Decryption fails running iOS 14.2
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?
I also have success opening an encrypted file within Dropbox after updated 14.4 IOS update. Thanks for everyone's help and input.

Hi JohnK2, thanks for posting!
Could you send me a screenshot of the error that you're getting?
Also, what are the exact steps you're taking when you get this error?
When you mentioned opening the file through Excel, was this by opening the file through the Files app, or after exporting the file from Dropbox?
Keep me posted!
Also, on my iPhone, I open dropbox and go to that combo file. Enter my password and get the result above. If i click on the "open" button, then I am able to open in Excel with my password. Never had to do this before my iOS upgrade yesterday. My wife's phone has the exact same issue. We are able to open on our macs but not our iPads or iPhones.
- Me too. Just installed 14.2 but it happens when opening excel file from email so not just dropbox
- Same here with a word document. Strange though, as I have 2 encrypted docs on Dropbox... one opens, the other doesn’t.
I am having exactly the same problem. I upgraded my iPhone and iPad to iOS 14.2 yesterday. Today I cannot open password-protected Word files on DropBox on either device. I get the same message as was posted earlier. I can open up files without a password but not any with a password. I hope there can be a fix or workaround for this.
same problem, I don't yet see a fix in the replies?
- Same problem here! Cannot open MsOffice files protected with password, same error message DECRYPTION FAILED (NULL) after installing ios14.2...Please fix it. Thank you!
What is the fix???
- Actually nothing but downloading the Excel app on the phone and use it to open the protected document in dropbox. Until dropbox fix it as it was before ios14.2, of course
- Me too
- Same issue since I updated my iPhone!
- Thanks for posting this about 14.2. I’m running 14.2 on iPhone 8 with no issue when I use the password to open my secured document, but my wife can’t do it on her iPad running 14.2. Seems inconsistent based on other comments that it’s on one or both. I’ve had iOS 14 for about a week with no issues on this topic, and I just downloaded 14.2 on iPad for my wife yesterday, and then it quit working. I have Excel and it also opens the document with no issue, however she does not have it installed, so not sure if there’s a correlation or not. Any updates from Dropbox on this issue will be appreciated and sooner rather than later please. Thanks!
- I am having the same problem on IPhone 11 running IOS 14.2.
I'm experiencing the same problem. I found that going back to the original Word document, and resaving it as a .doc file (not .docx) is a workaround.
When you do this, you may get a warning that .doc file encryption isn't as strong as .docx encyption; I think that could be a clue to what is happening, and the problem is that ios14.2 has a problem with the stronger encyption. But falling back to .doc is a temporary workaround until Apple fixes the problem.
Did we ever get a solution to this or do I have to give up on Dropbox?
You won't get a solution until Apple releases a fix. All we have are work arounds as posted in this thread.
same for me today on my Ipad and Iphone.... grrr
- I can’t open my file because “Decryption Failed.”
Why? Yep, upgraded to iOS 14.2 and I'm getting the "encryption failed (null)" error too, when trying to open a password-protected MS Word doc in my Dropbox app.
I have the same problem
I did find a temporary work around. If you have MS Word installed as an app on your devices, you can open the document that is password-protected through Word via DropBox. This allows your to enter the password. I am not sure if it is the same if the issue affects Excel. I still am hoping for an update with a fix from either Apple or DropBox. Do the DropBox admins ever comment on these threads or is it just users?
Yes, same with Excel. Hopefully Daphne from Dropbox will get back to me with an answer today.
- Same issue trying to open excel files won’t iOS 14.2,from mobile outlook. File dirs open directly from excel. This seems to be an iOS 14.2 issue. Apple needs to take note ASAP.
Yes. I just had the identical error message appear.
Same problem here on my Ipad and iphone
All Excel files with password protection give a decryption error when tryong to open them after giving the correct password.
I Saw this also happens With SYNC (another cloud service)
So it is a Apple IOS 14.2 problem.
