# Todo

## peer discovery

- get rsquest to the uri /peers/

## registration with the server

- generation of the cryptographic key OK
- put request to the uri (check if the peer is already connected) OK
- udp handshakes OK
- get request to the uri /peers/key to get the public key of a peer OK
- get request to the uri /peers/key/addresses OK

## handshake

- handshake structure OK

- 5min timeout after handshake
- matain connection every 4 min

## data transfer

- request structure
- root/root reply structure
- datum/nodatum and datum structures
- nattraversal 1 and 2 structures
- setting in gui to act as a relay
- chunk, directory, big, bigdirectory structures

## fonctionnalités application

## nat traversal

- make hello and helloreply messages set the first extension bit to announce that peer is available for nat traversal
- implement actual nat traversal requests
- implement nat traversal :
  - if hello/helloreply doesnt work with a peer, find a peer that supports nat traversal (server in priority) then begin protocol
