Which of the following is assured by the use of a hash?
Integrity
Availability
Authentication
Confidentiality
By adding a hash to a password that controls information you are trying to protect, you are minimizing the risk of data alteration and maintaining the integrity of the data. Edit: someone changed this incorrectly to confidentiality. Please do not alter answers without comprehensive understanding of the subject. -- Better yet, reference the appropriate sources for the information so answers can be verified. I, for one, will not be taking your word for it. Not any of you. I see too much stupid in these explanations. NOTE: Because this question is in the 'password cracking' section, people are incorrectly answering 'confidentiality'. The hash of a password does protect the confidentiality of the password but that is not what the question is asking. Hashes in general ensure Integrity.
