i would see this as more of a potential use as something for activating a product, sort of like you get a code from the producer, put in this and it gives you the code to get the code for activation, unfortunately as Ether said you would have to do a lot more work to make it a actual "keygen".

I think you mean that you made a die simulation program that will display some text rather than a number.
Sorry, but this isn't a keygen, it's just displaying some codes you will obtain from other actual keygens released by the crack groups.

To improve it you need to figure out and include the mathemetic formulas used to generate and verify actual unique keys to call it a keygen.

Obviously, that's rather hard to do without reverse engineering the copy protection systems for the specific application.
