What is ECB?

ECB is like having a special kind of translator who helps you write messages that only certain people can read.

Imagine you have a toy box full of letters, each letter has its own secret code. When you want to send a message, you use this special translator to change your words into these coded letters. But here's the fun part: if someone wants to read your message, they need another special translator that turns those coded letters back into real words.

This is how ECB, or the Electronic Codebook, works in the world of secrets and messages. It’s a way to make sure only the right people can understand what you're saying, just like having a secret language with your best friend at school.

Think of ECB as a kind of invisible ink. When you write using this ink, your message is hidden and can't be read by others unless they have the special tool (like a warm lamp) to reveal the message. In this case, your translator acts like that special tool, it helps you hide your messages and bring them back into view when needed.

So ECB makes sending secret messages simple and fun, just like playing with invisible ink in class!
