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.

        WOW that wasn't a very helpful answer since there are hundreds of posts and not many direct answers. I found a work around but not an answer to fix the problem.

    Install Excel on your iPhone and you can open password protected/encrypted files with no problem.

      I loaded Excel onto my iPad Air and it still comes up with the Decryption Fail error message. This has to be a Dropbox issue as too many people are experiencing the same proble.

        Please read all the posts. This is NOT a drop box issue. You should be able to open the document with excel or office for iOS. It is occurring with many apps including Microsoft one drive. Apple has changed they way the handle password protected office docs. I beg you to take the time to read the full thread.

      Everyone is talking about Excel but I don't have ANY saved Excel files in Dropbox, only WORD files.

      The problem only appears on my phone iPhone 11, NOT my computer. Dropbox.

      I have not found a useful thread about this issue yet and do not understand some of the remarks people are saying, they are obviously more computer techno savvy than me.

      Some people talk about resaving WORD files but how do I do that on my phone if I can't open the file? Do I go into my computer Dropbox and resave all the WORD files in Dropbox to something else. Most are saved as .docx, what I should I try and resave them as?

      Do I do this on my computer Dropbox?

      Like I say, most of the remarks are not helpful for me.

        Select the Word file you want to open. A screen will appear with a field for that document’s password. Leave the password field blank and select, at the bottom of that screen, the icon that is a small square with a line from its center to its upper right corner. A new screen will appear with a password field. Enter your password in that field and your Word document will open.

    Good Afternoon community,

    Please can anyone tell me if DB has fixed this problem in collaboration with Apple / MS yet? It still appears to be impossible to add a password to an MS Word Document then get it to open on the phone app. Mac OS seems to be just fine as previously stated by original  poster (John).

    Since 2 weeks I am no longer able to open excel files (most of them on dropbox from years) protected with password from the mobile app.

    Dropbox prompt me the "insert password form", but when type it the result is "decryption failed (null)". The same files are easily accessible and readable both on pcs and macs, with the same password...

    How can I solve this matter?

    Thank you so much

      PLEASE READ most recent message thread. On Apple devices (phone & iPad) this is resolved by updating these devices to IOS 14.4

    On my IPad. If I try to open a Word document from Dropbox it won't open. Says in won't decrypt. If I go through the Word icon and then search through to the document of Dropbox it will open. The document has a password but using this makes no difference. This did not used to happen. How do I get around this problem. Please.

      I hope you're well today Everitt!

      We had some similar reports, and many noted that updating to the latest iOS version resolved this for them here.

      Can you check if you have any pending OS updates to see if that does the trick?
