Re: "Lagrange is *seriously* impressive. Once I can sync…"

In: u/sam

@skyjake we're thinking along the same lines here.

Each user has:

• Master key (MK) used to encrypt/decrypt bookmark data.
• Public/Private Key Pair (PK, SK) for device authentication & key exchange.

Data is encrypted using AES-GCM or XChaCha20-Poly1305 for better nonce security.

When a new device is added, the existing device shares the Master Key encrypted with the recipient device’s public key.

All the server needs is a way to associate different public keys from different devices with one set of data. It would be nice to avoid usernames but that's one simple solution.

Lagrange is *seriously* impressive. Once I can sync bookmarks and certs easily between clients it'll be near perfect.
