Hi! I'm one of the Charm co-founders.

We actually issue a new Charm specific SSH key for you. We then allow you to link machines together with our `charm` account utility. The symmetric keys used to encrypt data are encrypted for each public key linked to your account so you can access your data from multiple machines.

Thanks for the explanation! Glad to hear you've thought out and handled the linking process.

Just out of curiosity: have you seen or considered age[1] for the symmetric pair? I've used it on a few projects where cryptographic flexibility wasn't necessary.

We actually ended up making our own encryption library that's based on age, it's called sasquatch (built by our team member muesli):
