What are two properties of a cryptographic hash function? (Choose two.)
- Complex inputs will produce complex hashes.
- Hash functions can be duplicated for authentication purposes.
- The hash function is one way and irreversible.
- The input for a particular hash algorithm has to have a fixed size.
- The output is a fixed length.
Explanation: A cryptographic hash function should have the following properties:
- The input can be any length.
- The output has a fixed length.
- The hash value is relatively easy to compute for any given input.
- The hash is one way and not reversible.
- The hash is collision free, meaning that two different input values will result in different hash values
