Hash the transformed_key to get the final master keyįinal_master_key = sha256(transformed_key)

Transformed_key = concat(Master Seed, transformed_key) Transformed_key = sha256(transformed_key)Ĭoncatenate the Master Seed to the transformed_key Transformed_key = AES.encrypt(transformed_key, Transform Rounds) Use this cipher to encrypt the transformed_key Transform Rounds times Initialize the transformed_key value with the composite_key value kdbx files.Ĭreate an AES128-ECB cipher, taking Transform Seed as its seed

concatenate all hashed credentials in this order: passphrase, keyfile, WUA.

hash all credentials needed (passphrase, key of the keyfile, WUA).

concatenate all hashed credentials in this order: keyfile, passphrase.

hash all credentials needed (passphrase, content of the keyfile).

If you have just one credential, you are done after step 1. Generation depends on supported credentials ( see official info):

Generate the master key from the transformed key.

Generate the transformed key from the composite key.

Multiple keys must be generated to get the final master key.
