Security:
Uses AES-256-GCM. The key is extracted from the password with PBKDF2-HMAC-SHA256 (120,000 iterations, random salt).
Files are encrypted in authenticated 64 KB blocks. Therefore, the memory remains persistent, and any change, block swapping, or truncation of the file is detected.
If the password is incorrect, the partially saved file is automatically deleted.
Other things in the project:
Language in the application, regardless of the phone language: English (default), Bulgarian, Deutsch, Français, Español.
