Just updated iPhone and iPad to iOS 14.2. Now, trying to open an encrypted file, it tell me "Decryption Failed. Null" If I open with Excel, it works fine. Anyone else having this issue?
This may have been mentioned as a work-around already. When you bring up a Word document that is password protected, instead of trying to open it within Dropbox from the first screen that appears with the request for a password, click on "OPEN" which will cause the document to open in MS Word. The password requirement will be shown in Word and it will successfully accept the password. This also works for me with Excel documents.
Yes, same issue for our entire team using Dropbox for Business. We found a related thread on Microsoft's community site, so definitely not the only ones experiencing this issue. Now, whether or not it will ever be addressed is another thing, because we could see every involved party (Apple - iOS, Microsoft, and Dropbox) all potentially pointing the finger at the other company, saying, "It's their fault."
Thank you for looking into this as I have wasted a lot of time and concern on this decryption failed. (null) message.
My ticket is #11698965

Hi all,
I did a little investigating and here is my UX.
First of all, until recently, my process was like this:
1) I'd open the Boxcryptor app on my iPhone
2) I'd launch a Boxcryptor-encyrpted Excel file (which also happens to have password-to-open protection)
3) Excel would ask me for a password, and I'd enter it
4) My file would open (in read-only) and I could navigate around.
After the iOS update, the above process fails because, as everyone has indicated, the app renders a "Decryption failed. (null)" error in Step 4 (after I enter the password).
As a workaround, and perhaps it's a better process anyway, I don't launch the Boxcryptor app at all now. As long as it's installed, I just launch the Excel app.
But of course like on my computer I find my encrypted app in the Boxcryptor folder not directly in the Dropbox folder. (If you see ".bc" in the file name you can't open it unless you go through the Boxcryptor folder. This of course is by design.)
Within the Excel app, once I find my encrypted file in the Boxcryptor folder and launch it, it asks me for my password and then it opens up no problem. And it's actually better this way, because I can edit the file with the Excel app, and it has much stronger navigation features. (I'm not sure if I was always able to do that in the past, but I haven't checked in years. This issue has forced me to change to a better habit.)
So for MY experience, I just need to stop launching the Boxcryptor app - just leave it installed on my iPhone. To open my MS Office files I will use an MS Office app instead, and go in through the Boxcryptor folder. All is well.

Thanks for the explanation. have you checked it also with password protected Excel files in Dropbox?
Spinetta, I would highly suggest reading the whole thread. May take you maybe 10 minutes. And yes, your answer is there.
With the new Iphone 12, the Excel type file (.xlsx) with access code is no longer available when you type the access code.
