Right now, MD5s > 8 characters are impossible to brute force. Brute forcing 9 characters alphanumeric takes a year and 10 characters alphanumeric takes 25 years. And rainbow tables can only do up to 8 characters because of the disk space. Most passwords are 9-10 characters so if there was an online cracker that could do up to 10 character passwords, it could make MD5s very insecure.
What if we made an online cracker that runs rainbow tables up to 8 characters and then splits up the keyspace and sends it to 5000 volunteers' computers. By splitting up the keyspace over 5000 computers, we could test a 9-10 character password in a day instead of 26 years. |

well 9 characters alpha is possible but 9 characters alphanumeric takes over a year... and 10 characters alphanumeric takes over 25 years... 11 characters alphanumeric takes over 800 years. milw0rm's cracker only goes up to 7 characters, and they have cracked less than half of their hashes.
But my point is that if we make a project that splits up the keyspace between volunteers' computers and get [the number of years the keyspace takes] * 365 volunteers, we could try the keyspace in a day, and potentially crack keyspaces like alphanumeric 9-11, which would totally make MD5 insecure. |

9-9 loweralpha-numeric would take 25 years to make. If you get 5000 volunteers it will take only 2,94 day per person. But you will never get that mutch volunteers so forget it...  |

Rainbow tables as the answer to 'cracking' passwords quickly, and how to imlement this, is always fun for me to think about. I'm more of a hardware engineer than software, and have always thought a fun project would be a hardware based rainbow table generator/cracker. I'm curious to know how well hardware could do the job. I'd bet that a rainbow table custom processor could be 1000x as fast. Would be a really fun project.. if only I had more time. |
