I've created a new Craft CMS project and installed Nitro to run everything in a VM. Now I'm wondering if it's possible to use SSL for the local domain? I didn't found anything in the documentation.
Checkout Nitro 2, it now has full SSL support
SSL isn't currently available in Nitro–though it is on the roadmap for development. See github.com/craftcms/nitro/issues/10.
