Question 1

What is the use of encryption?

Answer 1

Making sensitive data hard to read by attackers and unauthorized individuals
decryption needs a secret key

Question 2

What are the two types of encryption?

Answer 2

Symmetric and asymmetric

Question 3

What is hashing?

Answer 3

using an algorithm to convert plain text to unique fixed-length hash value

Question 4

What way can hackers hack a hashed password?

Answer 4

using brute force attack, trying to write all possible passwords until they find the correct one

Question 5

What key does symmetric encryption use?

Answer 5

Uses the same key to encrypt and decrypt data

Question 6

what key does asymmetric encryption use?

Answer 6

uses a pair of public and private keys, the key used to encrypt data cant be used to decrypt data

Question 7

When is asymmetric encryption best used?

Answer 7

accessing sites using HTTPS and electronic data signing solutions

Question 8

What is an example of encryption of data in transit?

Answer 8

HTTPS protects data being sent over a network
Protecting in transit protects from outside observers

Question 9
