All the computers in the world wouldn't be able to brute force AES with a strong key in less than 10 quadrillion years [1]. They would be better off spending millions in four-leaf clovers and faceroll the password.
That said if they knew a way to crack AES or RSA it would be a different story (a nightmare).
