create md5 hash (salt+value)

Question

How could I create the following PHP code in C# ?

Php code:

<?php
    $salt = "salt";
    $value = "hello";
    $password_hashed = md5($salt.$value);
?>

I would appreciate any kind of help. Been testing the following:

But it would only return a wrong string.

        var salt = System.Text.Encoding.UTF8.GetBytes("salt");
        var value = System.Text.Encoding.UTF8.GetBytes("hello");

        var hmacMD5 = new HMACMD5(salt);
        var saltedHash = hmacMD5.ComputeHash(value);

        string hex = BitConverter.ToString(saltedHash);
        MessageBox.Show(hex.Replace("-", ""));

The response should look like: 06decc8b095724f80103712c235586be

What do you mean by "couldn't be used"? The web is full of examples about how to convert a byte array into an hex String — SJuan76, Dec 19 '16 at 01:10

Hope this will help, it's some modification from given link

class Program {
    static void Main(string[] args) {
        var provider = MD5.Create();
        string salt = "S0m3R@nd0mSalt";
        string password = "SecretPassword";
        byte[] bytes = provider.ComputeHash(Encoding.ASCII.GetBytes(salt + password));
        string computedHash = BitConverter.ToString(bytes);

        Console.WriteLine(computedHash.Replace("-", ""));
    }
}

@d4ne please don't use MD5 for security. It's completely broken – Camilo Terevinto Dec 19 '16 at 01:26
It's not meant for a password, its meant to create a ticket id – d4ne Dec 19 '16 at 01:27
@CamiloTerevinto: do you suggest SHA512 and with some loops to prevent brute force atk? – Hadi Susanto Dec 19 '16 at 01:28
I'm using this the following way: its meant to create a ticket id for example url.com/viewticket.php?id=md5(salt+value) – d4ne Dec 19 '16 at 01:29

if you want a ticket ID, just use Guid.NewGuid – Joe Phillips Dec 19 '16 at 01:32
@d4ne Then that's fine. But don't use any real password in the code. You could maybe even get faster alternatives like Guid's – Camilo Terevinto Dec 19 '16 at 01:32
