Unique links for digital products

Hey,

I’m looking for a solution to have unique links with a random string in URL to download digital products in my store, which are generated automatically after every purchase for a customer, and they replace original URL to digital File.

For example now in a product settings, in General settings in “Files to download” links have this structure: http://down.mysite.com/t7TSszCO. And I would like to have this random string at the end unique for each client. So it will be some auto url shortener ..

Does anyone know some addon or other solution to achieve something like that? Apart from custom coding of course ..

BR,
