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.

Lecture on password encryption, hashing, and bcrypt

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.
