What is the minimum salt length NIST specifies for stored passwords, and what does the salt achieve?

• Identity

1. 32 bits; it ensures two accounts with the same password do not share a hash
2. 64 bits; it replaces the need for a cost factor
3. 16 bits; it slows the hash function
4. 128 bits; it encrypts the stored hash
