Play with these numbers and increase them slowly, then use the Test button to get it as high as you can tolerate while still being relatively quick. Now it'll be version 4.1įor Argon2d, recommended starting parameters at 2 iterations, 1GB memory, 2 parallel.

Pick one of the groups on the left hand side, right click, edit group, go to Properties tab and add a random tag to the line there (I called mine 'test'). Go to File -> Database Settings -> Security and change Key Function to either Argon2d or Argon2id. I'm going to change to argon2, but I'd like to know which database version I was using after making the switch.įor anyone reading this in 2023, do the following to get the latest KDBX 4.1 database format: I don't know if by then KDBX 4 was enforced despite my encryption settings.įrom that same page, 'Up to KDBX 3.1, the number of rounds for AES-KDF was stored in the header field with ID 6 (TransformRounds)', but I don't know how and if you can check that somehow. These don't necessarily enforce the change as of KeePass 2.35 and I don't know if any of my plugins save any data to the database:Īlso, the post in the link mentions KeepPass 2.35 which was released in and I migrated to KeePass in august of 2019 with KeePass 2.42 which was released in. I'm using AES for encryption and AES-KDF. On this page you can see the conditions that force a migration to KDBX 4 (at least one must be met):ĪES-KDF is not selected as key derivation function (KDBX 3.1 only supports AES-KDF any other key derivation function, like for instance Argon2, requires KDBX 4).Ī plugin requests to store custom header data in the KDBX file.Ī plugin requests to store custom data in an entry or a group. I've been reading that KDBX 4 is better than KDBX 3.1 and I've been looking for ways to determine what's the version of my database.
