    First of all, this isn't my crackme. This is Sharpe's from Crackmes.de. It took me a little while to solve it, and when I did, I was very pleased with the programming and programmer. It's a very good crackme! I warn you though, the difficulty is a little under-rated. Enjoy! -Cobrasniper555 eight.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…

    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…
