| A sql file with lots of usernames, md5s, etc. I am looking for a way to remove the md5s and organize them into a list. Any ideas? |

Write script for that - in perl, php or other language. Or write shell script.
It's simple string manipulation 
By the way i'm using special php CLI script, which takes raw copy-pasted text, extracts md5 hashes and then exports them to Cain cracker. Very useful, lot easier as copy-paste one-by-one |

Yes, I could, but I'm not very good at scripting. I was wondering if anyone had one, otherwise I guess I'll have to hit the books  |

Yes, first thing to do is to remove unneeded info and let only user data.
I can write needed php script within minutes, but i need source.
Can you use php scripts on you PC? And if you dont have privacy concerns, then upload packed file somewhere and gimme da link. And i will write script for md5 extracting.
... Tomorrow, becaue right now there is 5:43 AM where I live |

See, the thing is i kinda do have privacy concerns. The file basically looks like this all the way through:
','cc8cc5a0b0cd91564ea8b3514fa82d05',1165473474,-4,1165472573,1165472483,0,0,'0.00',4,'english','D M d, Y g:i a',2,0,1175641746,0,0,NULL,0,1,1,1,1,1,1,1,1,1,1,0,' |

OK, here is php CLI script I wrote today:
| Code: |
<?php
error_reporting(E_ALL);
//=======================================================
$infile = 'test.txt';
$outfile = 'out.txt';
//=======================================================
if(!is_file($infile))
{
die('Cannot open input file, exiting!');
}
$buff = file_get_contents($infile);
$buff = strtolower($buff);
$arr = array();
$cnt = preg_match_all('/\'[a-f0-9]{32}\'/',$buff, $arr);
echo "found $cnt hashes\n";
$arr2 = array();
for($i = 0; $i < $cnt; $i ++)
{
$arr2[] = str_replace('\'', '', $arr[0][$i]);
}
$arr = array_unique($arr2);
$arr2 = array();
foreach($arr as $hash)
{
if(preg_match('/^[a-f0-9]{32}$/',$hash))
{
$arr2[] = $hash;
}
}
sort($arr2);
$cnt2 = count($arr2);
echo "got $cnt2 unique hashes\n";
$out = implode("\n", $arr2);
$fh = fopen($outfile, 'wb');
fwrite($fh, $out);
fclose($fh);
die("--okok--");
?>
|
It is simple script and can't handle too big input files (> 20MB). And there can be some "noise", because hash extracting regex is as simple as possible. If someone writes better version - share it here |

waraxe i don't try your script but look nice.Install phpmyadmin on your PC.Import this dump in some db.After that simple sql query
example
Select concat(username,":",password) from users
Select concat(username,":",password,":",salt) from users |
