Question

I have a hashing method in C# that looks like:

MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();

byte[] raw_input  = Encoding.UTF32.GetBytes("hello");
byte[] raw_output = md5.ComputeHash(raw_input);

string output = "";
foreach (byte myByte in raw_output)
    output += myByte.ToString("X2");

return output;

How can I implement this in PHP? Doing the following produces a different hash digest…

$output = hash('md5', 'hello');

Answer 1

PHP

This PHP code will do:

<?php
$str = "admin";
$strUtf32 = mb_convert_encoding($str, "UTF-32LE");
echo md5($strUtf32);
?>

This code outputs “1e3fcd02b1547f847cb7fc3add4484a5”
