Technical Challenge - Practical Applications

We would like you to fork this repository. This will help us get an understanding of your operational skills, no matter which technology stack is used.

Important notes:

• There is no specific time limitations, so you can go at your own pace.
• Once you have completed this part of the challenge, please fill out the Google Form that is mentioned at the bottom of this page with your forked repository.

Overview

This repository contains an API skeleton where you can add the code, which is the auth_api folder. Use the language of your preference.

You need to complete a functionality in our API that provides a basic authentication.

The API has 2 missing endpoints. The first endpoint receives a username and password. When these parameters are correct it returns a JWT token; otherwise it should return a 403 HTTP error message.

You will have a read only database with these access:

engine	mysql
user	secret
password	jOdznoyH6swQB9sTGdLUeeSrtejWkcw
endpoint	sre-bootcamp-selection-challenge.cabf3yhjqvmq.us-east-1.rds.amazonaws.com
port	3306
DB	bootcamp_tht

In the database three valid users with their passwords are stored:

Table users

username	password	salt	role
admin	encrypted-password	F^S%QljSfV	admin
noadmin	encrypted-password	KjvFUC#K*i	editor
bob	encrypted-password	ykptwoT=M(	viewer

Passwords in plain text:

username	password
admin	secret
noadmin	noPow3r
bob	thisIsNotAPasswordBob

Passwords have appended the salt value and hashed with the SHA512 Algorithm. If the username and password combination is valid, you should return a JWT Token with the role in the payload of the token.

You should use this 256 bit secret to encrypt your token: my2w7wjd7yXF64FIADfJxNs1oupTGAuW

curl -d "username=admin&password=secret" http://localhost:8000/login
{
  "data": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"
}

For the second endpoint you must use the generated token to access a restricted area:

curl -H 'Accept: application/json' -H "Authorization: Bearer ${TOKEN}" localhost:8000/protected
{
  "data": "You are under protected data"
}

Coding

• Complete the following endpoints.
  • /login
  • /protected
• Make sure your tests are passing.
• Add missing tests. Feel free to add any additional tests that you think are valuable.
• As mentioned above, you may work in the language of your choice. Please pick one from the list of available languages:
  • Python
  • Java
  • NodeJS

Docker

• Dockerize the application located in src
• Push it to a public image in DockerHub tagged as wize-<firstName>-<lastName>:latest
• Application should run in port 8000
