hi,from http://www.unpack.cn/viewthread.php?tid=31...;extra=page%3D1 SentinelHardwareKey加壳Notepad试炼品 鉴于坛主fly的建议和大家的兴趣，用shk狗加了一个记事本（英文版xp）的壳。大家试试看能否无狗脱壳。 加密具体参数： 1 3层壳（没有用最强的5层壳）。 2 20对Query，少一些query，不要搞得太变态。数据长度4 bytes 3 试用日期限制，到2009年1月31日。 下载地址： http://rapidshare.de/files/41287409/NOTEPAD.rar.html http://www.dinknet.com/web/productlist.asp...;sortPath=0,192, NOTEPAD.rar

Hi , first of all im new here but i have posted this keygenme on other community sites and for my surprise only 3 find the solution and made a keygen so i want to see whats up here you are given a verify code and after that code you have to generate the autentification code If you enter a wrong code when you press OK it will exit If you enter the correct code when you press OK it will give you a window with : "You did it " message! Good luck! keygenme.rar

Welcome to a new challange by mucki! mucki_protector_II.rar Ted.

While trying to figure out another very easy crackme I was messing with VB. I ended up making my own CrackMe (very first!!!! ) This is very easy, initially it was too easy, first BP and serial was sitting in your face lol, so I added an extra compare (hint) Rules; NO PATCHING! This is too easy to Patch Serial Fishing is Acceptable on 1 Condition - When Posting your serial, you must also Post the Process you used to get the serial Keygenning is Ultimate Goal!

Here is a challenge for all. Some time ago, I coded an (freeware for medical purposes) application which was never cracked. Too stupid, not worth bothering or too difficult ?!? Dunno ... but I hope you'll tell me. BTW, a registration scheme was only implemented to keep track of people's use (free registration). To comply with forum rules, I have grabbed the registration scheme and made a ReverseMe from it. Everything is allowed : serialfishing, patching, brute forcing ... the ultimate goal is a keygen. The only nag in the real stuff is when clicking the "Register" button. This reverseMe has more to make it easier. Each time an action is required, the registration sc…

Your Mission if you choose Unpack this file and tell me the original OEP and original File Size. some things to consider: anti olly if you can bypass this please tell me how;) , anti dumping and a few other things let me know! PS. most of the file size is the chiptune converted to c++ table array (adds to the encryption bigger the file = more encryption ps: attach to process example Sorry a little drunk right now maybe this is simple for you to bypass but let me know PS. I am Nefarious PS. The File size is higher now then it is Uncryptedme NefariousUnCryptMe.zip

I hope you can keygen it XUECRACK.rar
