A software developer wants to prevent stored passwords from being easily decrypted. When the password is
stored by the application, additional text is added to each password before the password is hashed. This
technique is known as:

A.
Symmetric cryptography.

B.
Private key cryptography.

C.
Salting.

D.
Rainbow tables.

Explanation:
Salting can be used to strengthen the hashing when the passwords were encrypted. Though hashing is a oneway algorithm, it does not mean that it cannot be hacked. One method to hack a hash is though rainbow tables
and salt is the counter measure to rainbow tables. With salt a password that you typed in and that has been
encrypted with a hash will yield a letter combination other than what you actually type in when it is rainbow table
attacked.
