very cool! i have been waiting for a compelling answer for running systems in isolated VMs on my machine and this is a very good approach! thank you for sharing!
The basic idea is [email protected] and [email protected] have public keys exposed, enabling Diffie-Hellman, enabling end-to-end encrypted communications for sharing secrets. This enables company-to-company secret sharing, e.g. environment variables, without requiring that both companies use the same common service provider for password management. The network architecture is modeled after email.
