In the modern world, we need encryption that can be applied rapidly and efficiently. It's also a pain in the neck to implement.

It's Surprisingly Easy to Be More Secure Online For the next message, you use the next key. Picture tearing the top sheet from a pad of keys and burning it. And then-this is important-you both destroy the key. Your associate applies the key again to decrypt the message.

You and your associate both have access to a random, unique key that's at least the length of the message to be encrypted. More recent, but also historical, is the one-time pad, an encryption system that's totally uncrackable.
