Hash
For thoes of you who're looking to generate an NTLM hash (not an LM hash), I found out it's quite simple..
It uses the basic MD4 function, but the password needs to be in Unicode Little Endian encode first (this canbe achieved by the iconv function).
This can be done easily by using the following code:
<?php
function NTLMHash($Input) {
// Convert the password from UTF8 to UTF16 (little endian)
$Input=iconv('UTF-8','UTF-16LE',$Input);
// Encrypt it with the MD4 hash
$MD4Hash=bin2hex(mhash(MHASH_MD4,$Input));
// You could use this instead, but mhash works on PHP 4 and 5 or above
// The hash function only works on 5 or above
//$MD4Hash=hash('md4',$Input);
// Make it uppercase, not necessary, but it's common to do so with NTLM hashes
$NTLMHash=strtoupper($MD4Hash);
// Return the result
return($NTLMHash);
}
?>
To produce an LM hash requires a fully-written script containing the algorithm used to make it.
Enjoy,

martin: That's because some distributions, such as FreeBSD's ports and Debian's apt split PHP's modules into different packages.

I tried to use Hash() function on my PHP 5.2.3 (FreeBSD 6.2) but there was no Hash() function. (it should be available by default from version 5.1.2)
Hash() function was working after installing "security/pecl-hash" port.

Some tests with mhash and hash revealed on my machine that hash needs more than twice as long to create a hash than mhash. The average of one million cylces of Haval128, Haval256, Gost, CRC32, MD5, SHA1 and SHA256 was 450ms for mhash and 1150ms for hash.
