[support] Software license generation

[prothero]

Hi. I'm building a store (Drupal 6.20, ubercart.) and want to sell  
software licenses for students playing an online educational game. The  
current system (all in shockwave) uses md5 encoding with the salt  
including a course name and the registrant's email. So, each user or  
course that is registered gets a unique license.

I have considered two possible approaches:

1) Drupal itself generates the license, based on the user's email and  
the course title they enter.
or:
2) I send them to my other app to generate an ID code and they enter  
it when they purchase a license.

With approach 1, the advantage is better Drupal integration and a more  
streamlined user experience. There would have to be either a separate  
page where the user enters a course title and instructor email, or  
integration with ubercart in some way.

With approach 2, Ubercart still has to provide an entry field for the  
ID code and store it on the database, so my app can retrieve it and  
verify that the purchase has been made. I would verify the license  
from code within my game.

I am expert with the game code (Shockwave), but not with Drupal and  
PHP. So, option 2 might be easier to implement as long as I can add  
the field to ubercart. Then, as I become more familiar with Drupal  
coding, I can integrate it better.

Does anybody have any suggestions of modules that might help. The  
"Ubercart license keys" module seems to rely on pre-existing keys not  
ones generated from user input.

Thanks for any suggestions,
Bill
