PassphraseBasedKeyManager class abstract
An extension of the standard KeyManager that generates it's master key based of a passphrase.
This class implements loadRemoteMasterKey by deriving the key from a passphrase as well as other parameters. Those parameters must be provided by implementing the loadMasterKeyComponents method.
Note: The used generation algorithm is very computation heavy and thus might freeze the UI for a few seconds. This is by design, to ensure keys cannot easily be brute-forced by just guessing passwords. To prevent the ui from freezing, you should use the ParallelMasterKeyComputation mixin to run the code on a separate isolate.
