CrytoTool respects the people behind the screen. It's a four-in-one file manager, gallery, music player, and document viewer built on a simple, radical idea: no tracking, no ads, no data collection. Using a 100% client-side architecture and strong, modern end-to-end encryption, your data is always protected.
The application and backups are secured with AES-GCM, derived from your master password. For individual file encryption, you have the flexibility to choose from a suite of elite algorithms:
- AES-GCM & AES-CTR
- XChaCha20-Poly1305
- ChaCha20-Poly1305
- Salsa20-Poly1305
Your files are protected and never leave your device.
CrytoTool is compliant with the protocol and respects all the principles included in it: protocol-3305
Advanced Security & Privacy
- Robust Master Password: Enforces a strong, 30-character minimum master password to secure the entire application.
- Two-Factor Authentication (2FA): Add an extra layer of security to your login using any standard TOTP authenticator app.
- Brute-Force Protection: The login screen features progressive lockout, while the optional Self-Destruct mechanism can be configured to wipe all app data after a set number of incorrect password attempts.
- Critical Settings Password: An optional, secondary password to protect the Settings page from unauthorized changes.
- Secure Data Shredder: When enabled, permanently overwrites data on deletion to make it unrecoverable.
- Encryption Key Vault: Securely save and manage your file encryption keys in a separate, PIN-protected vault, featuring progressive lockout and a blacklist of common, weak PINs.
- Elite Encryption Suite: Encrypt individual files with your choice of modern algorithms: AES-GCM, AES-CTR, XChaCha20-Poly1305, ChaCha20-Poly1305, and Salsa20-Poly1305.
- Timed One-Time Keys: Generate temporary, time-limited keys to grant secure, short-term decryption access to a specific file.
