Accepted Answer

Many people and companies use cryptography, such as banks, websites, and even your phone, to keep information safe.

Question 8

What is a cipher?

Accepted Answer

A cipher is like a special recipe used in cryptography. It tells us how to change the information into a code.

Question 9

Can cryptography be broken?

Accepted Answer

Sometimes people can figure out the code, but strong cryptography makes it very hard to crack.

Question 10

What is a code?

Accepted Answer

A code is a way of writing information in secret so only certain people can understand it.

Question 11

What is a digital signature?

Accepted Answer

What is symmetric encryption?

Accepted Answer

Symmetric encryption uses the same key to lock and unlock information. It's like using one key for both opening and closing your locker.

Question 15

What is asymmetric encryption?

Accepted Answer

Public key cryptography uses two keys: one for everyone to see and one just for you. It helps send messages securely even if people see the public key.

Question 20

Can kids learn about cryptography?

Accepted Answer

Yes, kids can learn about cryptography by playing games that use secret codes or by solving puzzles. It's a fun way to understand how we keep things safe.
