Explanation:
Cryptographic hash functions are designed to take a string of any length as input and produce a fixed- length message digest, not a message digest of arbitrary length.
A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone. These one-way hash functions have been called "the workhorses of modern cryptography". The input data is often called the message, and the hash value is often called the message digest or simply the digest.
The ideal cryptographic hash function has four main properties:
it is easy to compute the hash value for any given message
it is infeasible to generate a message from its hash
it is infeasible to modify a message without changing the hash
it is infeasible to find two different messages with the same hash.
Incorrect Answers:
B: It is true that it is computationally infeasible to construct two different messages with the same digest.
C: It is true that it converts a message of arbitrary length into a message digest of a fixed length.
D: It is true that given a digest value, it is computationally infeasible to find the corresponding message.
