Hi Luigi. Great and rare to find project in a net.

I have seen your ServerList Browser source, but i need vice versa thing to do. I need to encrypt ip, port, and other data if needed, by enctypex and send it to client. Is it possible with your existing work, or i got to reverse gslist decode algorithm?

sure it's already possible :)
in enctypex_decoder.c the last function is just enctypex_quick_encrypt.
for additional info take a look at the following thread:
master-server-emulation-with-enctypex-t552.html

It is just what i was looking, both the thread, and the code. Big Thx.

Hi Luigi. Having problems with <enctypextest> app. I give filename, gamekey, and validation key args, app is showing me original, decoded dump and then crashes. As i looked source, there must be encoded, and decrypted again. Having Win7 OS, can it be it? Was trying to rewrite encryption to another language, but have problems too, cause as i sniffed data from GSpy, encrypted data must start with bytes 0x(from e0 to fd) , 0x00 , 0x00, but your code encrypting whole data array, with header, cause

Code:

int enctypex_func6e(unsigned char *encxkey, unsigned char *data, int len) {
    int     i;

    for(i = 0; i < len; i++) {
        data[i] = enctypex_func7e(encxkey, data[i]);
       }

ecrypt all elements from 0 to len.

can you send me the file you used and both the gamekey and validate values via pm?
maybe it's a problem caused by the file you passed to the tool that contains other data instead of only the encrypted block (don't worry it's normal, the tool is simple so doesn't scan the file for the encrypted data automatically)

eh eh eh the tool doesn't work in that way.

first because the file it wants is the encrypted content because it performs the following operations on it:
- decryption
- re-encryption

then you need to pass it the binary formatted content, not the plain-text one.
just like the data you see when you when you use gslist -o 6 but without the initial header (eb 00 00 00) because it's automatically added by enctypex_quick_encrypt

the simplest format for containing the various IP:port is the following:

Code:

bytes
4       client's IP, set it to 0
2       most used port, set it to 0
1       number of static parameters, set it to 0
1       number of static values, set it to 0

for each server IP:port:
1       type, set it to 0x11
4       IP
2       port

final:
1       set it to 0
4       set it to 0xffffffff
