Can not open database with both KeyFile and MasterKey - The composite key is invalid

[xanthar]

Hi.

I create the profile:

New-KeePassDatabaseConfiguration -DatabaseProfileName default -DatabasePath "<VALIDPATHTO.KDBX>" -KeyPath "<ValidPathTo.keyx>" -UseMasterKey

I then try to get entries:

Get-KeePassEntry -DatabaseProfileName default |select *
KeePass Password: **********

I get the following error:

Exception calling "Open" with "3" argument(s): "The composite key is invalid!
Make sure the composite key is correct and try again."
At C:\Program Files\WindowsPowerShell\Modules\poshkeepass\2.1.3.0\PoShKeePass.psm1:2664 char:9

  • FullyQualifiedErrorId : InvalidDatabaseConnectionException : The database is not open.

I have tried without the -MasterKey switch.
Also i am sure the paths to the files are correct and the password (Masterkey) entered is correct (Have checked, double and trippel checked in KeePass directly).

The only way i can get this to work is to remove the KeyFile completely from the database. But i would like this option for extra security measures since the database is used by administrator team.

What am i doing wrong here? As mentioned the KeyFile(.keyx), the .kdbx file and the masterkey has been verified directly with KeePass.

I read this issue:#191
and temporarily fixed it by also changing the KeyFile to version 1.
But it would be great if this could be updated to work with V.2 keyfiles.

You have to set Paramater -UseMasterKey in the command for create the Profile
The Documentation is not correct for Profile with MasterKey.
New-KeePassDatabaseConfiguration -DatabaseProfileName 'KeyFileDB' -DatabasePath "Database.kdbx" -KeyPath "Database.keyx" -UseMasterKey

For Read use: ($psw = ps secure string)
use:Get-KeePassEntry -KeePassEntryGroupPath 'Database/default' -AsPlainText -DatabaseProfileName KeyFileDB -MasterKey $psw
This only works with key Version 1.
