What is the purpose of adding salt to the password hashing process?
- to decrease password complexity
- to increase the length of a password
- to make hashed passwords deterministic
- to create a unique hash for every password
Explanation: Because of the deterministic nature of the hash function, hashed passwords are not unique. The same password always produces the same hash even if the password is created by different users. The salting process adds random data to the input of the hash function to guarantee a unique, nondeterministic output.
