Guardant dongle is a highly effective mean of software/hardware protection. It allows building protection of virtually any level of complexity and tamperproofness.
Native-application (Win32)
Use automatic protection utilities for protecting ready-to-use applications against the attempts to learn their operating logic. To ensure proper protection it is recommended to use the following options:
...
In the event when the tie is done to Sign or Time dongle use ECC160 asymmetric algorithm operating option. Whereas, random data will be generated and signed by a digital signature on elliptic curves directly in the dongle in the course of operating the protected application. Later the signature will be verified by Guardant API function, protected by pseudo code, traffic encryption and other protection mechanisms.

.NET applications (Framework 2.0 – 4.0)
Use the symbol obfuscator and MSIL-code protection utility. It is also reasonable to use the following options:
...
