)

EFAIL furore not over yet, even though it´s easy to fix.

However, PGP´s creator Phil Zimmerman, Protonmail´s Any Yenn, Enigmail´s Patrick Brunschwig, and Mailvelope´s Thomas Oberndörfer are still concerned that misinformation about the bug remains in the wild.

Yenn tried to refute the EFAIL “don´t use PGP” on May 25, and the four have followed up with this joint post.

According to a Venafi survey of 512 security professionals attending RSA Conference 2018, sixty-four percent of respondents say their personal encryption usage has increased due to recent geopolitical changes.
