 |
|
Folks im back =]. This is my 3rd Keygen me, and it should be harder, it doesnt have any string references . And thats what most of you guys usually depend on  . So here is my crackme.
Rules:
1. user name must be 7-10 chars and you cant put numbers in your name =[.
2. No patching
3. Find a serial for your name
4. Try to make a keygen

name: zartraz
serial: 25094290AF-AF25095490-FO-1879893253-1386
Note: KeyMe can only be used to check serial on FIRST run. You might not be reseting your variables after using them - because it will incorrectly generate serial numbers after the first time. This is causing it to reject valid serial numbers. Example - enter this name/serial, then check it again - it's considered invalid.

Well... There are strings in there (I didn't look at first, just assumed you where telling the truth) started scrolling up from the bottom, noticed it looks like Delphi code and looked for a delphi type compare.
Delphi normally has "compares" like this;
CALL something
JNZ badboy
goodboy here
badboy: badboy!
And say this;
| Code: |
0045C83C |. E8 5382FAFF CALL KeyMe.00404A94
0045C841 |. 75 10 JNZ SHORT KeyMe.0045C853
0045C843 |. BA 24C94500 MOV EDX,KeyMe.0045C924 ; ASCII "Congrats"
|
Set a breakpoint at 0045C83C and you'll see your serial entered, and the one being checked against it in the registers.
Works fine on my computer. Havn't looked at how it's generated yet though.

Ready whats already been posted. He didn't reset his variables, thats why it continues to make bad serials after first run.

it always changes...
and like zart said, if i understand him right, after it makes the variable of "Wrong" so it doesnt reset itself and keep making new serials and even the correct 1 when its correct so it doesnt show correct it shows wrong? uhh i tried finding it but i can get to my bp without clicking Submit button... >.<
my last 1 was.. Symboll 25094290AF-AF25094290-AF50188443-1386 but always changes O_o
