Which of the following describes a rainbow table?

A rainbow table is a password hacking tool that uses a precomputed table of reversed password hashes to crack passwords in a database.

What is a rainbow table and how is it used?

A rainbow table is a database that is used to gain authentication by cracking the password hash. It is a precomputed dictionary of plaintext passwords and their corresponding hash values that can be used to find out what plaintext password produces a particular hash.

What is a rainbow table cryptographic attack?

What Does Rainbow Table Attack Mean? A rainbow table attack is a type of hacking wherein the perpetrator tries to use a rainbow hash table to crack the passwords stored in a database system. A rainbow table is a hash function used in cryptography for storing important data such as passwords in a database.

Why is it called a rainbow table?

In the rainbow table the precomputed dictionary of pairs key-ciphertext is compressed in chains. Every step in chain is done using different commpression function. And the table has a lot of chains, so it looks like a rainbow.

Which of these describes how a rainbow forms?

Rainbows are formed when light from the sun is scattered by water droplets (e.g. raindrops or fog) through a process called refraction. Refraction occurs when the light from the sun changes direction when passing through a medium denser than air, such as a raindrop.

How are rainbows described?

A rainbow is a multicolored arc made by light striking water droplets. The most familiar type rainbow is produced when sunlight strikes raindrops in front of a viewer at a precise angle (42 degrees). Rainbows can also be viewed around fog, sea spray, or waterfalls.

What is a rainbow table quizlet?

A rainbow table is a table of common passwords hashed using a common cryptographic hash function, like SHA1. When a password DB is compromised, a rainbow table can be used to brute force attack the DB.

What is the reason for using rainbow tables quizlet?

What is the reason for using rainbow tables? pre-computed hashes that are mapped to plaintext passwords to speed up the process of obtaining the passwords from stored hashes.

How big is a rainbow table?

A rainbow table stores all the one-way hashes of plaintext passwords from 1 character in length to 7 or maybe 8 characters in length. (An 8 character rainbow table for a simple hashing algorithm will take up to 32 Petabytes of database space to store!).

Is rainbow table a dictionary attack?

Rainbow table attacks are similar to dictionary attacks, but they use a rainbow table instead of a word list. Rainbow tables are pre-computed listings. Although these are similar to dictionary attacks, they need less computing power.

Is rainbow table brute force?

The main difference between a brute force attack and a rainbow table attack is that there is precomputed data involved with a rainbow table when trying to crack passwords whereas there is no precomputed data when a brute force is to be performed.

What is RainbowCrack used for?

RainbowCrack is a computer program which generates rainbow tables to be used in password cracking. RainbowCrack differs from "conventional" brute force crackers in that it uses large pre-computed tables called rainbow tables to reduce the length of time needed to crack a password drastically.

What is a rainbow table quizlet?

A rainbow table is a table of common passwords hashed using a common cryptographic hash function, like SHA1. When a password DB is compromised, a rainbow table can be used to brute force attack the DB.

What is the reason for using rainbow tables quizlet?

What is the reason for using rainbow tables? pre-computed hashes that are mapped to plaintext passwords to speed up the process of obtaining the passwords from stored hashes.

What statement correctly defines what a rainbow table is in relation to password attacks?

What statement correctly defines what a rainbow table is in relation to password attacks? A rainbow table is a compressed representation of cleartext passwords that are related and organized in a sequence.

Which of the following is required to build a rainbow table?

Constructing a rainbow table requires two things: a hashing function and a reduction function.

What role do rainbow tables serve in digital forensics examinations?

Rainbow tables serve what purpose for digital forensics examinations? Rainbow tables contain computed hashes of possible passwords that some password-recovery programs can use to crack passwords.

Is a hash table the same as rainbow table?

Hash tables are great very simple passwords. (For example, you might use a hash table to scan a database for passwords that match one of the top 10,000 most commonly used passwords. Rainbow tables, on the other hand, are great for trying to crack the hashes of tougher or more complex passwords.

What is the advantage of a rainbow table over other password attacks?

What are the three advantages of a rainbow table over other password attacks? 1) Can be used repeatedly to attack other passwords. 2) Faster than dictionary attacks. 3) Amount of memory needed on attacking machine is greatly reduced.
