A brute-force attack is launched to obtain which of the following?

A.
Encryption keys

B.
A public algorithm

C.
A public key

D.
Ciphertext

Explanation:
A brute-force attack is when an attacker tries all possible solutions
until the correct one is uncovered. This can be trying to find a sequence of
characters that represent a valid password or all possible key values within a
keyspace. Cryptanalysis is a category of hacking that tries to break an encryption
system, usually by uncovering the selected keys. Once the key is uncovered then any
data encrypted using that key can be deciphered and read.
