The fourth generation of Secure Keys from Apricorn offers next-generation security features and up to 25% cooler operating temperatures. It features software-free, 100% hardware-based 256-bit AES-XTS encryption, onboard keyboard PIN authentication, and ultra-fast USB 3.1 (3.0) data transfer speeds. All data is encrypted during operation, and the PINs as well as the device's data remain encrypted while the drive is at rest. It is fully cross-platform and operating system independent, functioning on Windows, Linux, Mac, Android, Chrome, embedded systems, and devices that have a USB power connection and a storage file system. All internal components are protected from physical tampering with a layer of hardened epoxy resin, and the locked firmware makes the device immune to malware attacks such as BadUSB.
