Hi Acme,
using the sample key and sending it to alice@gpg4win.de should work for me.
All components in Gpg4win are “Free Software” (from the meaning of “liberty”) and you
can use the common version without mandatory fee.
For the precise legal terms, see https://www.gpg4win.de/license.html
- We ask people to pay something volunteeringly, so we can keep this service and the maintenace up.
- There are additional paid-for services, e.g. when you need Gpg4win for many work places and high or very high security setting, we recommend you check into the “GnuPPg VS-Desktop”, to ensure operating support, see https://gnupg.com/index.html
Again, summarized: Yes, you are allowed to use Gpg4win without fee for business use.
Best Regards,
Bernhard
