1st part
2nd part
well u said my crackme was lame, then i built another 1.
tell me how it is.

it work in the same way like the previous one just harder. made out of lena's keygen samples. ignore the about button, i forgot to remove it, and the copy button check password.
the title is because i tried to use spaghetti code on it, but found a better way.
also ollydbg 2.0 can help ALOT on this one. the only problem ollydbg 2 cant open it... i get an access violation............

Which steps of the tutorials did you use to make the keygen? I want to know to see if I have a chance at cracking it xD.

Code: 1337EST
A little better than the other ones.

Edit: Probably should explain how I got this. Set a break point on GetDlgItemTextA. Trace into the call (4011e9). Go all the way to 403031 and go into that call. Keep tracing till you get to 41d016. This is where it is done. You can see the key it is going to compare to )++?=KL. Then you will notice it subtracts 8 from each character that the user inputs (41d03f). This is how it is done. Hope this helps someone.

ok now let me tell u how this all work.

a. u dont have a chance against it if ur not using anti outdbgstring and isdbgpresent plugins. thats because i used both of them, if u get detected on isdbg the program will jump to the password checking routine without making the password so the password is zero.

b.if u try to nop outputdebugstring or its call ull get detected and go to outter space because theres a crc check.

c.i didnt steal lena's code, i only used her code in the beginning, all the loadbitmap, getmodulehandle and program entry stuff. the rest of the code i programmed myself

d.i only used some api's useless for the program to put them in the header. then i went to ollydbg, and programmed all the password making, checking, crcing, anti debugging, and stuff. but the code was too short. it was only 1000 bytes. so i added some hunderds of thousands of nops, and made my code jump to another part of the code and continue from there

e.i filled all the nops with useless commands.

f.im soon posting the crackme my friend gave me, i alredy cracked it. the only good protection it has is the fact its .NET programmed. its the best example to crackmes where .NET only helps.
