It is only partly true the one-pad encryption is unbreakable. The real impact is there is no second message to decrypt if the first one is broken. The big problem is the transmission of the number to the recipient. Now we are back into the world of couriers, stealing the pad(s), moles, spies, etc. So the system is not really feasible in today's high speed world of information. For single transactions with time to get the number securely to the recipient, yes. To handle the millions of banking or security transactions a day, no.

A.K.A. "rubber hose cryptography".

cracking the transmission of the pad would be all but impossible. To crack something you have to KNOW when you randomly hit the right encryption. If all that you are decrypting is random numbers then that is all you would ever see. There would be no way to know which one was the right set of random numbers because ever solution to the attempts at decryption would give back random numbers. That is the real challenge of decrypting computer data. Unless you already know what you are looking for and how to interpret it all you ever have is random bits, even if you stumble on the right decryption. There is much more to it than just computing horsepower.
