I have files that I used to copy from my SD card to my PC using the USB Mass Storage option under the "USB connection" pop-up. I checked the flag under Settings->Location & Security->Data encryption->Storage encryption and now I can't read new files of these types (e.g., .jpg and .txt files). I tried unchecking the box -- a message appeared saying that future files will be decrypted, but existing files will remain encrypted.

How do I access the files that are currently encrypted and/or decrypt them?

may be relavant: Decrypt folder, that was encrypted using EncFS, on Android. I am not sure what device you have, so i dont know if your device is using encfs (but it probably is) –  Ryan Conrad Mar 5 '12 at 17:40
Thank you for your comment. I looked at Decrypt folder, that was encrypted using EncFS, on Android, and it doesn't seem to apply. –  Gdalya Mar 5 '12 at 19:06
what is the encryption that is being used then on your device? what device do you have? –  Ryan Conrad Mar 5 '12 at 19:07
I have a Droid Bionic. I'm not sure what encryption is being used. I assume that it's part of the Android Operating System. I'm using version 2.3.4. –  Gdalya Mar 5 '12 at 20:42
i have read that other motorola devices use encfs for the encryption, to that link may have applications that can help you. I dont recall that the encryption is part of the OS, well, the "vanilla os", I believe this is something that motorola added. –  Ryan Conrad Mar 5 '12 at 21:51

I sent this question into Verizon Wireless as well. Here is their reply:

Thank you for contacting Verizon Wireless through our website...I understand that you've been having an issue trying to decrypt files on your handset. At this time Motorola hasn't provided an update for your phone to be able to do this. Without that, we're unable to assist you because this is a phone issue and not a network issue.

So it looks like Ryan was correct in his comment that this is an issue with a Motorola OS add-on, not vanilla Android.

Since originally asking my question, I experimented some more with my phone. My phone has 2 check-boxes for setting encryption: one to encrypt the SD card (that I mentioned in my original question) and one to encrypt the main phone memory. When I unchecked both boxes, my phone decrypted all files, both on the phone and on the SD card. So, that is my solution for now.

Thank you Ryan for your comments -- they helped lead me to this answer.

I'm using Samsung Galaxy Note, ICS 4.0.3. There's a Decrypt option. Go to Settings - Security - Encryption, theres a "Decrypt Device" and "Decrypt SD Card" option.

After you select "Decrypt SD Card", just uncheck all the boxes on the next screen (see screenshot below).

Got a downvote for sharing my knowledge :( Anyway, I just decrpyted my Galaxy Note's SD Card a few minutes ago, because I can not access or edit my files stored on the SD Card (by attaching the USB cable and access as Mass Storage Device). After decrypting for around 25mins, I now have full access to my files. No files were damaged, back to normal. –  JonC PH Jun 13 '12 at 4:47

I encrypted a file and the whole day i needed to search on the internet for how to decrypt it but i found something that helped me,Icare data recovery and i recovered the encrypted file i didn't decrypted it and now i have it again but it still is encrypted somewhere on my phone so you can recover all the files with that program save them on the pc,format the sd card and you're done :)
