Challenge of Reverse Engineering

Hello, everyone!I want to present my first keygenme in quite a while. This one is a continuation of a series I started 4 years ago. (You can find Fun KeygenMe #0 on crackmes.de, of course.)The main goal with this "series" is to help ease novices into the art of reversing (patching, keygenning, etc.) while having a bit of fun. I hope that you guys will solve this and provide tutorials. Hopefully the tutorials will be spread around the Internet for all new people to enjoy and learn from!Features of this keygenme: Coded (poorly) in MASM Not packed No cryptos Simple yet tricky? Difficulty: 1-2/10 I have it on good authority that this keygenme is a 1 or 2 on the crackmes.de…

lARP v2.0 Ultimate My 2008 challenge is this small UnpackMe from Ultimate version of lARP protector. All options checked except pre-compression. Just unpack. Big thanks to my buddies Ufo-Pu55y for researching some really neat stuff and jstorme for his continued support and testing. Thanks guys, I shall remember you in my morning, noon and evening lARP prayers Remark1: when it's all too obvious that you are on a reverser's system, a lARP'ed file may display a warning or even crash, also outside debugger In such case, just unpack to remove all limitations Remark2: there is now some experimental code in lARP. Love and best care have been applied to make it, still, if …

Hey tuts4you, I used some public well known obfuscators to protect a simple crackme. Let me know if you can unpack/deobfuscate + crack it! Picture: DL link: https://mega.co.nz/#!p4pVCYIC!w1DjcZoUHP8_1ogT8W1yCyLI-5u_RhnZdldFvtH6vHw Virustotal link: https://www.virustotal.com/nl/file/093eb0aad057a05ffef5a5673a636478fed5f6ea790b9686f76e4f1261bf5baf/analysis/ I know most of you can do it, just wanting to know if it stops the 'average' person! Goodluck!

Hello. This crackme is a bit of a challenge and may be the first crackme I have actually put some effort to. Half of this crackme is based on a library that I have coded and for wich I will provide the source code if the crackme is solved. Thanks. If the crackme crashes on some given keys - dont bitch this could be fixed but honestly I don't see a reason to. Writte a keygen and state a few words about the challenge. Greetings, xSRTsect.
