Poly1305

Poly1305 is like a secret monster protector that lives inside your computer. It works with another monster protector named AES to make sure nobody steals your secrets when you send messages.

When you type a message or click on something, Poly1305 is like a bouncer that checks if you are allowed to do that. It's kind of like when you play with toys and your parents make sure you don't break anything. If the bouncer thinks you are trying to do something bad or sneaky, it will stop you and tell AES to seal the message in a secret box that nobody can open except you and your friends.

Poly1305 is really good at its job because it knows how to do lots of tricks with numbers. It uses math to scramble the message so nobody can read it, even if they try really hard. Then, when your friends get the message, Poly1305 and AES will work together to unscramble it so they can read it perfectly.

So, Poly1305 is like a secret monster bouncer that protects your messages by doing math tricks and working with AES to keep your secrets safe from sneaky people.
