Bug description: Crypt - Different Hashes on Windows and Linux on wrong Salt
size
Description:
------------
The behave of Crypt function on Windows and Linux boxes are different.
In the sample function we create a Salt with length of 12 characters.
First, the Salt size is incorrect, if i remove one character the Salt, the
result will be correct.
But with the wrong Salt size the behavior are different:
On Windows - The output is incorrect, as it shows the whole Salt without
the terminator $...
On Linux - PHP strips one character of Salt into it's correct expected
size, outputing correctly with the terminator $...
Reproduce code:
---------------
md5crypt("test");
function md5crypt($password)
{
$base64_alphabet='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
.'abcdefghijklmnopqrstuvwxyz0123456789+/';
$salt='$1$';
for($i=0; $i<9; $i++)
{
$salt.=$base64_alphabet[rand(0,63)];
}
$salt.='$';
echo "<pre>";
echo "Salt: ".$salt."<br />\r\n";
echo "Output: ".crypt($password,$salt);
echo "</pre>";
}
Expected result:
----------------
Salt: $1$f+uslYF01$
Output: $1$f+uslYF0$orVloNmKSLvOeswusE0bY.
//Linux
Actual result:
--------------
Salt: $1$XcPmtBmRG$
Output: $1$XcPmtBmRGuM82Sm1HMy0I0lX0P3nAd0
//Windows
