What is a feature of a cryptographic hash function?Question 19Select one:The output has a variable length.The hash input can be calculated given the output value.The hash function is a one-way mathematical function.Hashing requires a public and a private key.

What is a hash function?Group of answer choicesA function that maps keys to unique integer values.A function that maps keys to their memory addresses.A function that maps keys to a fixed range of integer values.A function that maps keys to random integer values.

Explain different hashing functions with an example.

What is the primary purpose of a hash function in data structures?Group of answer choicesTo generate a unique key for a given inputTo reduce the size of dataTo divide data into fixed-size blocksTo sort the data

Define Hash Function. List out properties of Hash function.

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.
