Storyboard Text

  • Type password, and the company makes a string of numbers. Hackers can reverse to find password. Decent

  • Hash: 01dfae6e5d4d90d9892622325959afbe
  • Salt: 7050461
  • First, the company adds a hash and salt to your password.
  • Encryption key
  • Plain Text: Username: qwertyuiop Password: Pupp13s!
  • Typing in my password, p...a...s...s...w...o...r...d
  • Sometimes, security systems fail. You're responsible for your own Internet safety.
  • Let's watch Jimmy and the mistakes he makes.
