Understanding Passwords

What is the benefit of salting password hashes?

  • A Full encryption in the SAM database
  • B Strong encryption algorithms are enforced
  • C Rainbow Tables cannot be used to crack the password
  • D Dictionary password guessing attacks can't be used
Explanation

A unique salt changes the resulting hash even when two users choose the same password, making precomputed rainbow-table lookups ineffective for cracking those passwords at scale.
