๐ Topic Summary
Imagine you want to keep a secret message safe. Hashing is like putting your message through a one-way shredder โ you get a scrambled version (the hash), but you can't unscramble it to get the original message back. Salting is like adding a random ingredient to the shredder before you shred your message, making it even harder for someone to guess the original, even if they know how the shredder works! ๐ง In password security, we hash and salt passwords before storing them. This way, even if a hacker steals the database, they won't be able to easily read the actual passwords.

๐ Part B: Fill in the Blanks

Answers: salting, secure, rainbow table, one-way
๐ค Part C: Critical Thinking
Why is it important to use a different salt for each password instead of using the same salt for all passwords?
