Licensing for your Go app.
Generate certficates and use those certificates to sign licenses.
The idea here is not to make this removal- or crack-proof. It's pretty widely accepted that DRM does not work and can easily be subverted or removed.
This library is useful if you want to add some usage-based licensing to your app.
DO NOT expect this to be a bulletproof licensing system that prevents all malicious actors.
It is not, and will never be, designed to do that.
