Encryption Question

[biokr78]

I am looking at the code:

 

$passwd="newton";

$strMD5=md5($passwd);

$arrMD5Chars = str_split($strMD5, 1);

foreach ($arrMD5Chars as $value)

{

    $intTotal += '0x0'.$value;

}

 

and trying to figure out what the "$intTotal += '0x0'.$value" part does. Any suggestions?

It is inserting '0x0' between each character for the encrypted password..

 

example:

 

if encrypted password : Xakf12dszO

 

$intTotal = X0x0a0x0k0x0f0x010x020x0d0x0s0x0z0x0O

 

dont understand why it is done so though..may be a checksum or something like that not sure.
