Maybe your site have a redirect from http to https or something. In that case, use https link in the patcher.

Give me your link in DM and I'll have a look.

Edit: @GoldCash Your patchlist.txt is wrong, you have to remove the D:/Client/ from every line.

Also when I first opened the link, it said website unavailable for like 5 second then Chrome refreshed. I'm sure there are some protection / pre-filter enabled in your webserver. I never used LiteSpeed so can't tell more.

Are u using a free storage just for test? Cuz this will not work  I tried with a lot of free cloud storage, but nothing worked. I bought a cloud storage for 1year (cost me 12€) and it worked instantly.

Sry for my bad english.

Hi, try to change crc hash to md5, it helped me.

In Common.cs

Add this in begging of the file:

using System.Security.Cryptography;

and after:

        public static string GetHash(string Name)
        {
            if (Name == string.Empty)
                return string.Empty;

            CRC crc = new CRC();

            string Hash = string.Empty;

            using (FileStream fileStream = File.Open(Name, FileMode.Open))
            {
                foreach (byte b in crc.ComputeHash(fileStream))
                {
                    Hash += b.ToString("x2").ToLower();
                }
            }

            return Hash;
        }

add:

        public static string CalculateMD5Hash(string Name)
        {
            if (Name == string.Empty)
                return null;

            MD5 md5 = System.Security.Cryptography.MD5.Create();

            string Hash = string.Empty;

            try
            {
                using (FileStream fileStream = File.Open(Name, FileMode.Open, FileAccess.Read, FileShare.Read))
                {
                    foreach (byte b in md5.ComputeHash(fileStream))
                    {
                        Hash += b.ToString("x2").ToLower();
                    }
                }
            }
            catch
            {
                MessageBox.Show("Can't open: " + Name);
            }

            return Hash;
        }

In FileChecker.cs find:

if (!File.Exists(file.Name) || Common.GetHash(file.Name) != file.Hash)

and replace with:

if (!File.Exists(file.Name) || Common.CalculateMD5Hash(file.Name) != file.Hash)

After these changes you'll have MD5 Patcher

PS: Atm I'm experiencing some problems with progress bar, will add solution if I'll find it.

 

 

 

 

Also I'd like to share php script which generate patchlist.txt (probably will be useful for someone):

  Hide contents

 

<?php
/*
Usage: Upload this file to the web-server, in folder with patchlist.txt and open it in browser.
Note: I recommend to protect this file from public usage with password (put file in folder, change output file and directory path and and use .htaccess)
*/
function list_directory($dir) {
	$file_list = array();
	$stack[] = $dir;

	while ($stack) {
		$current_dir = array_pop($stack);
		if ($dh = opendir($current_dir)) {
			while (($file = readdir($dh)) !== false) {
				if ($file !== '.' AND $file !== '..') {
					$current_file = "{$current_dir}/{$file}";
					$report = array();
					if (is_file($current_file)) {
						$file_list[] = "{$current_dir}/{$file}";
					} elseif (is_dir($current_file)) {
						$stack[] = $current_file;
						$file_list[] = "{$current_dir}/{$file}/";
					}
				}
			}
		}
	}

	return $file_list;
}

$files = list_directory('.'); // Path to directory with files
sort($files, SORT_NATURAL | SORT_FLAG_CASE);
$line = "";
foreach($files as $file)
{
	$hash = hash_file( 'crc32b', $file );
	$size = filesize($file);

	if($hash == "00000000" || preg_match("/patchlist/", $file))
		continue;

	$file_n = preg_replace("/^../","",$file);
	echo $file_n . " " . $hash . " " . $size . "<br>";
	$line .= $file_n . " " . $hash . " " . $size . "\r\n";
}

$handle = fopen("patchlist.txt", "w+"); // Path to output file
fwrite($handle, $line);
fclose($handle);
?>

 

Best Regards

Hi, I've done as indicated.
After creating the patch list and using the patcher, everything downloads perfectly.

If I close the patcher and open it up again, somehow it checks for the files and then redownloads all the files...

anyone knows how to fix this?

the patcher is working but the problem is, that he downloading everytime all files, not only the changed files. 

[Jimmermania 36]

@ TMP4 you had some temporary keys. What are the passwords? i cannot create new cause your design is fixed with this key.

This is obviously just a false positive caused by how retarded heuristic detection is nowadays in antivurses.

What you're gonna do to fix this is switch target .NET framework version and simply recompile. Should do the trick.

[dexolus 82]

Hey thanks for asnwering.. I tried every possible framework but still getting loads of shit around 22 Security vendors on VirusTotal sometimes less (probably depends on framework or dunno howit works) Do you have any other fix in mind? Thanks..

Up! After creating a design and compiling multiple times, I've started to get microsoft antivirus notifications. I believe I will have issues with virus total too. Does anyone have figured it out a solution?

I don't think there is any option to fix this. In the past I was using application security certificate (it's paid option). It helps a lot.

You can just report your binary to AV companies for whitelisting. No need for EV certs

Dont you need to do this every time you compile binary?

[Yazoo 2]

I took the time to make a patcher using the SHA-256 hash, which works perfectly fine, even though the one from Sanchez doesn't use this hash.
To download my files, I only use System.Net.Http in C# with HttpClient.
My patcher is compiled in .NET 6, and I integrate my DLL, which is also compiled, directly into my patcher.exe.
I just ran a VirusTotal scan on my old patcher, and it shows 0/73 detections. However, the one I'm currently modifying sometimes generates 1/73 detections. I'll attach an image of the VirusTotal results for reference.

Yes since the hash changes but well written patcher doesnt really need recompilation. You just compile it once and leave it as is. Any dynamic content such as image sliders or patch list can be pulled dynamically from your remote server

[jking 682]

Ye ye, I thought we were talking about client binary.
