CryptoKey is a secure USB flash drive that combines hardware-based data encryption with multi-factor authentication capabilities. **Encryption:** The device uses AES 256-bit encryption in CBC mode, applied automatically and in real time by an on-board hardware controller. The data encryption key is generated on the device during setup and never leaves the drive. The drive is protected by a user-set password that is not stored on the device in any form, making it resistant to compromise. **Brute-Force Protection:** A hardware-based unlock attempt counter is built into the device. After a configurable number of failed unlock attempts, the drive is permanently locked down, preventing brute-force attacks. **Antivirus / Antimalware:** The device integrates the BitDefender antivirus and antimalware engine directly into its firmware. All data written to the drive is scanned in real time, preventing the drive from being used as a vector to spread malicious software. **Multi-Factor Authentication:** CryptoKey includes two built-in authentication tokens: an OTP (One Time Password) token for strong authentication, and a PKI smart token for certificate-based authentication. The device is designed to function as both a secure encrypted storage medium and a hardware authentication device, combining data protection and identity verification in a single USB form factor.
