Insufficient memory to proceed when opening Argon2 database #261

Closed OculiViridi closed 2 years ago

OculiViridi commented 2 years ago

Description

When selecting suggested entry from iOS autofill on a website form, instead of autofilling the field, KeePassium opened the app, asked which database to select and once selected the correct database, the following error appears (copied from app's log file):

Additional information

The database is KeePass v4 format using ChaCha20 encryption and a key file v2 (.keyx file). The key transformation settings are:

The average opening time on PC is less than 0,5 seconds. The database is stored on OneDrive.

How to reproduce

Steps to reproduce the behavior:

  1. Open a webform and on a user/password field
  2. Tap on the auto suggested value taken from KeePassium.
