# Project - TODO:
|
|
|
|
[ ] implement SendMessage at the server
|
|
[ ] implement Login
|
|
[ ] client
|
|
[ ] server
|
|
[ ] Figure out how to do the messages themselves
|
|
[ ] implement sending messages properly
|
|
[ ] implement message acks
|
|
|
|
## Protocol todo:
|
|
|
|
[ ] Figure out how a message and message ack payload will look
|
|
[ ] Figure out server responses (hopefully manages to be stuck in a 512 bit block as well)
|
|
|
|
|
|
## Misc todo:
|
|
|
|
[ ] Create a Request to String function for easy printing and debugging
|
|
|
|
## client todo:
|
|
|
|
[ ] Check for key when turned on
|
|
[x] generate key and register if no key is preset, and save it after registration is done
|
|
[ ] if key is present, start by establishing connection (which makes sure we are signed in)
|
|
[ ] use AES to get basic packets from the server
|
|
[ ] use RSA private key to read normal messages
|
|
|
|
## Server todo:
|
|
|
|
[x] Laucnh task for each new connection
|
|
[x] use RSA key to get first message and extract AES key
|
|
[ ] verify the user using its public RSA key
|
|
[x] if it was a register session save the key into the BIG DATA STRUCTURE
|
|
[ ] Keep lists of incoming messages
|
|
(doesnt need to know from who, they are just big blobs of shlomp)
|
|
[ ] When user asks for incoming messages, make basic packet and append the incoming messages
|
|
- last byte is the "how many messages are left" byte
|
|
- each byte in the extra data will be the length of the next message, so
|
|
if there are 3 messages of length 128, 200, 300 bytes it will be
|
|
[128, 200, 300, 0 ...] and the actual position in the payload is easy
|
|
to calculate ([128, 200+128=328, 300+328=628, ...])
|
|
|
|
|
|
Register process:
|
|
|
|
Client Server
|
|
|
|
Send AES key (sk)
|
|
Send Register(pub key)
|
|
Get AES
|
|
Get Register
|
|
Send 6 digit code
|
|
Get 6 digit code
|
|
(1) Wait for user to input 6 digit code
|
|
Send 6 digit code (signed)
|
|
Get 6 digit code and verify (code, then sig)
|
|
Send OK/NACK
|
|
if NACK goto (1)
|
|
|
|
Login process:
|
|
|
|
Client Server
|
|
|
|
Send AES key (sk)
|
|
Send Login message (Phone, AES sig)
|
|
Get AES key
|
|
Verify AES sig with Phone-pub key
|
|
if sig is invalid: close connection
|
|
else: send stored messages because why not
|
|
|
|
Usual process get messages:
|
|
|
|
Client Server
|
|
|
|
Send GetMessages
|
|
Send back messages
|
|
Send GotMessages(amount) |
