The best way to protect the data on your storage devices is to use encryption software. This guide will demonstrate how to securely encrypt a USB flash drive with Windows or Mac so that the data stored on it cannot be read nor accessed without entering a secure password.
This is crucial if your USB or Flash drive stores sensitive or personal information. Thumb drives have become increasingly important when we need to store data. If these devices happen to be stolen, you can make sure the person with the right encryption key can access the information.
USB drives are incredibly convenient for storing and transferring files, but their portability is both a benefit and a security risk. Since USB drives are small and easily transportable, they can easily be lost or stolen. If an encrypted USB drive falls into the wrong hands, the data is protected and inaccessible without the encryption key. On the other hand, an unencrypted USB drive can expose sensitive personal, financial, or business information if it’s lost or stolen. Encryption is the process of encoding data so that only authorized parties can access it. In simple terms, encryption turns your data into unreadable code, which can only be decrypted with the correct password or encryption key. Whether you’re a business professional, student, or individual user, encrypting your USB drive is a simple yet effective way to ensure that your sensitive information remains private, even in the event of loss or theft.
The most significant benefit of encryption is its ability to prevent unauthorized access. Without the correct password or encryption key, encrypted data remains unreadable and inaccessible. If a USB drive is lost or stolen, the encryption ensures that the thief will not be able to open or extract any of the files. Even if the drive is plugged into a computer, the encryption will prompt the user for the password, making it virtually impossible for anyone without authorization to gain access.
For businesses and professionals who handle personal or sensitive data, encryption can help ensure compliance with privacy regulations such as the GDPR (General Data Protection Regulation), HIPAA (Health Insurance Portability and Accountability Act), or other data protection laws.
In an increasingly connected world, privacy is more important than ever. Personal information, confidential business documents, and sensitive data (such as financial records, health information, or intellectual property) are often stored on USB drives. If these files fall into the wrong hands, they could be misused, sold, or exposed, leading to privacy breaches, identity theft, or financial loss. By encrypting your USB drive, you ensure that your personal and professional data remains private and secure. Even if the drive is intercepted, without the decryption key, it’s virtually impossible for unauthorized individuals to access the data, thus ensuring confidentiality and protecting your privacy.
Data breaches can occur in various ways, such as hacking, lost devices, or human error. If a USB drive is unencrypted, the risk of a data breach increases significantly because anyone with physical access to the drive can easily access the stored files. This is especially concerning for businesses that handle sensitive client information or confidential projects.
macOS has built in USB encryption features, which lets you encrypt and decrypt USB drives and other storage media.
Use "Finder" to encrypt USB drives on MacBook. With macOS Mojave, you can easily encrypt and decrypt generic mass storage devices using Finder.
Note: Using Finder to encrypt will restrict the usage to macOS only. You will not be able to access the data with Windows or Linux.
To access the thumb drive, you only need to input the password that you created earlier
Keep in mind, there is no way to reset this password
Note: If you do not see the Encrypt option when you right-click the thumb drive. This means that the USB storage device is not in the proper format to use the baked-in macOS encryption. You may need to access your data from a Windows PC or a Linux machine. If so, you will want to opt for a third-party encryption solution. A couple of high-quality options are Disk Cryptor and VeraCrypt.
BitLocker is a full volume encryption feature included with Microsoft Windows (Pro and Enterprise only) versions starting with Windows Vista. If you do not have Bitlocker you can download it here
Using BitLocker: (Windows 7-10)
1) Connect your USB drive
2) Open the File Explorer and find your USB drive
3) Right-click on the USB dive and click "Turn on BitLocker"
4) BitLocker will start and ask: "Choose how you want to unlock this drive," click the checkbox "Use a password to unlock the drive"
5) Enter a good password - twice
6) You will be asked, "How do you want to back up your recovery key?" Either save it to a file or print it, or both
7) Choose "Encrypt used disk space only" (if you already have files on it), or choose "Encrypt entire drive" (if the drive is blank)
8) Click "Compatible Mode" so you have the maximum compatibility with other devices and computers
9) Select "Start encrypting". Do not remove your USB drive until you see the message stating encryption is finished
When you connect your flash drive again, you will be prompted to enter the password you selected. Note: You will not be able to use this drive on a computer that does not have BitLocker installed.
The "Executable" for decryption cannot be hidden behind the encryption software. To make sure this does not happen, you will need to partition the USB drive. This will store the encryption software on the unencrypted partition. In this way, no matter which computer or device you go to with your USB drive, you will be able to run the encryption program from that drive
Note: You will be restricted to having access to that particular software from computers running the same Operating Systems with which the encryption software is compatible.
Most all USB stick encryption programs will perform the partition process for you. If you want your data to be truly portable and accessible from all operating systems. Then the only way you can ensure complete compatibility is to partition the USB and create several copies of your data. Making each partition encrypted in a format that is compatible with each operating system. Example would be a copy for Windows, a copy for macOS, a copy for Linux, for Google Android OS, Red Hat Enterprise Linux OS, Darwin OS, FreeBSD OS, Oracle Solaris OS, SunOS, UNIX OS. As you can see, the list could get very long.
If you don’t have access to BitLocker (i.e., using Windows 10 Home), you can use third-party encryption software.
Below is a list of USB encryption software, which includes free and paid programs. You can load the software on your USB drive along with the encrypted data, avoiding most all software restrictions on the devices that you connect to.
You do not have to install VeraCrypt on your device. You can download it directly to your USB drive. But VeraCrypt does require the presence of the Windows, mac OS X, or Linux operating system in order to run. VeraCrypt creates two levels of security. You can have a hidden vault for your real data, which will be protected by one password, and then a visible vault that will be protected by a different password. This visible vault is called the “outer volume.” Its purpose is to protect your hidden data should someone try to force the password out of you. When you connect the USB stick to your computer, it will show up in Windows Explorer, but you can only see the VeraCrypt program and the decoy vault.
AxCrypt is a free, open source and GNU GPL-licensed encryption tool that is simple, intuitive, and efficient. The best part of this tool is its integration with the Windows shell. One can easily encrypt a USB drive by right-clicking and selecting the option “AxCrypt.” Another interesting feature of this tool is the "Timed Execution". You can encrypt the file for a set period of time and set it to un-encrypt automatically. It also has a feature to resist brute force attacks. AxCrypt also has decryption apps for Android and iOS so that you can open encrypted files on your smartphone as well.
SecurStick will encrypt your USB drive for computers running Windows, macOS, and Linux. This multi-platform support makes SecurStick almost unique in the world of USB memory device encryption. The program creates a “Safe Zone”. This is the encrypted vault. And it does not need to occupy the entire storage space of the drive. Once you have set up the Safe Zone, you just copy files into it through your device. The Safe Zone will also expand as files are added. Encryption is performed with the AES cipher using a 256-bit key. The flexibility to connect to Windows, macOS, or Linux means that SecurStick’s usability is another great encryption system.
USB Flash Security is a product of Japanese developer Kashu System Design Inc. This software is available in both paid and free versions. You can use the program for free for personal use. The free version has a data limit, so you can only protect up to 4 gb of data. The utility has four prices, each with a higher data storage limit and allowing use on multiple memory sticks. The most expensive version has a data limit of 2000 gb and a device allowance of three USB memory sticks. The program encrypts the entire USB stick, except for a small space that stores the unlocking program. Once this program is active, you will only see the executable file for the program, all other files are hidden. You can only use with Windows computers.
