Hi All,
This is a CrackMe which requires a password to reveal/show/get the secret text. The password you fill in undergoes an algo, the outcome of the algo determines if the program will give you the right secret text.
If you think you have found the right secret text, fil it in the following site to check if you are right: http://members.lycos.nl/wietsite/fp.php Fill in you secret as fp.php?x=secret_text The php script will say to you if you have the correct text or not....

NO RULES FOR THIS CRACKME, do what you want.

Goodluck and send me your solution to x2barchain2x@hotmail.com.
Grtz Devoney

07. Feb 2007		Devoney, I found out what to type and it works with the crackme, but on the lycos website it says that my secret word is wrong. Vhy??
Zaphod
07. Feb 2007		Ooops - I just discovered that I should type the secret word instead of secret_text, not after.
I don't feel sleepy, but I guess I must be...:)
Everything is okay, I got the thumbs-up from the website.

10. Feb 2007		Nice comment ;)
It costed me a lot of time to calculate all the bytes needed to be written. But I was quiete tired at that moment, that did play a role to I think.... I want to make a CrackMe kinda like this one with a lot of code depending on the user input... But it costs a lot of time, maybe I could make a simple app to do all the calculating for me :P

11. Feb 2007		Hi Devoney, if you want to make another crackme based on same logic, then here are some ideas;
1. Code complete app (with wanted code as well)
2. Extract these bytes using Table Extractor 1.34 by Thigo
3. Fill these bytes with NOP/junk in app.
4. Use some algo e.g. MD5 etc.(an algo that's reversible)
to get required user-input.
5. If you want code-to-be-devrived to be big, you can use MD5-per-byte etc(there can be millions of ideas).
6. BUT: if your algo required-bytes are big-in-quantity, then you'll have to provide user MORE AND CLEAR hints as well.

02. Nov 2007		Is this one to simple for you? Try my 3th crackme called "CrackMe 3.0" by Devoney, it is based on the same principle.

thanks for appreciating this one!
