Hi, I am creating some aplications for HLDS... Ej: Ftpd Server, A Remote chat for every one.., etc...
Well. So I send all the information by sockets.
I create this easy way to pack the info and send it....

Well the simple question...
Is a better options??

PHP Code:

#define _CRT_SECURE_NO_WARNINGS

#include< stdio.h >
#include< stdlib.h >
#include< string.h >

#include "md5.h"

char *createPacket( const char *sender, const char *password, const char *msg );
void uncreatePacket( const char *packet, char *sender, char *md5password, char *msg );

int main()
{
    char *print = createPacket("ReymonARG", "micontraseña", "Hola este es un mensaje feliz..");

    for( size_t i = 0; i < strlen(print) ; i++ )
        printf("%c", print[i] );
    
    printf("\n\n");

    char user[32];
    char password[33];
    char msg[160];

    uncreatePacket(print, user, password, msg);

    printf("User: %s Pass: %s Msg: %s\n\n", user, password, msg);

    system("pause");
    return 0;
}

char *createPacket( const char *sender, const char *password, const char *msg )
{
    static char buffer[200]; // Max msg is 192. - md5 - stupids byts..
    char md5password[33];

    char *msgsend = new char[strlen(msg)];

    int klen = _snprintf(msgsend, 160, "%s", msg);
    msgsend[klen] = '\0';

    MD5 md5;
    md5.update((unsigned char *)password, strlen(password));
    md5.finalize();
    md5.hex_digest(md5password);

    int len = _snprintf(buffer, sizeof(buffer), "%c%c%c%c%c%c%s%c%c%s%c%c%s%c%c%s%c", -1,strlen(sender), -1, strlen(msgsend), -1, -1, sender, -1,-1, md5password, -1, -1, msgsend, -1);

    buffer[len] = '\0';
    return buffer;
}

void uncreatePacket( const char *packet, char *sender, char *md5password, char *msg )
{
    size_t senderlen = static_cast< int >( packet[1] );
    size_t msglen = static_cast< int >( packet[3] );

    for( size_t i = 0; i < senderlen; i++ )
    {
        sender[i] = packet[i+6];
    }
    sender[senderlen] = '\0';

    for( size_t i = 0; i < 33; i++ )
    {
        md5password[i] = packet[i+8+senderlen];
    }
    md5password[32] = '\0';

    for( size_t i = 0; i < msglen; i++ )
    {
        msg[i] = packet[i+42+senderlen];
    }
    msg[msglen] = '\0';

    return;
} 


md5.h is the same that is in amxmodx module....


Thanks...

You could look at RC4ing it, xoring it, using named pipes.. ect..

I must ask, what is this "Advanced Chat Program" exactly? heh.

Register users can conect to a listen port in the HLDS Server.
I Create a Little Program in VC++ that is like HLSW Rcon Chat, but for many users...

Thanks for you information..

heh, be careful with what information your compiling into your application.. Also, for future reference. I'd try making the client in C# and then the server in C++.

Why? C++ You can make it cross-platform compatible. And with C# it's much faster to create GUI's and do this in general.. Downfall is you can reverse it very easy. I'd obfuscate it if I were you but still can be reversed.

Is I am leaning C# with .NET...
If I have to make GUI Aplicattions that new many thinks I do with VB and a .dll in C++.

But now I start to read some books that I have from C#...

Again. Thanks
