Converting Amibroker AFL to DLL

I want utility to convert AFL code of Amibroker to DLL plugin to hide original formula, and also to protect the DLL and making it hardware locked. I want to wrap the DLL with security, or license ,then it will have expiry date, this expiry date then can be set to 30 days, 90 days,etc. The result should be an executable file. When it run, can automatically install the DLL plugin to Amibroker [login to view URL] default expiry date of the DLL can be set (e.g 05 days) , and can be extended through entering a long code in relation to the machine serial number.
