Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

Answer:
D. 256
Explanation:
Given
Required
Determine the maximum number of output
To get the required value, we make use of the following:
Where n is the bits of the opcode.
i.e.
Substitute 8 for n in
<em>Hence, option D answers the question</em>
Answer: Doxing
Explanation: Doxing which is also referred as doxxing is defined as the revealing or publishing of the private records or information to the public.It is considered as the illegal practice which is base on the the internet service.The publicizing of the private data or confidential information is punishable offence.
Other options are incorrect because filtering is the elimination of the not required content, spamming is the activity of sending undesired bulk messages and hacking is the attacking of the system using false means to corrupt and steal data.Thus the correct option is doxing.
