You can download/buy gigabytes of rainbow tables somewhere. You couldР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ve used MDCrack () or any of the various MD5 hash cracking sites, or RainbowCrack using rainbow tables (as you mentioned). I doubt, however, that they envisaged this use though. Google is doing what it does best - storing large databases and searching them. MD5 is quite fast, and while itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s unlikely to be the best option in all cases, it is an easy solution which works pretty well.Р В РІР‚СњР вЂ™Р’В«ecause of this technique, Google is acting as a hash pre-image finder, and more importantly finding hashes of things that people have hashed before. If there are too many entries to store in a single directory, by creating directories for each prefix, there will be an even distribution of files. This avoids the need to escape any potentially dangerous user input and is very resistant to accidental collisions. When I needed to store a file, indexed by a key, a simple option is to make the filename the keyР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s MD5 hash.

This makes a lot of sense - IР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ve even written code which does the same. In both the webpages, the target hash was in a URL. And indeed, the MD5 hash of Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўAnthonyР В Р вЂ Р В РІР‚С™Р РЋРЎС™ was the database entry for the attacker. I found, for example, a genealogy page listing people with the surname Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўAnthonyР В Р вЂ Р В РІР‚С™Р РЋРЎС™, and an advert for a house, signing off Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўPlease Call for showing. I could also improve efficiency with a rainbow table, but this needs a large database which I didnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t have. o Р В Р вЂ Р Р†Р вЂљР’В Р Р†Р вЂљРІвЂћСћ 0, a Р В Р вЂ Р Р†Р вЂљР’В Р Р†Р вЂљРІвЂћСћ 4) but that would have taken more time than I wanted to spend.

I could have found or written a better password cracker, which varies the case of letters, and does common substitutions (e.g. Then, I switched to a Russian dictionary (because the comments in the shell code installed were in Russian) but that didnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t work either. So, I wrote a trivial Python script which hashed all dictionary words, but that didnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t find the target (I also tried adding numbers to the end). Instead, someone would have to try out all possible inputs until the correct output is discovered. As with any respectable hash function, it is believed to be computationally infeasible to discover the input of MD5 from an output.

WordPress stores raw MD5 hashes in the user database (despite my recommendation to use salting).

I quickly disabled the account, but while doing forensics, I thought it would be interesting to find out the account password.

Support rainbow table in raw file format (.rt) and compact file format (.One of the steps used by the attacker who compromised Light Blue Touchpaper a few weeks ago was to create an account (which he promoted to administrator more on that in a future post).

Support rainbow table of any hash algorithm.

Full time-memory tradeoff tool suites, including rainbow table generation, sort, conversion and lookup.

Some organizations have made RainbowCrackР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s rainbow tables available free over the internet. With this type of hash cracking, all intermediate computation results are discarded. If all possible plaintexts are tested and no match is found, the plaintext is not found. Once a match is found, the plaintext is found.

It differs from brute force hash crackers.Р В РІР‚СњР В РІР‚С› brute force hash cracker generate all possible plaintexts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked.

RainbowCrack uses time-memory tradeoff algorithm to crack hashes. RainbowCrack was developed by Zhu Shuanglei, and implements an improved time-memory trade-off cryptonalysis attack which originated in Philippe OechslinР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s Ophcrack. RainbowCrack differs from Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўconventionalР В Р вЂ Р В РІР‚С™Р РЋРЎС™ 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. RainbowCrack is a computer program which generates rainbow tables to be used in password cracking.
