Pad ciphers is to not use computers at all for encryption/decryption. You do want something truly random to make the pad and that is usually a computer of some sort. The idea is to have a computer make the One-time pad data while Alice and
a computer to encrypt or decrypt, you leave behind data without even knowing it and it’s usually a variable that you cannot properly control. But again, we’re just having fun.</p>
Bob are together and in a safe place. That computer should not belong to either Alice or Bob and would likely be owned by Alice and Bob’s handlers. It shouldn’t be connected to any network, and for real security, should be annihilated with
antimatter after use. True randomness is hard to come by but that’s another post. When using a computer to encrypt or decrypt, Alice or Bob could leave behind data without even knowing it and it’s usually a variable that they cannot properly
control. Again, we’re just having fun.</p>

and therefore would have to assume that on the conversion table, there are numbers that go up to 93 and so on. Often time codebooks use numbers like this as well.</p>

<p>What if Alice and Bob were never in the same room together? As soon as anyone, outside Alice and Bob, put their hands on a One-time pad, it should be considered compromised and, for all intents and purposes, useless.</p>
