More About cryptography

Long ago, people used simple codes to hide their messages. They would change letters or use symbols. This made it hard for others to read. Now, we use computers to make codes that are much harder to break.

In our daily lives, we use cryptography when we log in to games or buy toys online. It keeps our info safe from bad guys. We can trust that our secrets stay secret!

In the future, cryptography will keep getting better. As tech grows, so will the codes. This will help keep our world safe and our secrets safe too!
