ELI5: Explain Like I'm 5

OCB mode

Okay kiddo, let me explain what OCB mode means.

OCB mode is a super special way that computers can keep your information really safe when you send it over the internet. When you want to talk to someone far away on the internet, you need to send your information over there. And you want to make sure that nobody else can see or change your information while it goes there.

OCB mode helps by putting a secret code called a "key" on your information before you send it. This key is like a password that only you and the person you're talking to know. This way, nobody else can read your information because they don't know the secret code.

But it's not just about hiding your information from others. OCB mode also makes sure that nobody can pretend to be you and send bad information to the person you're talking to. It's like a secret handshake between two friends - you both know how it works, so you know it's really your friend and not someone else pretending to be them.

So, in summary, OCB mode is a special way that computers can keep your information safe and secret when you send it over the internet. It puts a secret code on your information that only you and the person you're talking to know, and it also makes sure that nobody can pretend to be you and mess up your conversation. It's like a really good secret code that nobody can crack!
