We use keys to lock our apartments, fences to stop the intruders, CCTV cameras to monitor our surroundings, but what about the files? In 2019, 15.1 billion records were exposed worldwide, which says a lot about the current cybersecurity situation. In this guide, we’ll show you how to encrypt files on Windows and macOS.
Files in your computer are not safe — there are numerous ways to take over your data and exploit it for wrongdoing. You can accidentally download malware that will sit silently in your computer, monitoring everything you do. Or you can insert an infected USB flash drive to a laptop without realizing it. How many times have you connected to a public Wi-Fi recently, and are you sure your sessions were safe?
You might think nothing bad will happen, but when it happens, the consequences might be very costly.
People encrypt all sorts of files, so you need to decide what is most relevant to you. Here are some ideas:
You will be able to access your files with the same password you use to log in to your computer.
File encryption is only available in the Professional, Enterprise, and Education editions of Windows — users of the Home edition are left out. However, Home users can password-protect their files on Microsoft Office applications such as Word, Excel, or PowerPoint.
While encrypting files and folders with the built-in features of macOS and Windows might seem like a good idea, it has disadvantages:
This is where NordLocker comes to the rescue. It’s an easy-to-use app that encrypts any kind of files and allows you to share them securely or upload them to the cloud. Here’s how to start:
You can encrypt an entire folder, search for sensitive files on your computer, choose them manually, or create an empty locker, where you can drag and drop files. Once the documents are in the locker, they are encrypted automatically — no further actions needed. We advise not to keep unencrypted copies of your files.
With NordLocker, sharing your files is safe and convenient: just add the email addresses of the people who are allowed to access the lockers you keep on your PC/Mac. You don’t need to send any passwords — they create their own accounts and log in with their own master passwords.
All new users get unlimited local encryption and 3GB of cloud storage for free.
