“we should look into some non-hackable security”
There’s no such thing. If humans design it, other humans can find a way in.
Russia, Israel, North Korea and a dozen other nations spend billions of dollars and their best brains to access foreign communications. If some guy in his undershorts living in his mother’s basement can access this stuff, tell me why the foreign intel services do not have every one of Hillary’s emails. If this is so we can probably trace several deaths to her carelessness.
The Russians do it all the time. Yt’s called one time cyphers.
