How does salting enhance password security, and why is it important to use stronger hash functions?
Salting is a technique used to enhance password security in web applications. It involves adding a random value, known as a salt, to each password before hashing it. This salt is then stored alongside the hashed password in the database. The primary purpose of salting is to defend against precomputed rainbow table attacks, where an
