How to password protect and encrypt the files in their portable Flash Drive, USB Hard Disk and USB SSD? This is to prevent it from falling into the wrong hands in the event you lose it, it may or may not contain personal data, given that there is nothing to lose, why not password and encrypt it?

Before they begin, it is important to know that there are 2 types of encryption for portable USB Flash Drive / HDD and SSD – hardware encryption and software encryption. The list in this article are portable software based encryption for your USB Flash Drive, if you are using Windows Vista and Windows 7: Enterprise and Ultimate editions, Windows 8 and 8.1: Pro and Enterprise editions, Windows 10: Pro, Enterprise, and Education editions, Windows Server 2008 and later, use BitLocker.

USB Password Protection Locker with Encryption For Flash Drive

BitLocker is a full disk encryption feature included with Windows Vista and later. It is designed to protect data by providing encryption for entire volumes. By default it uses the AES encryption algorithm in cipher block chaining (CBC) or XTS mode with a 128-bit or 256-bit key. CBC is not used over the whole disk; it is applied to each individual sector.

Hardware Encryption VS. Software Encryption

Software encryption options are available on the market as a cheaper alternative to hardware encryption, but the disadvantages tend to outweigh the benefits. It often requires numerous updates to keep up with hacking techniques, could be quite slow, and may require complex driver and software installations.

Software encryption also may not provide the full security that businesses are expecting, to keep sensitive information from falling into the wrong hands. Though software encryption is better than having no encryption at all, it may still be vulnerable to user error, leaving data to fall through the cracks and be susceptible to potential thieves.

Since software encryption requires users to follow certain procedures in order to secure the data, users may forget – or choose to ignore certain aspects of the encryption process.

With hardware encryption on secure USB drives, the AES encryption process is handled automatically, built right in with a small chip inside the drive itself. Once original data is encrypted, it becomes undecipherable in the background and is locked away under encrypted storage within the drive.

If a thief were to try to gain access to the data without the password, the attempt is by all practical means impossible. But once the user enters their private password, the data is decrypted instantly, and made fully available to the user.

Hardware-Based Encryption:

  • Uses a dedicated processor physically located on the encrypted drive
  • Processor contains a random number generator to generate an encryption key, which the user’s password will unlock
  • Increased performance by off-loading encryption from the host system
  • Safeguard keys and critical security parameters within crypto-hardware
  • Authentication takes place on the hardware
  • Cost-effective in medium and larger application environments, easily scalable
  • Encryption is tied to a specific device, so encryption is “always on”
  • Does not require any type of driver installation or software installation on host PC
  • Protects against the most common attacks, such as cold boot attacks, malicious code, brute force attack

Software-Based Encryption:

  • Shares computers resources to encrypt data with other programs on the computer – Only as safe as your computer
  • Uses the user’s password as the encryption key that scrambles data
  • Can require software updates
  • Susceptible to brute force attack, computer tries to limit the number of decryption attempts but hackers can access the computer’s memory and reset the attempt counter
  • Cost-effective in small application environments
  • Can be implemented on all types of media

Hardware based encryption is always the better option, all the drives in this roundup use the 256-bit AES hardware encryption required to achieve FIPS 140-2 Level 2 certification. SanDisk SecureAccess did not make it to the list because it is a software based encryption. Below are 3 hardware based encryption available worldwide.

      Hello Mitchelle,

      Mitchelle, automatic random password creation is a very dangerous feature for a data protection program to have because the possibility of someone accidentally locking their files using a random and unknown password is very high.

      It happened to me while testing your program, but fortunately the folder did not contain any important data.

      Thanks for your program but unfortunately, due to the aforementioned pitfall, I can neither use nor recommend it to anyone

      With kind regards

    Good day, Tech Nut, automatic password is the default option, you can copy it elsewhere or take screen shot using your cellphone but you can change it with your favorite password if you like. Different folders can use different password so different user can use single USB disk. Hope you try to use it again.

    Yours truly

    Kindly recommend a cross-platform (MAC, Windows) software that provides simple password-protection (not encryption) on external portable drives (HDD/SDD). From a user experience perspective, once the password-protection is activated on a portable drive on a MAC (or WINDOWS), than he/she would simply plug the drive on another laptop (MAC or WINDOWS), enter the password when prompted and read/write to the drive.

    Any suggestions would be most helpful. Thanks!
