Is there a good way to both create and verify a "license" code for use a FM app?
What I am looking for is to enable a feature based on a license key tied to a user or business name such that
1) the key can be generated by me and
2) the key can be validated by FM Pro given the token (business name or use name) and the type of license it is
EG: Username: Towncrest Pharmacy , License Type = feature1 Generated Key = AAAAAAAA-BBBBB-CCCC (or some such nonsense)
Then, with Filemaker Pro I could call a custom function that, given "Towncrest Pharmacy" and the above Key, returns a valid or invalid response
Any suggestions would be most welcome.
