There is no encryption that is perfectly safe.
As for various sites requesting for using numbers in passwords it is only to prevent pasword breaking by using dictionarry attack wich is a lot faster as brute force attack becouse it is guesing password with the help of prechoosen words. Ass for using capital letters it only prolongs brute force attack, that's all.
