The algorithm uses the PID of the application for the serial key calculation. It also uses the ‘GetComputerName’ and ‘GetUserName’ win32 APIs in generating the serial key. The length of both results are used for the loops and each ascii value is added. These results are used in the final calculation in the serial key.
This graph is from the OllyGraph plugin.
