Question 1

What is cryptography?

Accepted Answer

Cryptography is like secret writing. It helps us send messages to others that only they can read.

Question 2

Why do we need cryptography?

Accepted Answer

We need cryptography to keep our messages safe and private, just like when you use a lock to keep your bike secure.

Question 3

How does cryptography work?

Accepted Answer

Cryptography uses special codes to change messages, so only someone with the right key can read them.

Question 4

What is a cipher?

Accepted Answer

A cipher is like a secret code or a puzzle that changes our message into something only the right people can understand.

Question 5

What is a key in cryptography?

Accepted Answer

A key is like a secret password that helps you unlock the secret message.

Question 6

What is encryption?

Accepted Answer

Encryption is when we change a message to hide it. It means only special people with the right key can read it.

Question 7

What is decryption?

Accepted Answer

Decryption is when we change the secret message back to its normal form, like using a secret code to reveal a mystery.

Question 8

Why is a secret important in cryptography?

Accepted Answer

Secrets are important because they help protect our messages so that only those who are supposed to see them can understand them.

Question 9

What is an example of cryptography?

Accepted Answer

If someone finds out the secret key, they could read your messages. It's like if someone found your secret diary key.

Question 11

How can we make our keys strong?

Accepted Answer

We make keys strong by making them long and hard to guess, like having a lock with thousands of combinations.

Question 12

Accepted Answer

Secure communication means sending messages that only the right people can read, like passing notes in a secret code.

Question 13

Can cryptography keep things safe forever?

Accepted Answer

No, cryptography can't keep things safe forever, but it does make it much harder for anyone else to read your messages.

Accepted Answer

Public key cryptography is like having two keys: one to lock (or hide) the message and a special one to unlock it.

Question 15

Do we use cryptography every day?

Accepted Answer

Yes, we use cryptography every day, like when you chat online or your parents shop on the internet.

Question 16

Why can't everyone solve cryptography puzzles easily?

Accepted Answer

Cryptography puzzles are made really tricky on purpose, so only the right people with the right keys can solve them.

Question 17

What is a message called when it is in secret code?

Accepted Answer

A message in secret code is called 'encrypted.' It's like writing in a secret language only your friends understand.

Question 18

Can cryptography be used to keep photos safe online?

Accepted Answer

Yes, cryptography can keep photos safe online by scrambling them so only friends with the right key can see them.

Question 19

What is a digital signature?

Accepted Answer

A digital signature is like an online fingerprint. It shows that a message really is from the person who sent it.

Question 20

Is learning about cryptography important?

Accepted Answer

Yes, learning about cryptography is important because it helps us understand how to keep our information safe and private online.
