I might be interested in ordering a laptop with anti-interdiction services. Apparently this would involve coordinating shipping details with Purism as well as receiving pics of glitter-sealed screws via encrypted email. What is recommended on my end to communicate securely with Purism?
I currently use Protonmail but I don’t have any experience sending and receiving email using PGP or GPG (aside from the built-in PGP when sending between two Protonmail accounts). Is it possible to use my existing Protonmail account to communicate securely with Purism (assuming that Protonmail is trustworthy)? Or should I take this opportunity to set up a more secure mail account to coordinate shipping?
I should also mention that I will be communicating via a mobile device running Graphene OS, so ideally, any additional services would be fairly straightforward to setup.
