Question

Select a correct statement regarding a hashing process.

a) It is used for authentication.
b) It is reversible.
c) It is not necessary to use a hashing process in creating a digital signature.
d) The outcome is a message digest.

Answer 1

a) It is used for authentication.

Step-by-step explanation:

Hashing is a process of transforming a single key into another value. It generates the values using a mathematical algorithm. the outcome of this process is a hash value or a hash.

The hashing process is used for authentication.

The hashing process is not reversible.

The hashing process is used to create the digital signature.

The outcome of the hashing process is the hash value, not a message.
