I was thinking, maybe someone has already done this or had this idea before me but even though...

Would it be possible to make a program that makes passwords and then makes them to md5 hashes ? and saves them towards some kind of file for database later on.

I mean i haven seen alot of sites that got hashdatabases and so on.. but isnt there a program that can make all this passwords with hashes and then save them directly to a file.

Just an idea ... maybe its stupid but anyway nows its in the air

this is the basic concept for rainbow tables. except you don't save each and every word with its hash but you optimize those tables to reduce the (enormous) size via mathematical algorithms and stuff.

for example the project at http://www.freerainbowtables.com/ has this goal to create the most extensive rainbow tables there are. go there to read more about their techniques.

of course they are useless against hashed passwords, but you can't have everything Smile

zigns - seems that you don't imagine the amount if possible passwords. Read some cryptography books and after that it's clear, why there are rainbow tables and why people still use wordlists - it's because keyspace of strong passwords is way out of current computer hardware possibilities Smile
