Question

Which of the following is the definition of keyspace? The range of values that construct a cryptosystem key. The process of applying an algorithm to cleartext (or plaintext) data, resulting in a ciphertext. Provides a stronger cryptographic result with a shorter key. Ensuring that only the intended recipient can read the data.

Answer 1

A

Step-by-step explanation:

A key space is a set of all arrangements of a key, when given a fixed key size.

It is the total number of possible values of keys in a cryptographic algorithm or other security measures such as a password.

A key which is a byte long (or 8 bits) would consist of 256 possible keys.
