40-bit encryption

Hey kiddo! So, when you send a secret message to someone on the internet, we need to make sure no one else can read it. We do this by using something called encryption, which is like putting your message in a secret code that only you and the person you're talking to can understand.

Now, 40-bit encryption is one way we can do this. It means there are 40 digits in the secret code that we use to scramble the message.

Think of it like a secret handshake that you can only do with your best friend. You both know exactly how to do it, but no one else does. That's kind of what encryption is like.

But, 40-bit encryption isn't very strong compared to other types of encryption. It's kind of like having a really simple secret handshake that someone else might catch on to if they spy on it. So we need to use stronger kinds of encryption for really important information.
