Guardant-Sign加密狗介紹：

●A dongle for software licensing, protection, and distribution with Windows and Linux support. Built on a high-performance 32-bit Cortex-M3 ARM microcontroller architecture. The dongle contains hardware-implemented digital signature algorithms based on elliptic curve cryptosystems and AES encryption.

●Built-in 4KB of protected memory expand the possibilities for building flexible protection schemes. High resistance to hacking is achieved through a secure communication protocol between the application and the dongle. Secure remote memory update of the dongle is supported. Allows you to work without any additional drivers.
