Si iata noul meu crackme...trebuie sa aflati keywordul

http://dl.getdropbox.com/u/329033/Crackme7.exe

E facut in Visual C# express 2008 pentru cei interesati.

Parola: lalalbala

Vine acusi un altul...

Proudly presenting:

Crack me no. 8.

E o surpriza mai ales pentru fanii Star Wars.

Target: Sa-l determini pe Master Yoda sa-ti admire inteligenta...

Cum? Crack, patch, aflarea raspunsurilor, etc.

Spor!

PS. Ideal ar fi fost sa ne fi impiedicat si prin niste coduri sursa pe topicul asta...

PS2. Am adaugat si varianta fara sleep pentru cei mai nerabdatori...

[CyberWolf08]

Ai bagat tu delay-uri ca merge al naibii de incet..?

Da...ai bagat tu sleep-uri...

P.S. "To the Academy I welcome you, young Padawan!"

Scuze de mistype...

Da, e "padawan"...

Am pus si o varianta fara delay.

[xact]

Scuze ca n-am mai dat pe aici, am fost plecat pe coclauri...

Hint: am folosit o functie de decriptare a stringurilor. Nu e nevoie decat sa urmariti functia respectiva (proceseaza tot ce inseamna stringuri encriptate) si o sa gasiti passphrase-urile.

CrackMe output:

Master Yoda: To the Academy I welcome you, young Padwan !

Hmmmm.....

Doubt in your ways your spirit reveals. Your name, do you know ?

Padwan: skywalker. luke skywalker.

Master Yoda: Your name The Force has heard. It's worthy of a bright future!

....still...

Do know your place in The Universe ?

Padwan: i must follow the path of the force.

Master Yoda: Congratulations! You are wise and your spirit strong !

Functia de decodare e facuta in C#

using System;

namespace HttpClient.RST
{
    public class CrackMe08 : IMissoin
    {
        public void Execute()
        {
            Console.WriteLine(Decode("-sdlkbvzjt fjvk!-sdlkbvzjt"));
            Console.WriteLine(Decode("-fbsng fgu gn!gu`q fgu xnmkpe!sttn j"));
        }

        /// <summary>
        /// Decodes the string.
        /// </summary>
        /// <param name="source">Encoded string.</param>
        /// <returns>Decoded string.</returns>
        private static string Decode(string source)
        {
            string result = string.Empty;
            for (int i = source.Length - 1; i > -1; i--)
                result += source[i] != ' ' ? ((char) (source[i] + ((source.Length - i)%2 == 0 ? 1 : -1))) : ' ';
            return result;
        }
    }
}

Din pacate nu cred ca o sa am timp sa fac un CrackMe prea curand, deci... daca pune altcineva nu ma supar.
