A small Drupal 10 admin module that generates large numbers of unique, non-sequential coupon codes using a prime-based obfuscation algorithm

It provides an admin settings form and a generator form with an option to either output generated codes on the page or export them as a CSV download.

The obfuscation algorithm is based on this blog post & the wotzebra/unique-codes package.

Features

Generate large amounts of unique coupon codes in a single operation.
Choose output: show codes on the page or download a CSV file.
