Question 1

What is cryptography?

Accepted Answer

Cryptography is like a secret code used to keep messages safe. It helps make sure only the right people can read or understand a message.

Question 2

Why is cryptography important?

Accepted Answer

Cryptography is important because it protects our personal information, like passwords and bank details, from being stolen. It's like locking your diary so no one else can read it.

Question 3

How does cryptography work?

Accepted Answer

Cryptography uses special rules to turn a message into a secret code. Only someone with the right key, like a secret password, can change the code back into the original message.

Question 4

What is a key in cryptography?

Accepted Answer

A key is like a special password that lets you unlock a secret message. Without the key, the message stays a secret.

Question 5

Accepted Answer

Yes, anyone can use cryptography! Many apps and websites use it to keep your data safe, and you don't even have to think about it.

Question 6

What's an example of cryptography in real life?

Accepted Answer

When you send a message using an app like WhatsApp, cryptography keeps it safe. This means only the person you're chatting with can see what you said.

Question 7

Is cryptography only for computers?

Accepted Answer

No, cryptography can be used for any kind of secret code, even ones written on paper. However, computers are really good at using it because they can do it very fast.

Question 8

What’s the difference between encrypted and unencrypted?

Accepted Answer

An encrypted message is in secret code, so it’s safe. An unencrypted message is like writing your message on a postcard for anyone to see.

Accepted Answer

Sometimes people can find ways to break cryptographic codes, but it's usually very hard and takes a long time. That's why cryptography is always getting better!

Question 14

What does 'decrypt' mean?

Accepted Answer

Decrypting means turning a secret code back into the original message. It's like solving a puzzle to discover what the hidden message says.
