This is my first Unpack me. No rules, good luck. Tell me what you think. Good luck! I would like to thank Lena for her tutorial program. Toast__s_Unpackme.zip

Hi, this one might be interesting, if you want to get familiar with hashes (like me). So it's intentionally WITHOUT any tricks, packers, mods or **** - coded dead straight. Fishing/Patching/Zonking out - 0 Points Keygenning - 1337 Points Good luck: KeygenMe__hASSh__1_.rar

Very easy fishme: http://downtown.vc/index.php?page=main&id=89092038&name=FishMe.v.1.exe.rar

This unpackme is protected with the latest version of Xheo CodeVeil I hope u enjoy reversing this nice protection Regards, LibX // RETeam UnpackMe.rar

Hehe.....My Old KeyGenMe,It's my first KeyGenme, :cool: keygenmes1.rar :cool:

I got bored and wrote this........should be pretty easy. Rules: 1. No Patching 2. No Self-Keygens (Refer to rule #1) 3. No Fishing - Valid Name & Serial Not Valid Solution 4. Write A Tutorial If You Feel Like It Valid Solution: Write A Working Keygen Code Snipits Are Not KeyGens...Nor Valid Solution Have Fun Dustyh1981 DrPepUr__3_KeyGenME.rar

Hi, here's level 2: KeygenMe__hASSh__2_.rar Fishing/Selfkeygenning/loveing : 0 points Ripping : 1 point Recognizing&Owning : 1337 pointz If you're after 0 or 1 point, it's easy like ****. Again nothing protected or hidden. Just a naked row of instructions. But if you're after the full win, this one might be a small bitch.. dunno. Have phun :happy:

hello... non-ripped valid keygen with source is the golden solution.. http://www.mediafire.com/?vrfj9x1zsyc

This is my first attempt at a KeyGenMe app . I wrote an mp3 player app. purely for programming practice so do not expect state of the art graphics or playback. The app as presented is an 'unregistered' version which a correct serial will convert to the 'registered' state. Please note that the app. will not run directly but must be executed via a shortcut. When you solve it please write a tutorial as some parts of the solution may answer at least one question I have seen posted on the forum. I wrote the whole thing in assembly language in Windows XP SP2, and it will not work on non NT based systems. Happy reversing in whatever you are working on Cheers InsaneFIDO FID…

Well, i decided to make this after being board... Points - Fished Key = 0 - Self-KeyGen = 0 - KeyGen = 1000 CrackMe v3.0 - Simple Key Generation - Simple Anti-Breakpoint (On One Function) Im looking for a KeyGen, I will just ignore Patches and Fished Keys... CrackMeV3.zip

This is a difficult crackme. Yeh... you can patch it but thats not what i want. I want the Key! CrackMe v2.0 - MD5 Encryption MD5 Key Information Key Length : 16 Key Characters : Numbers MD5 Encryption Module : MD5(MD5(Key).Salt) I will be suprised when you find the key, thats if you do... Good Luck! CrackMeV2.zip

eXPressor 1.6.0.1 I haven't patched the silly nag - if it pops up on you - but you get the idea... http://www.tuts4you.com/download.php?view.2179 Ted.

Hi everyone It's been a while since we wrote a .NET crackme so this is a nice one to refresh your minds It's not very hard but needs a little brain, Of course you can do it in one patch but It's not allowed so you must write a valid keygen and a tutor for the rest of us to show us how you solved it. Enjoy... K_CrackME_15.rar

Anything goes. Read the readme and good luck. IMO much harder than the last ver bleh Compatibility issues fixed. Download new ver here: http://www.filesend.net/download.php?f=b2d...238f8690e0d8619 Sorry for any problems.

Simple keygen mes 1 & 2 I wrote recently. They are written in VB 6.0. Write me a tut and make me a keygen NOTE: I said it was EASY so if you are looking for a hard challenge, dont bother downloading. Key4LilBro__1.zip Key4lilbro__2.zip

This is a simple KeygenMe that I put together in ASM. It should'nt be too hard. It says that you should solutions upload to crackmes.de, because I created it for that site in the first place, but you can just upload your solutions here. Good KGM1_qwertydid.zip

Hi Every Body This Is Persian Lock Which Write in VB Test IT For Any Method Of Cracking & Make Tutorial Very Easy To try Thanks To all For Taking Time To Look At This Crack me PersianLock.rar

In what little time I have been messing around in RCE I have never came across a Vb target in P-Code. I never gave P-code much thought until on PSC I seen somebody had posted their code and labeled it "Uncrackable". So... I had to give it a try, I downloaded it and went to work but everything I had learned seemed not to apply. It didn't take long to see it was P-Code and for about 2 seconds I almost gave up. After an hour or so I thought I could write a little reg-routine and compile it in p-code so when I had it loaded in Olly and Vb-Decomp I would know what I was looking for. My effort was rewarded I learned enough to tear the "Uncrackable" a new one. So if you have nev…

I wrote this just trying to learn a little about ASM so if my code is sloppy keep in mind I have been programming in ASM a total of a couple weeks at most.. So it shouldn't be too hard. Happy Cracking.... Dustyh1981 DrPepUr__2.rar

Hello guys , I made this KeygenMe about 3 months ago in AT4RE ... and i would like to share it here just for fun :happy: . ------------------- The KeygenMe is not Packed/Encrypted . The Algorithm is really for kids , but beware of tricks . I need a working Keygen NOT a serial for ur name . Good luck, GM Sadistic_X__2.rar

hi all this challenge for newbie's KeyFileME_3.rar

Just wanting to test out this auth system before we implement it. http://rapidshare.de/files/38212602/crackme.rar.html By cracking it, I'm referring to the trial portion, not the "congratz" message, but you can do that too if you want to feel special.
