Okay kiddo, so imagine you have a secret message that you want to send to your friend, but you don't want anyone else to be able to read it. One way to do this is by using something called encryption. Think of encryption like a secret code that only you and your friend know how to decode.
Now, coppersmith is a computer algorithm that helps with encryption. It's named after a man named Don Coppersmith who came up with the idea. Basically, the coppersmith algorithm helps to make encryption stronger and harder to crack.
When you use coppersmith, you take your secret message and put it through a mathematical formula. This formula creates a code that looks like a bunch of random letters and numbers to anyone who tries to read it. But, your friend who knows the formula will be able to decrypt the code and read your secret message.
The reason coppersmith is important is because it helps to make sure that only the people who are supposed to be able to read a message can do so. Without encryption, anyone could potentially intercept and read your messages, which would not be good for keeping your secret safe.
So, in summary, coppersmith is a computer algorithm that helps with encryption. It makes messages harder to read by creating a secret code that only the intended recipient can decode.
