CRACK's experienced handwriting 8 --- Crack flow wind wedding image design system 2002 version of the serial number encryption
/ / -------------------------------------------------------------------------------------------- --------
The encryption algorithm of this program is particularly long.
Many of these functions only generate some constants in the EXE resource string into the EXE (may be related to the software's No. Batch number)
And for a single copy, its encryption algorithm is extremely simple!

1. Let's talk about how to dynamically remove the correct number from the memory.
a. Running software, appears in the input serial number window, CTL_D out of Softice, under the BPX getWindowText Do "BD0"
b. Enter a false serial number LF2002123SM, determine. Blocked by Softice, f12 once, the command G 349C
Stop here:
CSEG119: 348E Add Ax, Word PTR [BP VAR_TEMP1]
CSEG119: 3491 ADC DX, WORD PTR [BP VAR_TEMP1 2]
CSEG119: 3494 Add Ax, Word PTR [BP VAR_SYSTEMID]; Plus System ID Number
CSEG119: 3497 ADC DX, WORD PTR [BP VAR_SYSTEMID 2]; 0
CSEG119: 349A POP SI
CSEG119: 349B LEAVE
CSEG119: 349C RETF 8 <------------ Stop here DX: AX memory value, such as DX = 0001; AX = 0236. At this time, the value of DX: AX will see its decimal value 66102 c. Ok, let's write down this number, we have already gone! Now I can know the correct serial number is the format of all the serial numbers of the LF200266102SM, that is, LF2002XXXXSM, where xxxx is the number of decimers we found above: Please write down the sequence number dialog box before registering the correct serial number. The system ID number given is useful! 2. The next time, how is it more convenient to get the serial number we have got a serial number, and there is a system ID number LF2002xxxxxsm XXXX minus system ID number, we will get a new number, I am 18176. This new number has true value. With this number, we can get a new serial number according to the new system ID (each installed) is available. For example, using the system ID plus this number 18176, get the digital xxxx, the correct serial number is LM2002XXXXSM is not easy.
