Apricorn's fourth generation of Secure Keys offers next-generation security features and up to 25% cooler operating temperatures. The 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 ensure maximum security. All data is encrypted during operation, and the PINs and device data remain encrypted while the drive is at rest. The product is fully cross-platform and operating system independent; it works with Windows, Linux, Mac, Android, Chrome, embedded systems, and devices that have a USB power supply and a storage file system. All internal components are protected by a layer of hardened epoxy resin against physical tampering, and the locked firmware makes the device immune to malware attacks such as BadUSB.
