Re: Simple Autoit CrackMe

 

Hola a todos :D

 

Pues me di un tiempo para ver este crackme y concluyo en que no entiendo ni papas jajaja

después de ver correr el code procure recrear nuevamente el algoritmo que desencripta las cadenas pensando que este podía ser el password

 

0x4E5D315F0F94A4D52 A4E9B27AC248A9A8E870AF803293218

 

el resultado es este:

 

OMG Just Simple CrackMe

y la siguiente cadena no se que onda pero no me la desencripta correctamente

 

en fin hasta donde vi creo que esto "OMG Just Simple CrackMe" debería dar el resultado de exito no? o me equivoco

igual gracias por el crackme

 

un saludo y suerte.
