what are two properties of a cryptographic hash function? (choose two.)\nthe input for a particular hash algorithm has to have a fixed size.\ncomplex inputs will produce complex hashes.\nhash functions can be duplicated for authentication purposes.\nthe output is a fixed length.\nthe hash function is one way and irreversible.

Answer

Brief Explanations:

  1. One - wayness: A cryptographic hash function is one - way and irreversible. Given a hash value, it is computationally infeasible to find the original input.
  2. Fixed - length output: Regardless of the size of the input data, the output of a hash function has a fixed length. For example, SHA - 256 always produces a 256 - bit hash value.

Answer:

The output is a fixed length. The hash function is one way and irreversible.
