MD2 Encryption methods: Fundamentals of cryptography

Question 1

Cryptography

Answer 1

Cryptography is the process of transforming information into a form that unintended readers can’t understand.

Question 2

Encryption

Answer 2

Encryption takes that information and scrambles it into an unreadable form, known as ciphertext

Question 3

Decryption

Answer 3

We then use decryption to unscramble the ciphertext back into plaintext form, making it readable again.

Question 4

Cryptographic key

Answer 4

A cryptographic key is a mechanism that decrypts ciphertext.

Every form of encryption relies on both a cipher and key to secure the exchange of information.
