I was reading a few articles on salts and password hashes and a few people were mentioning rainbow attacks. What exactly is a rainbow attack and what are the best methods to prevent it?
Anyone know why it is called rainbow table? Just remembered we have learned there is an attack called "dictionary attack". Why it is not call dictionary?
let's just assume a simple non salted hash function, just a plain old $hash = md5($pass).
Premises:
the password hashing all takes place server side, and the hashes are stored in the database. The client has no way to see these.
a rainbow table…
I have downloaded Rainbow Tables from freerainbowtables.com. Its extension is .rti . I was wondering if there is a way to read this file as a text file or anyother file. I want to write a simple program to read this file and store its contents in a…
Suppose I have only the first 16 characters of a MD5 hash. If I use brute force attack or rainbow tables or any other method to retrieve the original password, how many compatible candidates have I to expect? 1? (I do not think) 10, 100, 1000,…
I am currently working on a parallel computing project where i am trying to crack passwords using rainbow tables.
The first step that i have thought of is to implement a very small version of it that cracks password of lengths 5 or 6 (only numeric…
I am implementing an assignment where I'm given 1000 SHA1 digests and their corresponding passwords (each 24bit or 6Hex digits long). I have to build a rainbow table <2MB on disk and in Java, I see that having chain lengths > 192 makes the search…
I recently obtained the l0pht-CD for windows and tried it out on my PC and It WORKS!!

I have some issues with an assignment have been given. The gist is that I have to do a rainbow attack on a "car fop".
With a generator table, the RainbowAttack.py script the following:
The key broadcasts to car (in this case the adversary)

My bank limits my password to 14 characters and I suspect they're encrypting with MD5 or an SHA hash, unsalted.
Are there rainbow tables that contain every possible hash up to 14 characters?
