The composite key is invalid! Make sure the composite key is correct and try again

[sgreci]

Hello, i'm testing PoShKeePass with key files. I've created through the KeePass 2 windows interface a new database and configured the access only with a keyfile.

I created a KeePassDatabaseConfiguration:

New-KeePassDatabaseConfiguration -DatabasePath "C:\Projects\keepass\database1.kdbx" -DatabaseProfileName "profile1" -KeyPath "C:\Projects\keepass\database1.keyx"

and this is the result:

PS C:\Users\sgrec> Get-KeePassDatabaseConfiguration

DatabasePath       : C:\Projects\keepass\database1.kdbx
Default            : False
Name               : profile1
UseMasterKey       : False
KeyPath            : C:\Projects\keepass\database1.keyx
AuthenticationType : Key
UseNetworkAccount  : False

When i try to open the database and read an entry i got this error:

PS C:\Users\sgrec> Get-KeePassEntry -Title "localhost_user1" -DatabaseProfileName profile1
Exception calling "Open" with "3" argument(s): "The composite key is invalid!
Make sure the composite key is correct and try again."

Really don't understand what's going on because from KeePass 2 GUI I can open the database and read/write entries. Here below my versions:

Name                           Value

Same issue for me, but I'm not using a keyfile.

1.- If i pass the password manually it works 2.- If i used the System.Security.SecureString doesn't work and get the same error

I had similar issue. My initial keyfile, I've generated using Format version 2.0(recommended). However, when I've generated new keyfile using Format Version 1.0(compatible with older KeePass version/ports) I was able to use PoShKeePass with keyfile.
