KeePassSubsetExport

KeePassSubsetExport is a KeePass2 plugin which automatically exports a subset of entries (tag based) to new databases with different keys.

Why?

I'm using the plugin to export some entries of my main database to another database which is synced to my mobile devices. Additionally, I'm sharing some other entries with my family.

Disclaimer

This is my first KeePass plugin and I tried not to compromise security - but I can't guarantee it.
So use this plugin at your own risk.
If you have more experience with KeePass plugins, I would be very grateful if you have a look on the code.

How to install?

Download the latest release from here
Place KeePassSubsetExport.plgx in the KeePass program directory
Start KeePass and the plugin is automatically loaded (check the Plugin menu)

How to use?

Open the database containing the entries that should be exported
Create a folder SubsetExportSettings under the root folder
For each export job (target database) create a new entry:

Setting	Description	Optional	Example
`Title`	Name of the job	No	`SubsetExport_MobilePhone`
`Password`	The password for the target database	Yes, if `SubsetExport_KeyFilePath` is set	`SecurePW!`
`Expires`	If the entry is expired the job is disabled and won't be executed	`-`	`-`
`SubsetExport_KeyFilePath` [string field]	Path to a key file	Yes, if `Password` is set	`C:\keys\mobile.key`
`SubsetExport_TargetFilePath` [string field]	Path to the target database. (Absolute, or relative to source database parent folder.) (`,` to delimit multiple target dbs)	No	`C:\sync\mobile.kdbx` or `mobile.kdbx` or `..\mobile.kdbx`
`SubsetExport_Tag` [string field]	Tag(s) for filtering (`,` to delimit multiple tags - `,` is not allowed in tag names)	Yes, if `SubsetExport_Group` is set	`MobileSync`
`SubsetExport_Group` [string field]	Group(s) for filtering (`,` to delimit multiple groups - `,` is not allowed in group names)	Yes, if `SubsetExport_Tag` is set	`MobileGroup`
`SubsetExport_KeyTransformationRounds` [string field]	Overwrite the number of KeyTransformationRounds for AesKdf	Yes	`10000000`
`SubsetExport_RootGroupName` [string field]	Overwrite the name of the root group in the target database	Yes	`NewRootGroupName`
`SubsetExport_FlatExport` [string field]	If `True` no groups will be created in the target database (flat export)	Yes (defaults to `False`)	`True`
`SubsetExport_OverrideTargetDatabase` [string field]	If `True` the traget database will be overriden, otherwise the enries will added to the target database	Yes (defaults to `True`)	`True`
`SubsetExport_OverrideEntryOnlyNewer` [string field]	If `True` only newer entries will overrides older entries (`OverrideTargetDatabase` is `False`)	Yes (defaults to `False`)	`True`
`SubsetExport_OverrideEntireGroup` [string field]	If `True` will override entire group in target Database (`OverrideTargetDatabase` is `False`)	Yes (defaults to `False`)	`True`
`SubsetExport_Argon2ParamIterations` [string field]	Overwrite the number of iterations of Argon2Kdf	Yes	`2`
`SubsetExport_Argon2ParamMemory` [string field]	Overwrite the memory parameter of Argon2Kdf	Yes	`1048576` = 1MB
`SubsetExport_Argon2ParamParallelism` [string field]	Overwrite the parallelism parameter of Argon2Kdf Typical parallelism values should be less or equal than to two times the number of available processor cores (less if increasing does not result in a performance increase)	Yes	`2`
`SubsetExport_ExportUserAndPassOnly` [string field]	If `True` only the username and password will be exported to the target database.	Yes (defaults to `False`)	`True`

Every time the (source) database is saved the target databases will be recreated automatically
To disable an export job temporarily just move its entry to another folder
If both SubsetExport_Tag and SubsetExport_Group are set, only entries matching both will be exported
