- Gasiti algoritmu` de calculare a 'serialului'

- Faceti un keygen pe baza algoritmului .

Nu va fi greu pentru ca am zis sa fac o serie de crackme-uri incepand cu un nivel scazut de dificultate .

`Algoritmii` sunt formatii din cel mult 4 linii de cod (deci permutari , operatii matematice adunare scadere ..etc:)

Nu va ganditi la ceva complicat ,criptare etc ...

Keygenu aici , si pe PM o mica descriere .

*Atentie nu vreau un self-keygen .

The application failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem.

Tipic windows 8-| . si nu are nici icoana file-u. zici ca e .com

Vad ca nimeni nu a avut cheful sa incerce macar .

Au fost probleme cu prima varianta compilata in Visual C++ , am recompilat in DevC++ si am modificat linkurile atunci.

Solutia era urmatorea :

ex User : ABCD

Serial : A-68-67-66-65

Se forma serialul din lit A urmata de codurile ascii ale literelor luate de la sfarsit la inceput . D C B A .


char serial[100] = "A";
int lung = strlen(buf);
for (i=lung-1;i>=0;i--)
{

sprintf(serial,"%s-%d",serial,static_cast<int>(buf[i]));

}

in buf se tinea userul .

In olly arata cam asa .
