Hi! I developed an unbreakable encryption method that will replace theVery unlikely.

The Basic IdeaThat is not, and cannot be, a One Time Pad. You start with a finite

Take a small number of One Time Pads. These are of course shared

between two computers. Add an array of random numbers that can be used

as indexes in those One Time Pads. Now, every time you use a code from

one of the pads, use the next value in the array to determine another

code in that same pad with which to swap values. That's basically it.

Now you have a small set of perpetual One Time Pads.

amount of key material, the "small number of pads" and the "array of

random numbers". As soon as a message (or group of messages) has

exceeded the length of all your key material you *must* be reusing at

least a part of it. That changes your scheme from a One Time Pad to a

Two Time Pad, and a TTP is known to be insecure.

To be an OTP the amount of key material must equal or exceed the size

of the message/s. Under no circumstances can any key material be

reused - that is why it is called a ONE TIME Pad.
