Question27Max. score: 2.00Of the following, which statement correctly describes the difference between a secure cipherand a secure hash?A hash produces a variable output for any input size; a cipher does not.A cipher produces the same size output for any input size; a hash does not.A hash can be reversed; a cipher cannot.A cipher can be reversed; a hash cannot.

Which of the following statements best encapsulates the basic principles of a cryptographic hash function?Group of answer choicesA cryptographic hash function generates a unique identifier for each unique input, can produce output of varying lengths based on the complexity of the input, and maintains a consistent hash value for similar inputs to ensure easy retrieval.A cryptographic hash function is reversible, meaning that with enough computing power, the original input can be retrieved from its hash, and it produces the same hash for any given input of similar size.A cryptographic hash function can easily convert the hash value back to its original input, always produces variable-sized output depending on the length of the input, and a small change in the input results in a minor change in the output hash.A cryptographic hash function is a one-way function that cannot easily be reversed, always produces a fixed-size output regardless of the input size, and a small change in the input results in a drastically different output hash.

Which property differentiates between MAC and Hash?MAC does not provide Integrity.Hash provides Authenticity and Integrity both.MAC provides Authenticity and Integrity both.Both have same properties.

Which two statements about encryption are correct? (Choose two.)

Which codes must be viewed as the hash functions that have two functionally distinct inputs, that is, a secret key and a message and produces a fixed size of the output?AMessage Authentication codesBMessage codesCAuthentication CodesDNone of the above.
