Explain salting and its usage.

1.	Explain salting and its usage.
Answer» Spring Security automatically applies salting since version 3.1. Salting is the process of combining random data with a password before password hashing. SALT improves hashing by increasing its uniqueness and complexity without increasing the requirements for users, thereby reducing password attacks. HASHED passwords are then stored in a database, ALONG with salt. Your application will be protected from Dictionary-Attack by using salting. With Salt, you can ADD an extra string to the password to make it more difficult for HACKERS to crack it.
