If serial is -ve then it says invalid even if that is what your proggie has generated.
Is this a bug or some kind of a trick?
08. Jul 2008
serial -ve its not possible, something went wrong on your side... :) tell me for what name its generating that serial please.
08. Jul 2008
i will make a keygen soon
08. Jul 2008
very well done crackme, i just submitted my solution + keygen.

Thanks Haykuro!! :) im already improving on it and preparing my 2nd KeygenMe
09. Jul 2008
Ahh, my bad. I hadn't patched the anti-debug properly :)
Nice cme btw :)

Haykuro, your solution to my crackme is wrong, it doesnt generate all valid serials... some names will give invalid serials on your keygen. :) try this one for example:

user: Eras3r
10. Jul 2008
and i just checked the ReWrit solution and its wrong too... :)
just test some names in the keygens provided by these 2 members in my original exe and they will fail sometimes.
as before, i give the username: Eras3r as example. test it
on my orig. exe with the serial generated by the solutions. it will fail
10. Jul 2008
i've made the fix and resubmitted :)

an interesting keygenme, i just submitted keygen
10. Jul 2008
Solved. Pretty alright. Like the use of signed numbers and little trick at the end to get around it.

Good crackme for beginners like myself. Wrote a keygen in asm but not going to submit it because here are better already with coments.

Good work!

Author should have warned that these crackme#1 are packed with anti-debug and strings are encrypted too. Thus I think these are not so suitable for noobs. Also crackme#2 and crackme#3 are infected -Trojan Horse and Suspicious.Bredolab- as detected by Symantec. Anyway thanks for contribution.
