    This is my first KeyGenMe. I think this is pretty easy (I may have over-rated, I think was 1 but maybe a 2 in difficult). Rules 1. No Patching (unless u really want to....) [Not a Winner!] 2. No Bruteforcing 3. Allowed to use PeiD (really useless) 4. Make a working KeyGen [NOT A SELF KEYGEN, PLEASE!] 5. If can't make a keyGen, atleast post the Name and Serial if u have it. Enojoy, and remember this is my FIRST one ever made, in VB If no one figures out for a while I might give a hint. If someone can find a working Name and Serial then if they request a Keygen, PM me and we will talk Hey be a big boy or girl, tell me what I need to work on or approve on! First_KeyGenMe.zip

    Hello, Yesterday I created my first CrackMe and decided to share with all of you. I guess it's a little easy but not to easy. It's not Encrypted or anything, or Encoding; Just Compiled. Post User: Pass: And Auth: Rules~~~~~ 1. No Patching 2. Find a correct working pass 3. Find a correct password ~[Hint]~ If you get a box saying "Use this for Auth, (then a number or Letter) WRITE DOWN! 4. Find a correct Authorization code 5. Well you can't keygen, it's a CrackMe 6. It's kind of easy, but my first one Hints 1. Look for boxes. 2. Look for repeated var. 3. Figure it out. CrackMe V.1 Crackme.zip http://www.speedyshare.com/652732472.htm…

    This is an attempt to code an "uncrackable" program in assembler. See http://www.tuts4you.com/forum/index.php?sh...c=12949&hl= to read the complete story. Aesthetics-only patching is NOT a valid solution! e.g. editing "UNREGISTERED" into whatever in a resources editor. Of course that this doesn't effectively register anything, right? Adding code, etc to make the ReverseMe display something isn't a valid thing either, right? You may however patch the reg scheme so that false data is still accepted as valid. If patching, please explain your solution so that I can verify its validity. It's clear that a keygen is preferred. Good luck and have fun lena151. ReverseMe_9_b…
