CrytoTool respects the people behind the screen. It's a four-in-one, client-side encryption file manager, gallery, music player, and document viewer where your privacy comes first on a simple, radical idea: no tracking, no ads, no data collection. Using a 100% client-side architecture and strong client-side encryption the database is protected with (AES-GCM & Argon2id) your sensitive data is protected and never leaves your device.
CrytoTool is compliant with the protocol and respects all the principles included in it: protocol-3305
Advanced Security & Privacy <<<<<<< HEAD
- IndexedDB Encryption: Files are automatically encrypted using AES-256-GCM with keys derived from your Master Password via Argon2id. For more details, see the Technical Architecture (Section 1).
- Strong Master Password: Secure your entire vault with a master password (minimum 30 characters).
- Encrypted Backups: Create fully encrypted backups protected by a unique, separate encryption key using PBKDF2-SHA256 and AES-256-GCM. For more details, see the Technical Architecture (Section 3). =======

- Critical Settings Password: Add an optional, second password to protect access to sensitive settings.
- Progressive Lockout: The app automatically locks for increasing durations after multiple failed password attempts.
- Self-Destruct Mechanism: Optionally configure the app to automatically and securely wipe all data after a set number of failed attempts.
- Access Recovery: Regain access to your vault if you lose your master password using either 10 single-use recovery codes or a unique, one-time reset token.
- Auto-Lock & Visual Obfuscation: The app can automatically lock and blur the screen after a period of inactivity.
Effortless Code Management
- Add Codes Easily: Add new 2FA accounts by entering details manually or by scanning a QR code from an image in your gallery.
- Powerful Search: Instantly find any code by searching for its issuer or account name.
- Safe Deletion: Move codes to a Trash area, from where you can restore them or delete them permanently. <<<<<<< HEAD
- Manual & Streaming Encryption: Encrypt files manually with 6 algorithms (AES-GCM, XChaCha20-Poly1305, ChaCha20-Poly1305, AES-CTR, Salsa20-Poly1305, AES-GCM-Stream). For more details, see the Technical Architecture (Sections 2 & 4).
Deep Customization
- Theme Gallery & Accent Colors: Personalize the app's appearance with a rich theme gallery and a custom accent color picker.
- Multi-Language Support: The interface is available in over 50 languages to provide a native experience for people worldwide. =======
