ACL file format

[prologos]

I'll try to speak only important part in understanding the structure of the file.
acl files, 188 bytes is assigned to each character that total 940 bytes.
Among the components of 188 bytes, the important part is the following.




When the server encrypts/decrypts the acl files are working off by 4 bytes.
Encryption/Decryption key code is as follows.

CSimpleCrypt::CSimpleCrypt()
{
	m_ConstKey1 = 2366183;
	m_ConstKey2 = 1432754;
	m_DynamicKey = 79984829;
}

CSimpleCrypt::~CSimpleCrypt()
{
}

void CSimpleCrypt::Encrypt32bit(const char * pSrc, char * pDest)
{
	int DynamicKey = m_DynamicKey;

	for (int i = 0 ; i < 4 ; i++)
	{
		pDest[i] = (char)((BYTE)(pSrc[i]) ^ (DynamicKey >> 8));
		DynamicKey = ((BYTE)(pDest[i]) + DynamicKey) * m_ConstKey1 + m_ConstKey2;
	}
}

void CSimpleCrypt::Decrypt32bit(const char * pSrc, char * pDest)
{
	int DynamicKey = m_DynamicKey;

	for (int i = 0 ; i < 4 ; i++)
	{
		pDest[i] = (char)((BYTE)(pSrc[i]) ^ (DynamicKey >> 8));
		DynamicKey = ((BYTE)(pSrc[i]) + DynamicKey) * m_ConstKey1 + m_ConstKey2;
	}
}

Example:
acl original | Encryption(packet)
---------------------------
00 00 00 00 <-> 78 9D 01 F5
00 01 00 00 <-> 78 9C E6 49
A5 00 00 00 <-> DD 3A F2 79
00 FF 00 00 <-> 78 62 CE 12
00 00 00 00 00 01 00 00 A5 00 00 00 <-> 78 9D 01 F5 78 9C E6 49 DD 3A F2 79



Tips on 562 Client:
Algorithm, encryption/decryption of the packet is also a 562 Client.
The only changes are the part that represents the type of character.

Initial value
219 Client | 562 Client
-------------------------
00 FF 00 00 | 00 00 FF 00


If there are any characters
219 Client | 562 Client
-------------------------
00 CL TW 00 | 00 01 CL TW

CL: Type of character (When you delete a character, FF)
TW: Hometown


How to solve this problem (choose one)
1. Debug and fix the AS.
2. Use to change the acl packet in 562 ZA.

2nd option is easy...
coz it will hard to debug account server... i think soo

but how to use this code...??
i am not getting it???
in C++ and make .dll from it???

 

[Devil Warrior]

can u tell me how to do Encryption/Decryption???
by application??
like i have got that application
what is the use of this Encryption/Decryption key code???
how to use that???

 

[prologos]

This is not a perfect code.
It is shown that the encryption/decryption is done in formula or just a few.

Does not have an application for Encryption/Decryption.
It is by using the formula above, you will be taken care of.

i am asking that in which application i have to use this code...
i know its not correct code... but tell me that which application run this code..???
like (C#,C++,Java script) in which???
and tell me the process of it ???

Above code is in C++. I think you should make a DLL and call its function in your ZA.

 

[chrissdegrece]

The released DLL can be used fine with the released VB ZA. Call the DLL functions from VB, modify packets and it's done.

in vb 6 i have to add that asdecr.dll as related document??
coz asdecr.dll file is made in c++ 2010

:?:
when i am adding asdecr.dll in vb 6 as reference

tell me how many references have to add???

 

[chrissdegrece]

To view the content, you need to sign in or register

 

[Devil Warrior]

chrissdegrece thxx for help

but have question

have to register that asdecr.dll??
by regsvr32.exe???

 

[Devil Warrior]

Private Declare Function decrypt_acl Lib "asdecr.dll" (ByVal acldata As String, ByVal size As Long) As Long

is that correct??
and i replaced all timegettime to decrypt_acl

error coming @ here

can u tell which address should have to edit in account server to log character properly??

 

[xqtronline]

Devil Warrior you can make it

@ prologos
can u tell me how to fix acl in account server??
any address in hex??
