 POST request to /register endpoint
-Lets a [`User`] (=student) to authenticate themselves to the system
-This `request` can be rejected if the payload is malformed (=not authenticated properly) or if
-the [`AuthRequest.user_id`] of the `request` is not in the list of users that can hold a Gradecoin account
 
-# Authentication Process
-- Gradecoin's Public Key (`gradecoin_public_key`) is listed on moodle.
-- Gradecoin's Private Key (`gradecoin_private_key`) is loaded here
+Lets a user to authenticate themselves to the system.
+Only people who are enrolled to the class can open Gradecoin accounts.
+This is enforced with your Student ID and a one time password you will receive.
 
-- Student picks a short temporary key (`k_temp`)
-- Creates a JSON object (`auth_plaintext`) with their `metu_id` and `public key` in base64 (PEM) format (`S_PK`):
+# Authentication Process
+- Gradecoin's Public Key (`gradecoin_public_key`) is listed on our Moodle page.
+- You pick a short temporary key (`k_temp`)
+- Create a JSON object (`auth_plaintext`) with your `metu_id` and `public key` in base64 (PEM) format (`S_PK`) [reference](https://tls.mbed.org/kb/cryptography/asn1-key-structures-in-der-and-pem)
+```json
 {
-    student_id: "e12345",
-    passwd: "15 char secret"
-    public_key: "---BEGIN PUBLIC KEY..."
+    "student_id": "e12345",
+    "passwd": "15 char secret",
+    "public_key": "---BEGIN PUBLIC KEY..."
 }
+```
+
+- Pick a random IV.
+- Encrypt 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`. Encode this with base64.
+- The temporary key you have picked `k_temp` is encrypted using RSA with OAEP padding scheme
+using SHA-256 with `gradecoin_public_key`, giving us `key_ciphertext`. Encode this with base 64.
+- The payload JSON object (`auth_request`) can be serialized now:
 
-- 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?
-- The temporary key student has picked `k_temp` is encrypted using RSA with OAEP padding scheme
-using sha256 with `gradecoin_public_key` (TODO base64? same as above), giving us `key_ciphertext`
-- The payload JSON object (`auth_request`) can be JSON serialized now:
+```json
 {
-    c: "auth_ciphertext"
-    key: "key_ciphertext"
+    "c": "auth_ciphertext",
+    "iv": "hexadecimal",
+    "key": "key_ciphertext"
 }
+```
 
-## Gradecoin Side
-
-- 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
-- With `temp_key`, we can AES 128 Cbc Pkcs7 decrypt the `auth_request.c`, giving us
-auth_plaintext
-- The `auth_plaintext` String can be deserialized to [`AuthRequest`]
-- We then verify the payload and calculate the User fingerprint
-- Finally, create the new [`User`] object, insert to users HashMap `<fingerprint, User>`
-
-
+If your authentication process was valid, you will be given access and your public key fingerprint that is your address.
