Encrypted disk images are highly secure, and you can use them to send files to anyone who uses a Mac, as long as you can give them the password they need to access the files. Naturally, you don’t want to send this password via email, but you could send it by a messaging app that supports encryption, such as Messages, Signal, Slack, or others. Aug 06, 2021 This page includes 5 best PC encryption software for both Windows and Mac users to free download. Follow this page and apply a favored PC encryption software to safely encrypt your computer hard drives, locking files and folders for safety consideration now.
FileVault is one of those Mac features that you know is there but are never really sure what it’s there for. Apple has never really made a big song and dance about how the feature protects your data or why you should bother with it, so we’re going to do it instead.
AESCrypt is a free and open source software that enables you to encrypt files and folders. It works with Windows, Android, MacOS, iOS, Linux, and Python. It uses 256-bit AES encryption to secure data and is very easy to use. This one is ideal if you only need to encrypt a few select files. Any new files that you create are automatically encrypted as they are saved to your startup disk. When FileVault setup is complete and you restart your Mac, you will use your account password to unlock your disk and allow your Mac to finish starting up.
This won’t be a literal song and dance, unfortunately, (we don’t have the natural rhythm) but we will tell you all you need to know about FileVault, as well as how and why you should use it. But feel free to sing the words as you read them and dance along at the same time.
Okay, let’s get into it.
What is FileVault?
FileVault is macOS’s built-in disk encryption feature. It's designed to encrypt your Mac's hard drive and all of the files located on the drive using 128-bit AES encryption with a 256-bit key.
Once FileVault is enabled on your Mac, all existing data will be encrypted. From then on, any new and changed data will be automatically locked down and password protected on boot to prevent unauthorized access.
FileVault was originally introduced to Mac back in 2003 on OS X 10.3 Panther. But to say it wasn’t very good would be an understatement. It was terrible. The functionality was poor, the implementation was shoddy, and only the home directory could be encrypted.
Thankfully, 2003 was a long time ago and now, with FileVault 2, you can expect full-disk encryption and the ability to use the Find My Mac feature to wipe your drive remotely if ever your system falls into suspect hands.
Should I use FileVault?
Yes, is the short answer.
If you’re concerned about the privacy of your files and user data, and your computer contains information that shouldn’t be seen without authorized access, you should absolutely use FileVault disk encryption.
The feature is particularly good if you’re a MacBook user that regularly takes your laptop on the move where there’s a greater chance of it becoming lost or misplaced.
FileVault offers peace of mind and that counts for a lot. There are, however, reasons why you might not want to bother with the feature.
First of all, FileVault enforces a password. If you struggle to remember passwords (it’s well worth using a password manager if you do) or prefer using your Mac without one, you might consider FileVault to be more effort than it’s worth.
Secondly, FileVault encryption is backed into the CPU which can affect performance. If you own a newer SSD-equipped Mac you’re unlikely to notice the difference, but in older Macs with HDDs performance can take a significant hit — enough for you to consider using your computer without encryption.
How to check if FileVault is enabled?
In systems running OS X Yosemite 10.10 and newer, Apple encourages you to turn on FileVault 2 during setup. So, if you’re using a newer Mac, there’s every chance that your files are already being encrypted.
Here’s how to check:
- Click on the Apple menu and select System Preferences.
- Select Privacy & Security.
- Click on the FileVault tab and the status will be displayed.
Before you turn on FileVault, be aware that the initial encryption process can take hours. However, it does run in the background so you can continue using your Mac as normal, albeit not at peak levels of performance.
Also, FileVault encrypts the entire disk. Any additional users will need to be enabled so that they can unlock the disk by entering their password.
How to turn on FileVault disk encryption
- Click on the Apple menu and select System Preferences.
- Select Privacy & Security.
- Click on the FileVault tab, then click the lock in the bottom left corner of the window.
- Enter your administrator name and password and click Unlock.
- Click Turn On FileVault.
- Choose whether you want to link your iCloud account to FileVault to unlock the disk and reset your password or create a recovery key and click Continue.
- Click Restart to reboot your Mac and begin the encryption process.

Choosing a FileVault Recovery Key
The FileVault recovery key deserves special mention here. If you choose this option over linking your iCloud account, it’s critical that you make a note of the recovery key and keep it in a safe place that’s not on your hard drive. Losing the recovery key makes your data unrecoverable so it’s worth writing it down and storing it in a safe place, as well as entering it into a password manager.
How do I turn off FileVault?
Once your disk has been encrypted you can turn off FileVault at any time. You might decide to do this if you find that the feature is too resource-heavy or this particular level of security isn’t for you.
- Click on the Apple menu and select System Preferences.
- Select Privacy & Security.
- Click on the FileVault tab, then click the lock in the bottom left corner of the window.
- Enter your administrator name and password.
- Click Turn Off FileVault.
Disabling FileVault starts the process of decrypting all of your files. This runs in the background but, like encryption, is a lengthy process.
How do I keep online and offline activity private?
FileVault’s capabilities only extend as far as user data and file encryption. Other things you do on your Mac like web browsing, chatting via messaging apps, downloading software, and using files locally are not private.

Of course, in the event that your Mac is lost, for anyone to see your online and local activity they’d need to enter the admin password first. But if you share computer access and want to keep your activity private, the best option is to use an app like CleanMyMac X.
The latest edition of MacPaw’s leading utility tool comes with a Privacy feature that lets you wipe off all unwanted traces and any information that may compromise your privacy. All you need to do is choose a suitable period and let CleanMyMac X take care of the rest.

Protect your data, maintain your privacy
If there’s anything on your computer that you prefer to keep to yourself, you can safeguard your information in two simple ways:
1. Enable FileVault so that all of your user data and files are kept under lock and key.
2. Download CleanMyMac X to keep all online and local activity private.

Best File Encryption For Mac
Paranoia File & Text Encryptionconsists of two modules: File Encryptor and Text Encryptor.
Best Free File Encryption Software
- File Encryptor: Securely encrypt your private and confidential files or whole folders. The encryption/decryption process is simply done by dragging the selected file(s) or folder(s) to the application window. The application works as an archiver (a new .enc file is created).
- Text Encryptor: Keep your messages, notes, cryptocurrency keys (seeds, mnemonics), and other text information safe from unwanted readers. Use the internal database or just copy/paste to/from your favorite applications. A password is set for the current encryption/decryption session, and you may have an unlimited number of passwords for any purpose (notes, emails, social networking, communication with persons A, B, C, …).
Features:
- Provides real security - data is encrypted using strong encryption algorithms: Blowfish 448bit, AES 256bit, RC6 256bit, Serpent 256bit, Twofish 256bit, GOST 256bit (+ Threefish 1024bit and SHACAL-2 512bit for PRO Version) ciphers are available.
- Steganography: The Text Encryptor contains a steganographic feature (concealing a text within an image - JPG). A steganographic algorithm (F5 algorithm) is used in combination with chosen symmetric cipher algorithm to make a final steganogram (JPEG image).
- Fully compatible with Paranoia Text Encryption for iOS (iPhone/iPad/iPod) and Secret Space Encryptor for Android.
- A free multi platform desktop version (OS X, Windows, Linux, Solaris ...) is available on the application download page
