How to Encrypt/Decrypt SD Card in 2024

SD cards are portable storage alternatives to USB flash drives. Photographers are mostly familiar with full-size SD cards for DSLR and compact digital cameras. Many users utilize those cards to transfer photos and videos between cameras and PCs. However, you can also save documents to camera SD cards. So, they’re not just limited to storing photos and videos.  

Then there are microSD cards, which are for mobile devices. Mobile users utilize microSD cards to extend the storage of their phones or tablets. Now there are one terabyte microSD cards available for mobiles like the Galaxy S10. With a one terabyte microSD card, you’ll probably never run out of storage space for apps!

In this article, we will guide you how to encrypt SD card and how to decrypt it if forgot password.

Part 1: What Does Encrypt SD Card Mean?

Encrypting is the process of adding data protection to a device to ensure unauthorized users can’t access files saved on it. Standard encryption usually amounts to adding a password to a device. So, an encrypted SD card is one that has a password applied to it. Then nosy pokes who try to have a look through files on your encrypted storage card will need to enter the password to unlock it.

You can encrypt SD card with third-party card (drive) encryption software or built-in tools on Windows and mobile platforms. Windows 10 includes the BitLocker utility that enables users to encrypt camera SD and mobile microSD card drives with passwords. However, that utility is only available in the Windows 10 Enterprise and Pro editions. Users with Windows 10 Home will need to encrypt SD card with third-party software.

Note, however, that you can encrypt microSD cards with encryption options on Android and iOS mobiles. The good thing about those mobile encryption options is that they also restrict the cards to the devices they’re encrypted on. That means there’s no way users can utilize the cards on devices other than the mobiles they were encrypted on without reformatting (wiping) their data.

However, you’ll have to encrypt camera SD cards with Windows software or the BitLocker utility if you can. This is how to encrypt (and decrypt SD card) with the BitLocker utility in Windows 10 Pro and Enterprise.

Part 4: How to Recover Lost Data From SD Card After Decryption

If you decrypt an SD card with the Diskpart method, you might still be able to restore its lost files with Tenorshare 4DDiG. 4DDiG is the best data recovery software for Windows 10/8.1/8/7 and Mac platforms. With that software, you can restore lost image, video, audio, and document files from SD storage, hard drives, or USB sticks.

There are four alternative Tenorshare 4DDiG versions to choose from. Tenorshare 4DDiG Standard is retailing at $49.99. However, that version isn’t much different from the freeware 4DDiG, which has the same feature set. The only difference is that the freeware version is restricted to recovering one gigabyte of data. This is how you can restore lost SD card files with 4DDiG.

Step 1: Click the “First 1 GB Free” button on the 4DDiG webpage.

Step 2: Install 4DDiG with its download setup wizard.

So, that’s how to encrypt and decrypt SD card when required. Encrypting your SD storage with BitLocker is a good precaution to take if it includes any files you need to keep under wraps. Even if you never lose the SD card, encrypting it will also ensure untrustworthy colleagues can’t open its saved files. However, it’s better to encrypt microSD cards with the Encrypt SD card option on Android platforms that locks them to specific devices.
