please first look at the document passroaster.txt

shortly

Code:

password: "password" 
roastingstring: "tictoc"

returns: "0x04081007180c060d"

The following xor's are done:
p=01110000 t=01110100  xor = 00000100 hex = 04
a=01100001 i=01101001  xor = 00001000 hex = 08
s=01110011 c=01100011  xor = 00010000 hex = 10
s=01110011 t=01110100  xor = 00000111 hex = 07
w=01110111 o=01101111  xor = 00011000 hex = 18
o=01101111 c=01100011  xor = 00001100 hex = 0c
r=01110010 t=01110100  xor = 00000110 hex = 06
d=01100100 i=01101001  xor = 00001101 hex = 0d
So the method returns "0x04081007180c060d"

and in my little demostration app here i am just trying to roast the first char in password with the first char in roasting_array

i need some code there (commented in the code) to convert the number in ah to string and then i will send it to the static

Code:

  roast:
        invoke  GetDlgItemText,[hwnddlg],1002,password,password_max
        cmp     [password],0
        je      empty_password
        invoke  GetDlgItemText,[hwnddlg],1003,roasting_array,-1
        cmp     [roasting_array],0
        je      empty_roasting_array
        mov     ah,[password+0]
        mov     bh,[roasting_array+0]
        xor     ah,bh
        ;i need some code here to convert the number in ah to string and then i will send it to the static
        mov     [temp1+0],ah
        invoke  SetDlgItemText,[hwnddlg],1005,temp1
        jmp     processed

and also all suggestions about a loop for roasting all the password with all the roasting_array are welcome Smile

with corrections for the stupid things i have done
i am suffering from inexperience here Smile

if i can roast the password, i am going to create the very first login packet

Maybe this help...
Change szFileName and imgbase in loader.asm, compile both files, run loader.exe.

Sorry Im gonna have to jump off this project. I've dumped Windows completely and have moved over to Gentoo Linux distro ( www.gentoo.org ) for the past 2 weeks. Im loving gentoo and I plan to use flat assembler even on linux =). Wink

thanks for your support
first of all i know that you are a good asm programmer and appreciate this
i cant work on it for some time becouse i am having final exams and lack of time
but the bigger problem is the project is so much big as i have learned more about the icq protocol
my first attempt is just xoring the password and then with this xored password and some uin i am going to create the connection to the icq server
please look at the password xoring docs i have posted here
i know you can help if u take some time on this

Hi VeSCeRa,

I thank you for your praises. Currently I am adding roasting password into your faim.asm that you have uploaded.

I can't wait for the first login packet. That's would be the milestone. Hehe. If you do need help, do paste more information on the things needed for login. Perhaps I will add moer code into faim.asm (The code that you have uploaded on the board in the earlier posts)

yes i am excited too but i really have no more time for the moment becouse of my final exams

your roaster was working perfect but in the manual the letters are lowercase but in our roaster the roasted pasword contains the letters in uppercase

can u make comments to the roasting code ? it will be very educative for me Smile

in the oscar doc it says
Roasting is performed by first xoring each byte in the password with the equivalent modulo byte in the roasting array ( 0xF3, 0x26, 0x81, 0xC4, 0x39, 0x86, 0xDB, 0x92, 0x71, 0xA3, 0xB9, 0xE6, 0x53, 0x7A, 0x95, 0x7C )

so i have changed them to their char values it makes
roasting array = Ã³&?Ã„9â€ Ã›â€™qÂ£Â¹Ã¦Szâ€¢|
and tested the passwords it really works

but the problem is, in the first packet we should have

i can make the roasted password but it the result is a string but we need the hex code or the corresponding ascii values may be we should add another label to the roaster that shows the ascii values that we will add to the packet

Finally I taken a detailed look at the documentation. Wow. I am amazed by how well documentated the documentation is. Personally I think it is better to make use of md5 to send the password, but nevertheless that could be added later. For now, we could work on the roasting password.

Give me a some time, and I suppose I will be able to produce the first login packet and I will post it here. Yes, I will try to remember to add comments for the roasting password part. I displayed the hex in uppercase because I feel that hexvalues look better in uppercase as opposed to lowercase. Just a personally perferrance. If you do not like it just change the code on line 90 and 95 to add xx, 39

btw, do you know I have added you?

Here's what I have added. Take a look. Yes the login packet is created and sent, though I have not worked on the receiving part. Will work on it when I have more time. For now just please tell me if I am correct with the implementations. Have a nice day then..

[edit]Attachment removed, look at the later post

I have added more code. There will be an int3 in my code so that it will break into my JIT which would be ollydbg. Dump the value in ebx and you will see the response from the server Cool

I will add more code on the response by the server on a later date...

It is not a crash. It is a breakpoint. Refer to the previous post on it. In fact, I am more interested in the response given by the server.
