Before the operation, here are some rules you should know:

1. Make sure that there is enough power on your device.
2. You cannot access the encrypted SD card on another device even if you have the password. You need to pay attention that if you lose the original device where you encrypt SD card, you will lose the access to the files forever.
3. If your device used to encrypt the SD card is reset to factory default settings, it will be impossible to read the encrypted SD card anymore.
4. You cannot use the card during the encryption process.
5. To access the files in the encrypted SD card, you can unlock it with the password or decrypt SD card.

Now, let’s see how to encrypt SD card.
