Crypotography

What is the main purpose of cryptography?

• To increase the storage space on devices

• To encode information so only authorized individuals can understand it

• To make data transmission over the Internet faster

• To make it easier to share information on social media

Why is it important to encrypt sensitive information before sending it over the Internet?

• To improve the website's loading speed

• To make the data look more interesting

• To prevent unauthorized access and understanding of the information

• To comply with social media policies

Why is encryption considered important for security?

• It makes it easier to share files

• It reduces the cost of data storage

• It ensures only authorized users can access the information

• It makes data transfer faster

What is required to decrypt an encrypted message?

• A special software

• The correct key

• Permission from the Internet service provider

• A faster computer

What happens if you try to decrypt a message with the wrong key?

• It returns the original message anyway

• The original message is lost forever

• The message remains encrypted and unreadable

• The message decrypts slower

What is the result of encrypting data?

• Data becomes permanently altered

• Data is scrambled into an unreadable form

• Data transfer speeds are increased

• Data storage requirements are reduced

What role does a key play in cryptography?

• It locks the data so no one can access it

• It is used to encrypt and decrypt the message

• It serves as a password for internet access

• It increases the encryption speed

What is cryptanalysis?

• The process of decrypting messages without the key

• The process of encrypting messages

• A type of cryptography used by ancient civilizations

• The study of maps and crypts

What do cryptologists do?

• They break codes for government agencies

• They study ancient languages

• They design new encryption methods that are hard to crack

• They hack into secure networks

How do modern cryptologists contribute to data security?

• By breaking into secure systems to test their strength

• By developing software to bypass encryption

• By teaching others how to hack

• By creating complex encryption methods difficult to crack without a key
