Subject: Re: PHP Script to Hash Plain-text input to LM/NTLM
Small correction, all 14+ passes were null'd, so here is the corrected
version so that NTLM can still be hashed:
(sorry to spam, it was bugging me when I realized it after I sent)
<?php
//Cobbled together by RichRumble, Xinn.org
//Code used is from:
//http://www.php.net/manual/en/ref.hash.php#84587
//http://www.php.net/manual/en/ref.hash.php#94990
header("Content-Type: text/plain");
function NTLMHash($Input) {
$Input=iconv('UTF-8','UTF-16LE',$Input);
//$MD4Hash=bin2hex(mhash(MHASH_MD4,$Input));
$MD4Hash=hash('md4',$Input);
$NTLMHash=strtoupper($MD4Hash);
// Return the result
return($NTLMHash);
};
function LMhash($Input)
{
$Input = strtoupper(substr($Input,0,14));
$p1 = LMhash_DESencrypt(substr($Input, 0, 7));
$p2 = LMhash_DESencrypt(substr($Input, 7, 7));
return strtoupper($p1.$p2);
};
function LMhash_DESencrypt($Input)
{
$key = array();
$tmp = array();
$len = strlen($Input);
for ($i=0; $i<7; ++$i)
$tmp[] = $i < $len ? ord($Input[$i]) : 0;
$key[] = $tmp[0] & 254;
$key[] = ($tmp[0] << 7) | ($tmp[1] >> 1);
$key[] = ($tmp[1] << 6) | ($tmp[2] >> 2);
$key[] = ($tmp[2] << 5) | ($tmp[3] >> 3);
$key[] = ($tmp[3] << 4) | ($tmp[4] >> 4);
$key[] = ($tmp[4] << 3) | ($tmp[5] >> 5);
$key[] = ($tmp[5] << 2) | ($tmp[6] >> 6);
$key[] = $tmp[6] << 1;
$is = mcrypt_get_iv_size(MCRYPT_DES, MCRYPT_MODE_ECB);
$iv = mcrypt_create_iv($is, MCRYPT_RAND);
$key0 = "";
foreach ($key as $k)
$key0 .= chr($k);
//Each keys is used to DES-encrypt the constant ASCII string "KGS!@#$%"
//(resulting in two 8-byte ciphertext values).
$LMHash = mcrypt_encrypt(MCRYPT_DES, $key0, "KGS!@#$%", MCRYPT_MODE_ECB, $iv);
return bin2hex($LMHash);
};
$array = file("pt-input.txt");
$a = 0;

$line = trim($line);
if (strlen($line) > 14) {
$NTLMout = NTLMHash($line);
$LMout = LMHash("");
} else {
$NTLMout = NTLMHash($line);
$LMout = LMHash($line);
};
print "user-" . $a++ . ":0:" . $LMout . ":" . $NTLMout . ":::" . "\n";
};
