One Time Pad (OTP) is an ‘old school’ tool and a method of encrypting messages. As long as the actual One Time Pad is kept secure, the message will be unbreakable. The challenge of using this method is generating truly random sets of numbers. It can be very time consuming and redundant. The ADL-1 One Time Pad machine makes it as easy as the touch of a button, and it is FIELD PORTABLE!
