List all installed packages: adb shell pm list packages
Find the package you want to download and copy the full package name. Example: com.example.app

	"""Cifrador simple basado en cifrado de Vernam
	hecho por @iordic

	Este script está creado con fines educativos para tener nociones de cifrado simétrico
	basándonos en el algoritmo más simple que se me ha ocurrido: el cifrado Vernam.

	Se puede usar con cualquier fichero, ya que el fichero de entrada se lee la
	información binaria del fichero. De todos modos te recomiendo que uses ficheros de
	texto para comprobar los resultados.

	#include <stdio.h>

	// Declare constant sizes
	const int rows = 8;
	const int cols = 6;

	// Seed for random numbers generation
