WebFeb 25, 2024 · Recap. A cryptographic salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords. Salts help us mitigate hash table attacks by forcing attackers to re-compute them using the salts for each user. WebJul 29, 2024 · The NT hash is simply a hash. The password is hashed by using the MD4 algorithm and stored. The NT OWF is used for authentication by domain members in both Windows NT 4.0 and earlier domains and in Active Directory domains. Neither the NT hash nor the LM hash is salted.
