![]() ![]() They would likely only work with a predefined “random character” set and password strings below 12 characters as the size of the table would be prohibitive to even state-level hackers otherwise. There is the talk of salted rainbow tables existing, but these would be so large as to be difficult to use in practice. They require serious computing power to run and a table becomes useless if the hash it’s trying to find has been “salted” by the addition of random characters to its password ahead of hashing the algorithm. However, rainbow tables are huge, unwieldy things. Rainbow tables are attractive as it reduces the time needed to crack a password hash to simply just looking something up in a list. This table contains hashes of all possible password combinations for any given hashing algorithm. Weak Passwords Hackers can easily hack Facebook accounts by guessing or performing a brute force attack if the password is easy and commonly used such as a. In the most straightforward way possible, you can boil a rainbow table down into a list of pre-computed hashes – the numerical value used when encrypting a password. Rainbow tables aren’t as colorful as their name may imply but, for a hacker, your password could well be at the end of it.
