Mozilla Thunderbird recently integrated OpenPGP right into the main application. No add-ons are needed for email privacy. OpenPGP’s world-class encryption is easy to set up and use without additional software. Thunderbird and OpenPGP Version 78.2.1 of the Thunderbird email client has support for end-to-end encryption (e2ee) built right in. This integration means you no longer need add-ons like Enigmail . Thunderbird uses OpenPGP for encryption, which is a free, nonproprietary protocol. Based on the freeware versions of Phil Zimmerman’s Pretty Good Privacy (PGP), it’s now very much its own thing. Thunderbird’s OpenPGP integration allows you to encrypt a message. Then, only the people you want to read your message will be able to do so. It also lets you digitally sign a message so your recipient can be confident the message hasn’t been altered in transit. OpenPGP uses the principle of pairs of public and private (or “secret”) encryption keys. To use OpenPGP, you … [Read more...] about How to Use OpenPGP Encryption for Emails in Thunderbird

End-to-end encryption (E2EE) ensures that your data is encrypted (kept secret) until it reaches an intended recipient. Whether you’re talking about end-to-end encrypted messaging, email, file storage, or anything else, this ensures that no one in the middle can see your private data. In other words: If a chat app offers end-to-end encryption, for example, only you and the person you’re chatting with will be able to read the contents of your messages. In this scenario, not even the company operating the chat app can see what you’re saying. Encryption Basics First, let’s start with the basics of encryption. Encryption is a way of scrambling (encrypting) data so that it can’t be read by everyone. Only the people who can unscramble (decrypt) the information can see its contents. If someone doesn’t have the decryption key, they won’t be able to unscramble the data and view the information. (This is how it’s supposed to work, of course. Some encryption systems have security flaws … [Read more...] about What Is End-to-End Encryption, and Why Does It Matter?
The power supply (PSU) is a critical part of any PC. It powers all the components in your PC, and a bad or faulty one can bring everything down. Here’s what to look for in a power supply while putting together a PC. A PSU Is a Critical Piece of PC Infrastructure When we turn on a light, open a faucet, or walk down a nicely paved street, we don’t often think about the wondrous infrastructure making all that possible. But if somebody hadn’t taken the time to think about it, things wouldn’t be so wondrous. It’s the same when building a PC. We get obsessed with how many cores a CPU has or the number of compute units in a GPU . But rarely do we think twice about the power supply unit (PSU,) which provides power to everything else in your PC. You don’t need to think about your power supply too much, of course. But, if you don’t consider the PSU at all, there’s a good chance you’ll be thinking about it a lot once it starts causing problems. If your computer doesn’t get … [Read more...] about How Important Is the Power Supply (PSU) When Building a PC?
VPNs and Incognito Mode are two of the most popular tools for online privacy. A VPN makes you harder to track while browsing, while Incognito Mode gives you a fresh browser that doesn’t remember your history—and won’t give you away to websites while browsing on the VPN. What Is Incognito Mode? Private browsing has a lot of names, including InPrivate in Microsoft Edge and Incognito Mode in Google Chrome. Its purpose is to give your browser temporary amnesia. Whenever you’re in incognito mode, the browser will not store the data of the sites you visited: no addresses, no cookies, none of the data you entered, nothing. Incognito Mode also gives you a fresh browser state without any cookies. So, if you’re logged in to Facebook in your normal browser window, you can open an Incognito Mode window and Facebook won’t see you as logged in while you browse with that window. When you browse in Incognito Mode, nothing you do in your browser will be remembered by your browser itself. … [Read more...] about What’s the Difference Between Incognito Mode and a VPN?
Did you know that laptops and other devices without GPS hardware can determine your precise physical location—with just a Wi-Fi radio? Here’s how this often-overlooked feature of modern “Location Services” works. “Location Services” Is More Than GPS Modern operating systems—including iOS, iPadOS, Android, Windows 10, macOS, and Chrome OS—have their own “Location Services” systems built in. When an app—like a map or navigation app, for example—wants to request your location, it doesn’t just access your device’s GPS radio directly. Instead, it asks your operating system’s “Location Services” where you are. Modern Location Services systems use a variety of techniques to find your location. GPS is one of those techniques. But, when a GPS signal or GPS hardware is unavailable—or just too slow—Location Services has other tricks up its sleeve. For example, if your device has a cellular signal, it may triangulate your location based on signals from cellular towers. Based on the … [Read more...] about How Devices Use Wi-Fi to Determine Your Physical Location
