____ allow a user to control how encryption will work in a given cipher.
A) Padding
B) Modes
C) Message digests
D) MACs

Question

Quizplus · Accepted Answer

Modes of encryption determine how the cipher will operate, such as how it handles the data size, how the input data is broken into blocks, and how the blocks are combined and transformed. Different modes have different strengths and weaknesses, and users can choose the mode that best fits their security requirements. Padding (A) adds extra bits to a message to reach a certain block size, while message digests (C) create a fixed-length hash of the input data to ensure data integrity. MACs (D) create a tag that can be used to verify the authenticity and integrity of a message. However, none of these options allow the user to control how encryption will work in a given cipher.
