How does someone attack a WPA/WPA2 wireless network? I have read on the two main approaches: dictionary and rainbow tables. How do you use rainbow tables in conjunction with your tool of choice? I ...
I've read about rainbow tables (which I've confused with hash tables at first). I understand that it uses a reduce function R(x) and by saving start value P(plaintext) and ending hashed value H I can ...
With large computing power (like what you can get in the Amazon cloud for example) you can generate huge rainbow tables for passwords. There also seems to be some large rainbow tables reachable that ...
I was wondering about md5 encryption. It is good, and I agree that it is unbreakable. But this is why we have rainbow tables. What if bunch of people gather together and start brute forcing and ...
I want to compute the possible combinations of a password consists of 8 digits of: alphabetical letters (26), numbers (0-9), symbols and punctuations. In order to compute this, I have to know the ...
I know there are many discussions on salted hashes, and I understand that the purpose is to make it impossible to build a rainbow table of all possible hashes (generally up to 7 characters). My ...
Surely we could just make it so a rainbow table says for each beginning of chain do 10k iterations, and then we wouldn't have to store both values? Or does by doing it this way stop collisions?
Given, we want to crack a password. With Time Memory Trade-Off Attacks one tries to find the right balance between time to compute hashes for all possible passwords. And the used memory to store all ...
Where can I find one? Is there a pot of gold at the end? How do I protect against them? From the Area51 proposal This question was IT Security Question of the Week. Read the Sep 09, 2011 blog ...
