KeepassDX/KeepassXC Database incompatibility

[cubicconsult]

Overview

I am unable to use my KeepassXC database in my KeepassDX mobile app as claimed in the KeepassXC FAQ

Steps to Reproduce

1. Create a new database in either KeepassDX or KeepassXC
2. Copy to the other device
3. Try opening the database with the "compatible" app

Expected Behavior

KeepassDX should open a KeepassXC database and vice versa

Actual Behavior

KeepassDX is unable to open a KeepassXC Database and vice versa

Context

KeepassXC FAQ explains there is no need for a mobile version because it is database compatible with The KeepassDX

KeePassXC - 2.6.6

Operating System: Windows/Andriod

What error do you receive?

What error do you receive?

KeepassDX: Could not read credentials.
KeepassXC: Invalid credentials provided.

I use KeePassDX every day, can assure you that it works with KeePassXC. Did you create the database in DX or XC?

I tried both ways...

[droidmonkey]

You are probably using the wrong password or if you use a key file it is corrupt.

@cubicconsult Why you are using KeePassXC 2.6.6 instead of the latest 2.7.0 release? Try to update it.

[cubicconsult]

I started having this issue before 2.7.0 was release JUST ABOUT WEEK NOW on March 22. I have downloaded 2.7.0 though. However will it update the database structure?

[cubicconsult]

You are probably using the wrong password or if you use a key file it is corrupt.

Wrong password? No. I used the same password for both databases. And I copied the files back to ensure they were not corrupt AND USED THE SAME PASSWORD and it opened in KeepassXC. So definitely not a password issue...

[droidmonkey]

You need to be more clear on what the problem is because what you just said conflicts with what you said earlier.

[Nickoriginal]

However will it update the database structure?

Sure. See at least #7114 (new database format KDBX 4.1 implementation). Also many other change related to the base management and app usability.
Please, always check for updates and update to the latest versions of the apps before reporting issues.

Lol. No conflict please. Let me break it down:

1. I copied my KeepassXC database to my mobile
2. KeepassDX could not open it
3. To check if the database was somehow corrupted in my mobile, I copied it back to my device and it opened in KeepassXC

So it is not a password issue because I am using the same password on both devices. Hope clear?

I'll confirm if that fixes it. Thanks!

NB:
However note that I have been having this issue and searching online BEFORE 2.7.0 was release on March 22nd...

Well, I'm glad to see your problem solved! If you encounter the same problem later, you can also report it.

Sorry I did not say it is solved, but that I will update to version 2.7.0 and get back. I have done that and the database was not updated by 2.7.0. What do I need to do for the database to be updated? I have opened and closed it with v2.7.0 but it was not modified...

[cubicconsult]

Sorry, mistakenly closed. Still getting to understand this interface. Lol.

[Nickoriginal]

Wait, it doesn't work so. App can not update databases to equal with self versions, it can only update it to more fresh database format, compatible with all ports.
New database formats include more features, like tags, groups and other.
For example KeePassDX app has introduced KDBX 4.1 format support in version 2.10.0 in May 2021, but KeePassXC did this right now in the version 2.7.0. If you will create the database in the fresh KeePassDX app version that requires KDBX 4.1 support and then open it in the KeePassXC 2.6.6 and older, you might encounter various errors when trying to open it in KeePassXC, that's why I asked you to update the app. Not important what version of your database are, because all KeePass ports are compatible with them.

[Nickoriginal]

Your database will be updated to more fresh database format automatically, when you will use its new features, like mentioned here so there is no need for you to update it manually.

[Nickoriginal]

Sorry, I saw "I", but not "I'll"

[Nickoriginal]

In this case can you try other KeePass apps like these both for Android, and this one for Windows? (for example create in KeePassXC and open in KeePassDroid to ensure that your database is not corrupted)

[cubicconsult]

I have included the error from both apps

Ok. So I can, say, add a tag and that's it right?

I'll check them out and get back. Thanks!

NB:
As indicated above when I copied the database back from my mobile to my pc it was opened showing it is not corrupt. Unless it is a corruption that KeepassXC accepts! Lol

[Nickoriginal]

Yes, but not limited by. In KDBX 4.1 compatible app and database you can also assign them into groups and much more.
Just use fresh versions of the apps.

[Nickoriginal]

@cubicconsult you can now unlock your database on other devices at least using other KeePass ports?

[Nickoriginal]

Strange case. Should be closed if author does not respond.

[droidmonkey]

Yes there is nothing we can do here, I use DX and XC together every day.
