Imagine you are sending a confidential document to your colleague. What is the purpose of encrypting this document before sending it?
To increase the storage space on the device holding the document
To encode the document so only your colleague can access its contents
To enhance the speed of the document's transmission over the internet
To make the transmission of the document more expensive
What is plaintext?
A tool used to hack data
The original, readable data that needs protection
A type of encryption algorithm
The encrypted form of data
Which of the following is NOT an encryption algorithm?
Data Encryption Standard (DES)
Rivest-Shamir-Adleman (RSA)
Advanced Encryption Standard (AES)
HyperText Transfer Protocol (HTTP)
What is a key in the context of encryption?
A physical device used to unlock encrypted data
A software that generates random data
A password that users must remember
A piece of information used by the encryption algorithm
What is symmetric key encryption?
A method where different keys are used for encryption and decryption
A technique that does not require a key
A method where the same key is used for both encryption and decryption
A type of encryption that is easily broken
What is asymmetric key encryption also known as?
Dual-key encryption
Public-key encryption
Private-key encryption
Single-key encryption
What is ciphertext?
The original, readable data
A tool for breaking encryption
A type of encryption algorithm
The encrypted form of the plaintext
What is decryption?
The process of converting ciphertext back into plaintext
A method to enhance encryption
The process of doubling the encryption
Creating a duplicate of the original data
Why is encryption crucial when sending confidential emails?
For making email transmission slower
