.Question 17What is the purpose of a salt in password hashing?1 pointTo add flavor to the hashed password.To store the password in plain text in the database.To add random data to the password before hashing, making it more difficult for attackers to use precomputed lookup tables to crack the hashed password.To add a secret key to the password before hashing, making it more difficult for attackers to crack the hashed password.

How does the principle of "password salting" contribute to password security?a.It adds flavor to passwords for better user experienceb.It involves seasoning passwords with additional characters to make them more complexc.It prevents rainbow table attacks by adding a random value to each password before hashingd.It requires users to change their passwords regularly

Which is true in using salting in hashing for passwords? salting impedes the use of weak passwords.salting makes it more difficult to guess online passwords with brute force.salting makes cracking brute force offline of password hashes more difficult.salting guarantees that hash collisions doesn’t occur.

In the context of hash tables, what is the primary purpose of double hashing?Group of answer choicesTo provide an alternative hash function in case of collisions.To reduce the load factor of the hash table.To calculate the initial hash value for a key.To determine the size of the hash table.

What is a password hash?Select one:a.A representation of a password that is transmitted over a networkb.A representation of a password that is encrypted using a keyc.A representation of a password that is stored in a system or networkd.A representation of a password that is stored in a file
