Can anyone break a cryptographic code?

Accepted Answer

Sometimes, if a person is very clever or if the code is not very strong, someone might break it. That's why it's important to use strong cryptography.

Question 10

Is cryptography only used by computers?

Accepted Answer

No, people have used cryptography for thousands of years, even before computers existed! They would use codes to send secret messages on paper.
