Secure Hash Standard

Okay kiddo, have you ever done a puzzle where you have to find two pieces that fit perfectly together? The Secure Hash Standard (also called SHA) is like a puzzle for computers.

When you use a computer or the internet, there are lots of ways for bad people to try to steal your information, like your passwords or credit card numbers. One way to stop them is to use a secret code, which is called a hash.

A hash is like a puzzle piece that fits your password perfectly. Only your password will fit into the puzzle piece! So, when you put your password through a hash, the computer turns your password into a bunch of jumbled letters and numbers that only work with your password.

But, just like with a puzzle, sometimes people can guess which puzzle piece should fit with your password. To make sure that doesn't happen, everyone uses the same type of hash puzzle piece. This way, everyone's puzzle pieces look different, even if the password is the same.

That's where the Secure Hash Standard comes in. It's a set of rules for how to make the puzzle pieces, so that no one can guess which piece is yours. It's like having a rulebook for a puzzle contest, so that everyone has to follow the same rules.

This way, your passwords are safe and secure, and bad people can't guess them. The Secure Hash Standard keeps everyone's information safe and private, just like you should keep your toys safe and private!
