This tool uses client-side encryption. Your password and message never leave your device.
Security depends on a strong, unique password. Weak passwords can be cracked.
Email is not end-to-end encrypted. Use secure channels for sensitive data.
Not suitable for high-security needs (e.g., government or financial data). Use professional tools like PGP or VeraCrypt.
Always verify the source of encrypted messages to avoid tampering.
Browser-based: Ensure your browser is secure and updated.
