As an engaged user you could also contract for some specific step, update, bug fix or new features. Take care that your contracted improvements will be integrated into the main development of Gpg4win.

As a company or authority contract for more extensive measures that will ensure continuation of the project. This way you will ensure sustainable availability of Gpg4win for your organization. Such measures do provide the collateral benefit of generally improving security for data exchange.
