Introduce

This project is consist of a dll which used by CANoe/VSpy3/ETS to generate security access key automatically and a set of demo programs that use the dll to generate special keys.

• algorithm: The Dll used by CANoe/VSpy3/ETS.
• eol: A console program to generate EOL mode key.
• programe: A console program to generate programming mode key.
• extend: A console program to generate extended mode key.
