What is encryption?

• A process of altering data to make it appear random

• A method of storing data in binary format

• A way of compressing data to save storage space

• A technique for transmitting data over the internet

What is a cryptographic key?

• A set of mathematical values used to encrypt and decrypt data

• A physical key used to lock and unlock encrypted data

• A string of characters used to represent binary data

• A protocol for secure communication over the internet

Why is data encryption necessary?

• To ensure privacy and protect sensitive data

• To increase the speed of data transmission

• To prevent data breaches caused by weak passwords

• To comply with industry and government regulations

What is a brute force attack?

• An attempt to determine the decryption key by making millions of guesses

• A method of encrypting data using a combination of substitution and transposition ciphers

• A protocol for secure communication over the internet

• A cryptographic algorithm used for data encryption

What is symmetric encryption?

• A type of encryption where the same key is used for both encryption and decryption

• A type of encryption where different keys are used for encryption and decryption

• A type of encryption that uses a combination of substitution and transposition ciphers

• A type of encryption that is resistant to brute force attacks

What is the primary purpose of encryption?

• To increase data storage capacity

• To prevent unauthorized access to information

• To speed up data transmission
