Bulletinboard DHT and wireguard-p2p https://github.com/manuels FOSDEM 2018 February 2 nd

Mission Statement Connect any computers by just knowing their public keys 2

Bulletinboard: Kademlia Protocol 3

Bulletinboard: General Purpose DHT ● UDP-based, implemented in Rust ● DBus Service – Put Put(str str app_id app_id, , byte[] byte[] key key, , byte[] byte[] value value) – Get Get(str str app_id app_id, , byte[] byte[] key key) → byte[][] byte[][] values values – TODO: Subscribe(byte app_id, byte[] key) → byte[][] values ● Max. value size: Soft: MTU, Hard (2KB) 4

Wireguard VPN ● UDP-based ● Using Noise protocol ● Almost Linux mainline kernel $ wg genkey $ wg genkey 6KRW+XV/Ef6+zDtS6fO0Ype7qXcUzSs0lZDCVjWLyWg= 6KRW+XV/Ef6+zDtS6fO0Ype7qXcUzSs0lZDCVjWLyWg= $ wg genkey | wg pubkey $ wg genkey | wg pubkey +LrzGOqVx21DJ5yOmpgvXdTmnOm4EsH1Z3XtCnix9QU= +LrzGOqVx21DJ5yOmpgvXdTmnOm4EsH1Z3XtCnix9QU= 5
