Hi all,
I am hoping to sell a few noddy components I have created very cheaply. Can anyone suggest any ways of generating Registration Keys for the components?

I was thinking of getting the users to enter the Key and their names into some special properties in the component. Any other suggestions?

PS. They are not game related components. Actually one is a SourceSafe plugin for the Delphi IDE. The current ones on the market are way too expensive, so I created a cheaper alternative.
