Developer: Linh Do Huu
Genres: Productivity, Utilities

Powered by ChaCha20-Poly1305 (https://developer.apple.com/documentation/cryptokit/chachapoly), encryption chosen by Google, 1LimX app version 2 changes:

  1. Faster encryption (see app video preview).
  2. Mass information fill from camera capture or library image to item form fields now supports datetime value (see app video preview).
  3. Free tier up to 125MB per file attachment.
  4. Autofill website login inputs now supports 2FA code (see app video preview).
  5. New dark mode theme.
  6. Now in Settings -> See master key, you can authorize to see the master key in QR code image. If you have new devices to install 1LimX, just scan that QR code to get the master key.
  7. Import password from Chrome browser CSV, XLS, XLSX,.. or any file with the same format.
  8. New custom data encryption tool for text and files:

       The current way if you want to encrypt and decrypt a file or text: create an item(such as internet account item) → create new text or file field with data selected → press Save, it'll be encrypted → create a backup of that item to get the final encrypted file to use on other devices with 1LimX installed.

       Now with the custom data encryption tool, text can be encrypted and decrypted right on the screen. With files, just select the file to be encrypted or decrypted and select a folder to save that encrypted or decrypted file.

    For multiples files encryption at once, you still need to use the current way.
