Ugh I hate using the command "if". Since anyone with basic ollydbg knowledge can just set a breakpoint on my compares or "if"s. I tried...

Code:

xor eax,edx ; eax = password while edx = user input
cmp eax,0
je right


But someone can easily set a breakpoint on the xor routine...


Any help?

dont put the real password in the file.
Try to calculate the password from the input:
Code:
Input = 2
password1 = Input * Input
password1 = Power(Input ,Input)
//and now compare
if password1 ==password1
//the code here


**the code is not in any language, just to see the idea.

Looks like Visual Basic lol. Also looks like a keygen but more simple.


Also your using the if statement. Also viewable by breakpointing :S
