[SA|CLEO] Lock your CLEO scripts

[indirivacua]

Many people been asking this (not really), so I made this tutorial of """how to encrypt/lock your cleo mods""", so nobody will can decompile it and read your super powerfull incredible piece of code!  (We going to call it SPIPOC since now).

 

This is a military grade encryption algorithm called XOR Crypt, and THE ONLY WAY to lock mods, nobody will can decrypt them, even if they read this topic will be impossible, you're safe

 

First, compile your SPIPOC in SB with 'Add extra info to SCM' flag unchecked.

For example, I made this SPIPOC:

 

{$CLEO}
{$NOSOURCE} // wait, waht?

0AD1: show_formatted_text_highpriority "This is %.4X opcode" time 2000 0x0AD1
0A93: end_custom_thread

 

Then with some hex editor open your compiled .cs file and copy all the content of the file:

D1 0A 0E 13 54 68 69 73 20 69 73 20 25 2E 34 58 20 6F 70 63 6F 64 65 05 D0 07 05 D1 0A 00 93 0A

 

Then use this algorithm to get your code F U L L Y encrypted:

#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#define XORKEY 7 // This is your encryption key

int main()
{
	uint8_t arr[] = {0xD1, 0x0A, 0x0E, 0x13, 0x54, 0x68, 0x69, 0x73, 0x20, 0x69, 0x73, 0x20, 0x25, 0x2E, 0x34, 0x58, 0x20, 0x6F, 0x70, 0x63, 0x6F, 0x64, 0x65, 0x05, 0xD0, 0x07, 0x05, 0xD1, 0x0A, 0x00, 0x93, 0x0A}; // Here should be the bytes of your code
	int length = sizeof(arr)/sizeof(uint8_t);
	printf("Lenght: %d\n", length);
	printf("Encrypted: \n");
	for (int i = 0; i < length; i++)
	{
		arr[i] = arr[i] ^ XORKEY;
		printf("%02X ",arr[i]);
	}
	return 0;
}

/* 	
	Output:
	
	Lenght: 32
	Encrypted:
	D6 0D 09 14 53 6F 6E 74 27 6E 74 27 22 29 33 5F 27 68 77 64 68 63 62 02 D7 00 02 D6 0D 07 94 0D
*/

 

Then copy the thing of the thing you got from the thing above and paste it into the hex dump:

{$CLEO}
{$NOSOURCE} // Again? :(

const
    key = 2@
end

key = 7 // Your key, big boy

0AC6: 0@ = label @label offset
for 3@ = 0x00 to 0x1F // 32-1 = 31, yei, we know maths, btw, 1F=31, and yeah, you can use decimal system, but c'mon, hex makes you look cool, right? right???
    0A8D: 1@ = read_memory 0@ size 1 virtual_protect 0
    0B12: 1@ = 1@ XOR key
    0A8C: write_memory 0@ size 1 value 1@ virtual_protect 0
    0@++
end

:label
hex
//HEEEEEERE
D6 0D 09 14 53 6F 6E 74 27 6E 74 27 22 29 33 5F 27 68 77 64 68 63 62 02 D7 00 02 D6 0D 07 94 0D
end

 

DONE, now you're a professional... hacker? whatever .

 

FAQ:

Are you being serious?

Nope

 

psst, read this boi

 

Everything has an history, right? I was sorting my bookmarks and one of them was a thread on this forum of "how to lock a cleo". I'm almost sure that I added it in 2015/2016, I was a non-open-source guy at that time, shame me. Three years ago I started university and most important, I started to learn why is better 'open sourcing'. So that's why I made this useful-unuseful funny tutorial

 

Andddd, in case you still don't get it, you can decrypt the script 'encrypted' by this method as the same way you encrypted it. With SB decompile it, copy all the content from the thread memory (hex...end) and paste into the array from the C code, you'll get the decrypted hex values, put them into a simply code like this one:

 

{$CLEO}

hex
//Here
end

And compile it without the 'Add extra info to SCM' flag checked. Voilà.

 

Btw, you need to understand you're not 'locking' anything, you're just confusing the decompiler. 

 

Maybe I'll update this topic with other ways to 'lock' (and unlock it, obviously) scripts in the future.

Huge grammatical errors. And some info about unlocking it.

Bro how can I decrypt any Cleo script that is locked
