6- Don't know where to start? Gradecoin uses RESTful API, simple `curl` commands or even your browser will work! [This website can help as well](https://curl.trillworks.com/).
7- [JWT Debugger](https://jwt.io) and the corresponding [RFC](https://tools.ietf.org/html/rfc7519)
8
9# Services
10## /register
11- Student creates their own 2048 bit RSA `keypair`
12- Downloads `Gradecoin`'s Public Key from [Moodle](https://odtuclass.metu.edu.tr/my/)
13- Encrypts their JSON wrapped `Public Key`, `Student ID` and one time `passwd` using Gradecoin's Public Key
14- Their public key is now in our database and can be used to sign their JWT's during requests
15
16## /transaction
17- You can offer a [Transaction](/transaction) - POST request
18 - The request should have `Authorization`
19 - The request header should be signed by the Public Key of the `by` field in the transaction
20- fetch the list of `Transaction`s - GET request
21
22## /block
23- offer a [`schema::Block`] - POST request
24 - The request should have `Authorization`
25 - The [`schema::Block::transaction_list`] of the block should be a subset of [`schema::Db::pending_transactions`]
26- fetch the last accepted [`schema::Block`] - GET request
27
28`Authorization`: The request header should have Bearer JWT.Token signed with Student Public Key

7POST request to /register endpoint
8Lets a [`User`] (=student) to authenticate themselves to the system
9This `request` can be rejected if the payload is malformed (=not authenticated properly) or if
10the [`AuthRequest.user_id`] of the `request` is not in the list of users that can hold a Gradecoin account
11
12# Authentication Process
13- Gradecoin's Public Key (`gradecoin_public_key`) is listed on moodle.
14- Gradecoin's Private Key (`gradecoin_private_key`) is loaded here
15
16- Student picks a short temporary key (`k_temp`)
17- Creates a JSON object (`auth_plaintext`) with their `metu_id` and `public key` in base64 (PEM) format (`S_PK`):
18{
19 student_id: "e12345",
20 passwd: "15 char secret"
21 public_key: "---BEGIN PUBLIC KEY..."
22}
23
24- Encrypts the serialized string of `auth_plaintext` with 128 bit block AES in CBC mode with Pkcs7 padding using the temporary key (`k_temp`), the result is `auth_ciphertext` TODO should this be base64'd?
25- The temporary key student has picked `k_temp` is encrypted using RSA with OAEP padding scheme
26using sha256 with `gradecoin_public_key` (TODO base64? same as above), giving us `key_ciphertext`
27- The payload JSON object (`auth_request`) can be JSON serialized now:
28{
29 c: "auth_ciphertext"
30 key: "key_ciphertext"
31}
32
33## Gradecoin Side
34
35- Upon receiving, we first RSA decrypt with OAEP padding scheme using SHA256 with `gradecoin_private_key` as the key and auth_request.key `key` as the ciphertext, receiving `temp_key` (this is the temporary key chosen by stu
36- With `temp_key`, we can AES 128 Cbc Pkcs7 decrypt the `auth_request.c`, giving us
37auth_plaintext
38- The `auth_plaintext` String can be deserialized to [`AuthRequest`]
39- We then verify the payload and calculate the User fingerprint
40- Finally, create the new [`User`] object, insert to users HashMap `<fingerprint, User>`
