Feel free to flame if this isnt the right place 
Im a noob at this sort of thing, but ive gotten curious. I decided to try to crack one of my own passwords to see if i can do it. Well, after a few mins i thought i had my md5... much to my surprise, the md5 wasn't being decoded from any of the online applications i tried, and i simply could not produce a proper password from cain or passwordspro. Then I learned about salt... ><
is there any way to get around this salt? remove it from the equation, or wtvr is necessary, so I can properly decode this md5? If it is possible, i'd rather learn how to do it myself than have someone do it, so i wont post the md5 unless I have to. Thanks! |

salting is an extra feuture added to the actual method of hashing a password.
The result though of that method is a different MD5 value.. but more difficult to crack.
md5 output is a fix 32 character [A-f] [0_9] value
salted md5 has the same output.
but the method of hashing it :
if you need a method like this to make a simple hash
md5($value)
the salted is
md5(md5($value+$salt)
where $salt is a NON FIXED random value
as i mentioned above at both cases the result is a fixed value so you cannot distinguish whether a value is salted or not.
The best thing to do is to make a research on the php application how it stores the value to the database or when you post in the forum to crack a value for the people who are willing to help you you have to tell the php application that hash came from and the salted value.
Most of the times salted value is located at the same table that the password is.So with a small modification of the query you can come up with the salted value. |
