NEW QUESTION: 2
The primary purpose for using one-way hashing of user passwords within a password file is which of the following?
A. It minimizes the amount of processing time used for encrypting passwords.
B. It prevents an unauthorized person from reading the password.
C. It prevents an unauthorized person from trying multiple passwords in one logon attempt.
D. It minimizes the amount of storage required for user passwords.
Answer: B
Explanation:
The whole idea behind a one-way hash is that it should be just that - one-way. In other words, an attacker should not be able to figure out your password from the hashed version of that password in any mathematically feasible way (or within any reasonable length of time).
Password Hashing and Encryption In most situations , if an attacker sniffs your password from the network wire, she still has some work to do before she actually knows your password value because most systems hash the password with a hashing algorithm, commonly MD4 or MD5, to ensure passwords are not sent in cleartext.
Although some people think the world is run by Microsoft, other types of operating systems
are out there, such as Unix and Linux. These systems do not use registries and SAM
databases, but contain their user passwords in a file cleverly called "shadow." Now, this
shadow file does not contain passwords in cleartext; instead, your password is run through
a hashing algorithm, and the resulting value is stored in this file.
Unixtype systems zest things up by using salts in this process. Salts are random values
added to the encryption process to add more complexity and randomness. The more
randomness entered into the encryption process, the harder it is for the bad guy to decrypt
and uncover your password. The use of a salt means that the same password can be
encrypted into several thousand different formats. This makes it much more difficult for an
attacker to uncover the right format for your system.
Password Cracking tools
Note that the use of one-way hashes for passwords does not prevent password crackers
from guessing passwords. A password cracker runs a plain-text string through the same
one-way hash algorithm used by the system to generate a hash, then compares that
generated has with the one stored on the system. If they match, the password cracker has
guessed your password.
This is very much the same process used to authenticate you to a system via a password.
When you type your username and password, the system hashes the password you typed
and compares that generated hash against the one stored on the system - if they match,
you are authenticated.
Pre-Computed password tables exists today and they allow you to crack passwords on Lan
Manager (LM) within a VERY short period of time through the use of Rainbow Tables. A
Rainbow Table is a precomputed table for reversing cryptographic hash functions, usually
for cracking password hashes. Tables are usually used in recovering a plaintext password
up to a certain length consisting of a limited set of characters. It is a practical example of a
space/time trade-off also called a Time-Memory trade off, using more computer processing
time at the cost of less storage when calculating a hash on every attempt, or less
processing time and more storage when compared to a simple lookup table with one entry
per hash. Use of a key derivation function that employs a salt makes this attack unfeasible.

Today's password crackers:
Meet oclHashcat. They are GPGPU-based multi-hash cracker using a brute-force attack
(implemented as mask attack), combinator attack, dictionary attack, hybrid attack, mask
attack, and rule-based attack.
This GPU cracker is a fusioned version of oclHashcat-plus and oclHashcat-lite, both very
well-known suites at that time, but now deprecated. There also existed a now very old
oclHashcat GPU cracker that was replaced w/ plus and lite, which - as said - were then
merged into oclHashcat 1.00 again.
This cracker can crack Hashes of NTLM Version 2 up to 8 characters in less than a few
hours. It is definitively a game changer. It can try hundreds of billions of tries per seconds
on a very large cluster of GPU's. It supports up to 128 Video Cards at once.
I am stuck using Password what can I do to better protect myself?
You could look at safer alternative such as Bcrypt, PBKDF2, and Scrypt.
bcrypt is a key derivation function for passwords designed by Niels Provos and David
Mazieres, based on the Blowfish cipher, and presented at USENIX in 1999. Besides
incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function:
over time, the iteration count can be increased to make it slower, so it remains resistant to
brute-force search attacks even with increasing computation power.
In cryptography, scrypt is a password-based key derivation function created by Colin
Percival, originally for the Tarsnap online backup service. The algorithm was specifically
designed to make it costly to perform large-scale custom hardware attacks by requiring
large amounts of memory. In 2012, the scrypt algorithm was published by the IETF as an
Internet Draft, intended to become an informational RFC, which has since expired. A
simplified version of scrypt is used as a proof-of-work scheme by a number of
cryptocurrencies, such as Litecoin and Dogecoin.
PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function that is
part of RSA Laboratories' Public-Key Cryptography Standards (PKCS) series, specifically
PKCS #5 v2.0, also published as Internet Engineering Task Force's RFC 2898. It replaces
an earlier standard, PBKDF1, which could only produce derived keys up to 160 bits long.
PBKDF2 applies a pseudorandom function, such as a cryptographic hash, cipher, or HMAC
to the input password or passphrase along with a salt value and repeats the process many
times to produce a derived key, which can then be used as a cryptographic key in
subsequent operations. The added computational work makes password cracking much
more difficult, and is known as key stretching. When the standard was written in 2000, the
recommended minimum number of iterations was 1000, but the parameter is intended to be increased over time as CPU speeds increase. Having a salt added to the password reduces the ability to use precomputed hashes (rainbow tables) for attacks, and means that multiple passwords have to be tested individually, not all at once. The standard recommends a salt length of at least 64 bits.
The other answers are incorrect:
"It prevents an unauthorized person from trying multiple passwords in one logon attempt." is incorrect because the fact that a password has been hashed does not prevent this type of brute force password guessing attempt.
"It minimizes the amount of storage required for user passwords" is incorrect because hash algorithms always generate the same number of bits, regardless of the length of the input. Therefore, even short passwords will still result in a longer hash and not minimize storage requirements.
"It minimizes the amount of processing time used for encrypting passwords" is incorrect because the processing time to encrypt a password would be basically the same required to produce a one-way has of the same password.
