Implementing a security key
|

Has anyone implemented a security key to allow an application to function for a desired time frame? In other words, if you wanted to create annual activation keys. I was considering a .CC since it cannot be decompiled and changed. What I need to figure
out is how to keep a hijacked copy from also ussing a hijacked copy of an activation key.
Is there a way to get a unique number from any particular PC that can be compared to a variable in an activation key?
Thanks,
JM

| This vbscript will grab it & send it a text file. I know dBase can
access WSH scripting objects thru OLE, but not sure how to call that
first getobject() function, since it doesn't belong to a specific WSH
object. Good luck.
'This VBScript will grab each CPU Serial # and stuff it into a textfile.
Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_Processor")
Set fso = CreateObject("Scripting.fileSystemObject")
Set LogObj = fso.CreateTextFile("CPUID.txt",true)
For Each objItem in colItems
LogObj.WriteLine(objItem.ProcessorId)
Next
LogObj.Close
Cheers,
Christian K.

What about using a .CC that includes a predefined date, then compiled and sent to the user? Has anyone developed such a solution and be willing to share the implementation?
