Hi folks,
I have no idea how to convert salted MD5's back to normal MD5's so I can decode them.
If anyone can convert them back to normal MD5's it would be appreciated.

Your help is kindly appreciated. |
If you dont know what a salted hash is, well, it's much simpler than it sounds. You have a common string that you append to each password before you hash it.
For example, if the password you want to encrypt is "toxic", and your salt string is "foo", then you simply create a hash of "toxicfoo". Keep in mind that you must use the same salt string across your application, so you are able to validate the hash later. When you need to validate the hash, for example when a user logs in, simply add "foo" to the end of whatever he/she submits.
$password = "toxic";
$salt = "foo";
$hash = md5($password.$salt);
If is that the methodology used for the above hashes then all you have to do is to add the salted value at the end of every word in your wordlist .. pray and hope that the word is in your list.. but base on that methodology .. its very simple to change and modify it as you want ... for example ..
$password = "toxic";
$salt = "foo";
$hash = md5(md5($salt).md5($password));
so .. you dont only need the salted value .. you also need the method ..
..now.. taking the first value ae9f01362090ebe44fc534334dae7232 with Salt: EYN ... you will have to make a wordlist .. like
aEYN
bEYN
cEYN
.... .... .. ..
and so on ...
and try to brute force it ..
but as i mentioned on a different post .. salted md5 hashes .. are not always as secure as they look .. because of the collitions .. so .. arithmeticaly you may come up with a different plain text that leeds to the same salted hash ..
md5 hash method was developed mostly to avoid colllitions .. now with salted hashes .. Its like entering a vicious circle ...

vbulletin uses the following method:
$hash = md5(md5($pass).$salt);
i would also like to ask for some help... i have a full DB backed up on my HDD and i would like to crack few passes... is there a brute-force tool where you can chose the algorythm to calculate hashes?
thanks a lot in advance  |

There is one tool, able to various salted hashes cracking:
http://www.insidepro.com/eng/passwordspro.shtml
| Code: |
Hashes passwords recovery
The tool is designated to recover passwords for the following types of hashes:
MySQL
MySQL5
MD4
MD4 (Base64)
MD5
MD5 (Base64)
MD5 (Unix)
MD5 (APR)
SHA-1
SHA-1 (Base64)
as well as for hashes used by different PHP-programs:
md5(md5($pass))
md5(md5($pass).$salt)
md5(md5($salt).md5($pass))
|
It costs $40 though  |
