How To Safely Store A Password

Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt. Use bcrypt.

Why Not {MD5, SHA1, SHA256, SHA512, SHA-3, etc}?

These are all general purpose hash functions, designed to calculate a digest of huge amounts of data in as short a time as possible. This means that they are fantastic for ensuring the integrity of data and utterly rubbish for storing passwords.

bcrypt Solves These Problems

How? Basically, it’s slow as hell. It uses a variant of the Blowfish encryption algorithm’s keying schedule, and introduces a work factor, which allows you to determine how expensive the hash function will be.

Coffee Warehouse API

You've been tasked to build a RESTful API that will help serve and manage data of coffee at a warehouse. Another team will be depending this API in building a front-end application to interact with it.

Draft a routes overview table or list of how you plan on designing your API and submit it to the senior developer for confirmation.

An example can be found on buzzword-bingo: https://github.com/devleague/Buzz-Word-Bingo/blob/master/README.md

We'll be depending on you to build a well-designed RESTful API for our front-end team to work with. Good route naming conventions will be key in providing a simple yet effective API for others to work with.

1. Functions

   • def
   • Why we use functions
   • return statements
   • global vs. local variables
   • arguments pass by reference
   • tuple arguments ???
   • keyword and default arguments

2. Create a python script

This exercise can be performed in Bash, CMD, or Powershell

Follow the instructions

Build a bash-exercise.sh file in your HOME directory.

Do your work in the scripts.sh file. Make sure your bash-exercise.sh is executable. You may comment out lines respective to each task to avoid overwriting/errors.

1. Build a folders directory and inside, build 10 new directories with the incremented name of dir. We should get something like ./folders/dir1, ./folders/dir2 and so forth.
2. Create a projects directory in ./folders/dir1 and build a README.md file in the projects dir.
