-POST request to `/register` endpoint
-
-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 (e123456) and a one time password you will receive.
-
-# Authentication Process
-
-> The bytes you are sending over the network are all Base64 Encoded
-
-- Gradecoin's Public Key (`gradecoin_public_key`) is listed on our Moodle page and [here](/gradecoin.pub). Download and load it it to your client.
-- Create a JSON object (`P_AR`) with your `metu_id` ("e"+`6 chars`) 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": "e123456",
-    "passwd": "15 char secret",
-    "public_key": "---BEGIN PUBLIC KEY..."
-}
-```
-
-## Cipher Initialization
-
-> Since we are working with AES-128, both key and IV should be 128 bits (or 16 hexadecimal characters)
-
-- Pick a short temporary key (`k_temp`)
-- Pick a random IV [1](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Initialization_vector_(IV)) [2](https://en.wikipedia.org/wiki/Initialization_vector) (`iv`).
-
-## Encryption
-- Encrypt the serialized string of `P_AR` with 128 bit block [AES](https://en.wikipedia.org/wiki/Initialization_vector) in [CBC](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#CBC) mode with [Pkcs7 padding](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Padding) using the temporary key (`k_temp`), the result is `C_AR`. Encode this with base64.
-- The temporary key you have picked `k_temp` is encrypted using RSA with [OAEP](https://en.wikipedia.org/wiki/Optimal_asymmetric_encryption_padding) padding scheme using SHA-256 with `gradecoin_public_key`, giving us `key_ciphertext`. Encode this with base64.
-- Base64 encode the IV (`iv`) as well.
-
-{% tidbit() %}
-The available tools and libraries might warn you about how using the primitives given above are "hazardous". They are, crypto is hard.
-{% end %}
-
-- The payload JSON object (`auth_request`) can be serialized now:
-
-```json
-{
-    "c": "C_AR",
-    "iv": "iv",
-    "key": "key_ciphertext"
-}
-```
-
-If your authentication process was valid, you will be given access and your public key fingerprint that is your address.
-You can now sign [JWTs](@/JWT.md) to send authorized transaction requests.
