The packet is from the packetlooger, I just copy paste it.

Then generate it?

But why it doesn't work, it is supossed to work no? It's the same packet.

Note that the right packet depends on: client version, client exe files, account data and your hardware (or pc)

the GUID dont care so much for me i generate it for each login new and it works. But i think the 0x0B can be maybe the problem.

I found the error. Yey

There is a lot of confusion here.

You should use a std::string to store the packet and encrypt/decrypt it. Finally you should cast it to const char* using .c_str() method and pass it to send() function with .length(). It does not care \0 since send() function is using the length you pass it as parameter.

NostaleString is an alternative to AnsiString for packet injection. It is not related to clientless.

When you have decrypted bytes you should never use a string due to the null byte.
Use a std::vector.
And no, C/C++ terminates strings on the first found \0 byte. You cannot change that.

What you said is a bullshit.
In fact, std::string is not caring \0 at all.

It is not bullshit since it's about printing a encrypted text packet which contains \0. He might use a vector from the beginning which makes it easier than with a std::string.

Illuminate me. How is std::vector easier than std::string? The std::vector<char> .data() method returns a const char* which is exactly the same as std::string .c_str(). A std::string is not using \0 or any delimiter at all. You can operate on std::string the same way you operate on std::vector with the benefit of not having to convert from const char* to std::vector to convert it back again to const char* or std::string. You also have access to very useful methods which you may need. What you are saying is senseless and you should stop spreading disinformation out there.

Yes, you should. No. Print the string directly.

int main()

	// print plaintext packet
	
	std::cout << packet << std::endl;
	
	// encrypt
	
	for (std::size_t i = 0; i < packet.length(); i++)
	{

		packet[i] += 0x0F;
	}

Someone could help me to compile curl library for windows? I want to use it but I don't know how to compile this **** library.

You can find compiled binaries too

Do you know why I get this error? Did I linked bad the libraries?

#include <iostream>
#include <string>
#include "curl.h"

static size_t WriteCallback(void* contents, size_t size, size_t nmemb, void* userp)
{
	((std::string*)userp)->append((char*)contents, size * nmemb);
	return size * nmemb;
}

int main(void)
{
	CURL* curl;
	CURLcode res;
	std::string readBuffer;

	curl = curl_easy_init();
	if (curl) {
		curl_easy_setopt(curl, CURLOPT_URL, "http://www.google.com");
		curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
		curl_easy_setopt(curl, CURLOPT_WRITEDATA, &readBuffer);
		res = curl_easy_perform(curl);
		curl_easy_cleanup(curl);

		std::cout << readBuffer << std::endl;
	}
	return 0;
}

I thought you wanted help for C++ code.
Why I see you only posting C code in 2 pages?
It is horrible to read.

You probably want to use Boost.Beast instead of curl:

To solve your error you have to link curl .lib(s)

My idea is to do it in C++ but I took this example code for a random page.

I see. The hardest part of learning programming is that most of code you can find online is done wrong. Feel free contacting me in private for any question. I will be glad to help you.
