Using Models Around Classification

i read that rather than generating a key and then tributing it, you can generate the same identical key in multiple ocasions. So this means that you don't need to distribute your keys at all, meaning they're never at risk alls. D, i read developers can easily down load and include the quippd s t k in the application to increase security their applications and interstructure. Me how they can do this? Yes. We extract from that large amount of random that they've down loaded a single key that's known to both of them at the end points. But it's not vulnerable to that s nown decrypt later piece of that key exchange, because
